    I enjoy listening to music during all my daily activities. So, I looked forward in receiving these complimentary UA JBL Sport Wireless Flex In-Ear Headphones in exchange for an honest and comprehensive review. While removing this unit out of the box the very first thing I noticed was how light this neckband is, weighing in at only 1.4 oz. The next striking feature is the Flex Zones, which are located on either side of the neckband. I can bend the Flex Zones in or outward for more comfortable fit adjustment around my neck. I can wear the neckband loosely or more firmly to match my activity. Here is what is included in the box: * UA JBL Sport Wireless Flex In-Ear Headphones Neckband Unit. * Micro USB Cable for Charging. * Quick Start Guide * Safety Sheet & Warnings. * Warranty Card * Three Extra Pairs of Silicone Ear tips – Sizes Small, Three (Medium) and Large. * One Winged and One Wingless Ear Tip Enhancer * FREE MapMyRun 12-Month Premium Membership ($30.00 Savings) - Available for download at the App Store and Google Play. SOUND QUALITY: * Bass – Nice deep and robust low frequencies. Playing various music genres the Bass seems to rumble around enough so that I definitely know it's there, but it's not overwhelming. I personally like this level of Bass, but if you want deeper, more potent Bass, these may not be for you. * Mid Range – I like the delivery of the mids. They come through distinctly and is what I expected for this JBL headphone set, which is designed for physical activity and exercise. * Highs – The Highs are more then adequate, and are clearly heard when heavy bass is not featured. The brass and strings are vibrant and clear voice has a nice crispness projection. * Channel Separation – Even at low volume sound settings I found that the stereo channel separation is quite good. **TIP** Use the largest size earbud that will fit comfortably in your ear. It not only enhances stereo channel separation, but it reduces other ambient noises in your area for better sound delivery and enjoyment, similar to passive, noise canceling. The following are the most prominent features of the JBL Sports Flex Build and Design. RUBBERIZED NECKBAND & EAR BUDS: * The UA Sport Wireless Flex has 4 buttons present on either side of the band. On the right side, are Volume/Track buttons. On the left side are the Play/Pause,Power/Pair and a Multi-function button (Run Safe LED, Mic Mute during calls and Siri/Google Now) * Run/Safe Mode – I have learned to really like this feature. It has a singular Blue LED light on the Right side of the unit along with a 5 and ½ inch LED White strip light at the very back of the neckband to help keep me safe in low light conditions.. By pressing the microphone button on the Left side the Run/Safe Mode is activated. There are three safety LED light modes. When I press once the first mode blinks the Blue LED light and neckband strip continually. Press twice and the second mode features 2 blinks 'ON' followed by 2 seconds 'OFF', repeatedly. Pressing the microphone again is the third mode which is 3 blinks 'ON' followed by 3 seconds 'OFF', repeatedly. * Magnetic Ear Buds, which snap together for easy storage. * The attached earphones have an IPX5 rating, which makes them 'sweat-proof', but not waterproof. They cannot be submerged under water. * Automatic Shutdown – After 15 minutes of inactivity the unit goes into power-saving mode. * Flex Zones – I can choose to fit my neckband loose for more comfort, or tighter for more security by adjusting the Flex bands accordingly to my particular activity. * Battery Charge With Speed Charge – It takes me approximately two hours to fully charge my unit for approximately eleven hours of continued use without the LED Run/Safe Mode. However, with Speed Charge, I get one hour of play time after only five minutes of charging. * Bluetooth Versions & Comparability - 4.1, HFP v1.6, HSP v1.2, A2DP v1.2, AVRCP v1.5 * Siri or Google Now Assist – I press my mic button for approximately 5 seconds to activate Siri to make calls, play music, etc. The same will work for Google Now. * Volume Controls (+ or -) Please remember that your Smart Phone or other mobile device sets the Master Volume Control limit for this JBL Sports Flex. * Micro USB Charging Port – Located at the back of the neckband on the bottom side. So, for the past week I have used and evaluated these headphones for the following activities: Jogging, Walking Briskly, Working Out at my Fitness Center, Working in my Garden, and Working in my Yard and Routine Household Chores. With the exception of Jogging, the neckband performed nicely. It was very uncomfortable for me wearing a T-shirt while Jogging because the neckband bounced around my neck constantly. I could not adjust the Flex Zone to make it both secure and comfortable enough to Jog. However, I tried wearing a Polo shirt with a collar while Jogging, and that made a huge difference. I was pleased with the neckband's performance for all my other activities including Working Out at the Fitness Center. The four button controls were easy to learn and operate. I was most impressed that my earbuds stayed firmly in my ear using the winged ear tips no matter what I did. DISLIKES: * There is no carrying pouch for transport or storage. * There is no way to check the battery charge level. The LED indicator on the Right side of the neckband only flashes Red when the battery is low, and, in need of a charge. NOTE – The LED remains a constant Red while charging. * There are no programmed, function announcements. * I worry that the thin wires connecting the ear buds to the neckband are pretty fragile, and may not hold up to much wear and punishment over time. I recommend these UA JBL Sport Wireless Flex In-Ear Headphones for their many features and great sound. These headphones would make a great present to any physically active family member or friends you may have on your Gift List. Because of the Jogging issues I encountered I can honestly only rate these JBL Sports Flex Headphones Four Stars.

    Bass Forward, Gym Friendly Design

    The Under Armour Sport Wireless Flex Bluetooth Earphones are designed to stay put during the most active workout. POSITIVE IMPRESSIONS: 1- Featuring a "Bass Forward" design that I prefer during a workout, they provide a gentle bass "thump" without wrecking the balance between high, mid & low frequencies. Bass is featured, but does not dominate the audio; this is a good thing. 2- The grey color / black wires blend & are unobtrusive. This color will not stand out in a crowd, but will not offend, either. 2- Ultra light weight design. 3- Flex feature theoretically provides an adjustable fit. In practice, I did not find the adjustability sufficient to change the already comfortable fit; perhaps you may. 4- 12 Hour rated battery life actually proved to be accurate. This is excellent! 5- Bright LED strip adds visibility at night. 6- Water resistant design with IPX5 rating (not submersible but water resistant). 7- Good wireless phone call capability; the microphone works well. 8- Micro USB charging cable is included; this is a standard connection, a smart move; you probably already have such a cable in your arsenal, so if you lose it, it is very economical & easy to find & replace. 9- I like the "enhancers" (silicone fins), but enhancers without fins are included, as well. CONCERNS: 1- The ear pieces arrive compressed so tightly in their custom foam packaging, a forceful tug on the ultra thin wire is necessary to eject them from the suffocating factory sheathe. This cannot be good for the slim wires for each earpiece. The overzealous packaging could easily cause a broken wire failure before you wear them the first time. 2- Buttons are the smallest of any headphones or earphones I have seen to date. I have size XXL hands, so I have to press the tiny controls with my fingernails. To make matters worse, they require a forceful push on their hard surfaces. 3- Spend time to try each size ear tip (Small / Medium / Large) while carefully listening to your favorite song that you know the best!! Focus on the bass. Press the earphones in toward your head. If the bass increases, try a size smaller ear tip. I tried a larger size ear tip & 10 minutes later, my ears hurt & the bass was even less. Fit is more critical to sound than any earphones I have ever worn. They are labor intensive to set up. They ship with Medium ear tips (which makes sense). I spent 30 minutes trying all ear tips listening to the same song, but when you get the right ear tips for your ears, they sound consistent; bass does not change as you press them in toward your head. No movement affects the sound. I was very disappointed with bass response when I put them in my ears for the first time. Spend (a lot of) time & you will be rewarded by balanced audio. -1 Point. 4- No Carrying Case - this is disappointing because for $129, I expect these earphones to last awhile. I am willing to go the extra effort to protect them & not throw them in a backpack or gym bag, where the emaciated wires would not stand a chance of not breaking. So how am I supposed to carry them to & from workouts? Who sells a carry pouch designed to safely protect these? After spending $129, why should I have to search for a unique carry case? 5- The wires are non retractible, unlike some Bluetooth earphones that I own. They form an unattractive large loop, connecting to the main unit that is around your neck. 6- Limited Bluetooth range. Sound dropped out 25 feet away at most & much closer if any walls or barriers are between the earphones & the phone or tablet source. What bothers me the most is when sound cuts out for a second with no barriers & the iPhone 6S Plus is sitting on my desk, 2 feet away. This happens on average, once during every other song. I consider this the biggest concern I have with these headphones. -1 Point. CONCLUSION: These Bluetooth Earphones require more set-up time and effort than any other I have owned. They offer very good sound if you are willing to put in the time. The Bluetooth signal dropping out as mentioned in Concern #6 is my biggest concern; they earn a 3-Star Rating.

    Under Armour and JBL are the perfect pair. These headphones are amazing and I highly recommend! If you exercise then you will definitely want to pick up a pair of these headphones because they are made especially for you! First things first for me is always comfort! I am very pleased with the comfort of the ear buds and the rest of the headphones. I normally go for completely wireless headphones but the support of these are just as great. It is light weight and if you find yourself exercising you can adjust the flex zones to fit better around your neck so that the headphones won't come off. I was able to do sit ups and they did not move. They hug my neck comfortably. Sound is another thing that is very important to me and I love it. I turned off the equalizer off of my apple music app because the sound is great without it! Also, I normally have to listen my music all the way with all other headphones and I actually have the volume slightly close to all the way. There is true noise cancellation with the volume at a reasonable level and the best part, everyone in the room can not hear what you are listening to. Also please be aware, if the ear buds are hurting your ears take them out and re-put them in your ear a different way. I have really small ears and they fit perfectly. Battery life is very impressive for me. I listened for three hours the first time and the battery symbol on my phone only went down a little bit. I am currently listening one hour in and the battery symbol is barely at the halfway mark. So at this point I would think that you can get about 8-10 hours out of these headphones out of the box. The best part that I read in the manual is that you can charge these headphones for about 5 minutes and get an hour of play. If you charge for 2 hours you should get 12 hours of play. Connectivity is very easy, turn the headphones on and turn on bluetooth on your music device and connect UA/JBL Flex. The second time I turned on the headphones it did not automatically sync but the manual says that it will remember the device it initially connect to. I am a little upset that I will have to keep my device pretty close near me when wearing the headphones. I managed to get about 10 feet and the sound started to get distorted and then it stopped playing. Its not a deal breaker but it would be nice to let my phone charge and get things done around the house or leave my phone in the car while outdoors working out or even in the gym. Extras include the lights in the back of the headphones. For all of the night or early morning runners out there there is an LED light that flashes when you turn them on. There are three settings of blinks and be careful when you hold down the mic button to activate. If you press too hard it will activate Siri/Google Now. Just lightly press and listen for the dings. One ding is slow blink, two dings slightly different blinks, three dings slightly different than the other two. Another extra is the app included with the headphones which is amazing! Get the premium account and you can do so many things with the app to include exercise tracking and it even gives you already mapped out trails to try for walking/running. Also connect with other members in the app and start a challenge. I can definitely see myself using this app during workouts and/or walks. Would I buy again and recommend to friends and family? ABSOLUTELY!

    Workout Headphones that Stay Put

    ---SETUP--- The setup for the JBL headphones was quick and simple. Upon turning it on, my iPhone recognized them as “UA JBL Flex” and I was up and running in no time. ---FEATURES--- The key feature of these headphones is that they have a safety blinking LED light for outdoor running. Upon pressing the microphone button (all buttons are multi-functional), you activate 1 of 3 light modes. Each mode will cause a thin layer of white light to blink at different intervals to be noticeable by traffic/other runners while running outside in the dark. I let my wife borrow the headphones and told her to run ahead of me. I could easily see the blinking light from approximately 25 yards away. Another key feature is the flexible arms. These arms only move left or right and are meant to secure the headphones to your neck. They do they job, as not once did I feel that I might lose them while exercising. This feature is good for people with smaller neck girth, as the headphones won’t feel loose and move around during fast movement. My own neck is thick, but I was still able to wear them comfortably. ---PERFORMANCE--- The performance of these headphones is great. Comfort-wise, the pre-installed earbuds fit me just right. There are an included set of different sized earbuds for those with smaller ears. Audio-wise, I was able to hear music while exercising at a comfortable volume without distortion. These aren’t noise canceling headphones. Therefore, you will still hear background noise if it is loud enough, like a car honking or someone yelling directly at you, but the noise is muffled enough to still enjoy your audio. ---EXPECTATIONS--- The product meets my expectations. From sound to comfort level, everything feels just right except for one thing. First, the positives. The headphones are so light, I often forgot that I was wearing them throughout the day. The audio is good for the price and the safety LED light makes me feel safer when wearing them. The one thing I disliked was the way the buttons feel when pressing them. The pressing of the buttons requires more pressure than I am used to for these type of headphones. When I got a phone call, I had to press the button multiple times because I wasn’t pressing deep enough. Changing the volume requires you to press the button multiple times (as holding it moves the track forward or backward). Sometimes, my presses wouldn’t be recognized, so I had to press slightly harder. However, this is just a minor grievance in an otherwise excellent headphones set. If this concerns you, I suggest you ask to try pressing the buttons prior to purchasing, and move on from there. ---VALUE--- The price for the JBL Under Armour Sports Headphones in terms of value is affordable and competitive for similar headphones in its class. Additionally, the headset comes with a code for a 1 year subscription to MapMyRun, an Android/iOS app that helps track your exercises, which is a 30 dollar value in and of itself. ---APPROVAL--- I highly recommend this product for workout buffs or those who want a listening experience while performing fast motions. The flex arms will more than secure themselves to you or can help with adjusting the comfort level on your neck. Even when bench pressing, these won’t fall off like other headphones because of the flex arms.

    Headsets to work & play as hard as you do!

    When I first opened the very nice looking packaging JBL definitely went out of their way to give you the appearance of quality from the outside all the way down to the secure interior packaging. Unfortunately as my initial impressions were a little bit of a letdown as I removed the JBL Under Armour branded wireless headphones from the impressive packaging and my first thought was of how cheap or flimsy they felt which made me wonder how long they would actually last when put through the constant abuse of workouts, jogging, or whatever sport or exercise activities anyone might do before and after work which depending on what each individual does for a living, for example a construction worker who may use them at work as well as all of the above possibilities. Until I realized that the neckband was designed specifically for flexibility in order to tighten or loosen in order to stay where you put them and keep them from flying off like any other headset made in the same style of neckband wireless Bluetooth headset could easily fly off depending on the activity of course. So with this realization in mind, it immediately changed my mind and thinking that this was actually a very well designed neckband and will actually hold up to any and all possible torture that many of these headsets will be put through ultimately testing exactly how well designed to last for the intended buyer's. Only time and use will tell. On to the most important parts of all wireless Bluetooth headphones is how good the Bluetooth is when pairing with a device and staying connected. Which both the pairing and the bluetooth holding the connection are outstanding and the pairing seams almost effortless no matter what device you pair it with and I had 3 different devices currently paired which makes switching from one device to another fast and pain free. I saved the best for last and that is how they sound. For all but the audiophile these really sound pretty good and while you won't get the deepest bass or the highest pitches you might expect from other high priced brands renowned for superb sound, you need to remember exactly what they are designed for and who they are designed for which is a good quality sound when working your body and mind to push the limit while having your specific music to help push you beyond your previous limits. So while not perfect they definitely do a great job for their intended purpose and who knows, many of you will disagree with my assessment and think they sound amazing which I honestly hope is how most people hear them. Last but not least is how the headset performs when used as a phone headset or just listening to talk radio, an audio book, and as a phone in call headset. The sound of any of the above sound excellent which most people would expect and the one lone pitfall is the built-in microphone which I've been told sounds great whenever I stop whatever activity I am doing and basically take a time out to talk when working in my shop but if I try using this headset as a hands free when at work driving a tractor pulling a set of doubles. Well this is where it fails miserably as whoever I'm trying to talk to can barely hear much of what I say but on the plus side, I can hear them just fine which is good if you like one-sided conversations. But JBL did not design nor have they ever claimed that the wireless under armour sport headset has the ability to be used for this purpose and the Mic is just kind of a bonus feature to give user's the added benefit and luxury of the calling feature and with everything put together without any deductions for the Mic, I really feel that this headset is an all around very good sounding wireless headset that I feel should be rated slightly better and would rate them at 4.5 stars as I believe they have made a quality waterproof, sweatproof, and hopefully durable set of headphones to last for several year's of abuse.

    I'm a runner, and I've been through my fair share of headphones. The UA Sport Wireless Flex is my favorite by far. What separates them from the pack for me is neck band. I wasn't sure about it at first as I've owned lightweight in the ear, earbuds, etc, but not a neckband style. What the neckband does is lend a base that can house the electronics, sizable battery, and LED light while taking that weight and spreading it across the base of your neck. That said, this isn't a heavy set of headphones by any means, but it helps make the earbuds feel weightless. For me this is a killer feature, as I've always had problems keeping an earbud in my ear during running. After a mile or two my ears swell a bit and it gets harder to keep them in my ears, especially with the weight of a cable and heavier earbuds. These float in my ears with little to no strain. In my last few runs (5-6 miles max, it's my off-season) not only do they stay in place, but they hardly moved. The lightweight cable between the neckband and earbuds is strong, despite some other reviewers concerns, it feels like it will survive in all but open gym bags without any problem. The neckband also brings an LED light, which is to raise awareness on the road. I'm definitely one for early morning runs, so any thing that can increase my visibility is welcome, but frankly - don't rely on this LED band alone. There is only an LED on the rear headband area, so no front LED coverage. I have a light vest which offers a much better visibility. I suppose if you're an off-road runner it could help bikers see you as they approach from behind, but it doesn't offer a whole lot of light. It does offer several settings: constant blinking, 2x1 second blinks followed by a 1 second pause, and 3x1 second blinks followed by a 1 second pause and off. You can change it by pressing the microphone button briefly. Another positive is the buttons. You get volume on one side, which is convenient. The buttons aren't the easiest to press, but are responsive. The other side (left side) has the power/play/pause combo button, and microphone button. You can use the microphone button to not only change the light effect, but also start your voice assistant, which is a handy feature given the running nature of these headphones. Battery life is solid. I've barely charged them since getting them. Needless to say, unless you're an ultra runner you're not going to have to worry about it dying mid-run. Sound wise, they're top notch. Some might complain about the 'lack of bass' - which I think is crazy. They sound amazing (be sure to get a good seal to your ears). EDM especially pops well, as there is definitely a power EQ curve built in. Mids are slightly muddy with some boominess to bass, but not as exaggerated as certain brands. Given the workout focus, they're just about perfect. I found them plenty loud while at rest. During road running I kept them around 50% volume which was comfortable without completely drowning out the world. I do have some problem with closed sealed earbuds and running - since being aware of your surroundings is so important road running. That said, unless you're wearing open air cans, you're going to be closing yourself off sound wise to the world, so I make sure to take one earbud out in busier areas. The general build is solid. The earbuds themselves being housed in metal, feel quite premium. The ability to pair them together magnetically is nice, but somewhat limited feature. The neckband flexes (hence the name) which allows you to adjust the neckband to stay put. Unless you have a tiny neck, you can use this to keep the neckband from moving too much during a workout. I have a fairly thick neck, so I had no problem keep it in place. The plastic on the neckband is a smooth plastic. Any surface that is designed to come in contact with your skin has a rubber texture to it, which kept it comfortable. Again, I barely felt the neckband during my run, and while I haven't run with it during a half or full yet, it seems like it would not be a problem. All in all it's worth a purchase. It offers excellent sound, comfort, battery life, and functionality without any gimmicks or useless features. I highly recommend this headset.

    Get Your Flex On

    Under Armour Sport Flex Wireless In-Ear Behind-the-Neck Headphones, I was a little nervous and felt like I taking a step backwards in the way of wearable tech. The UA Flex headphones have that banana band that goes around the neck. This design isn't by any means, new to anyone who has used stereo Bluetooth headphones in the past few years, so you either love the design or hate it. So here we are with JBL pushing an old concept with the UA brand. Whatever, right? Well here's the twist. That Flex we spoke of in the name. That actually means something. There are these points on the band, that will literally bend to your will to give you a more secured fit. You can tighten or angle the band to adjust to your neck to keep it in place while putting in work( be it, at your job or in the gym. Heck, even if you're just at play, that band is gonna keep your earbuds in place to keep the tunes continually pumping through your ears. Let's talk about that continuous noise for a moment. You know what? Let's talk about it all day, as these very obedient earphones are going to keep you listening until you get where you're going. There is a 12 hour battery....Yep, I said that. 12 hour battery for continuous listening with the UA Flex. If that's not enough time to get the job done, you're may need to go with wired earphones (that is, if your phone even has a headphone jack.) Most earphones give you 8 hours of listening time, max. That's cool , but if you're giving me the option, I'm going all out for the extra 4 hours. But maybe that's just me...and everyone else. More is still more. The box houses the usual ( headphones, micro USB charging cable extra ear gummies for the right comfort. Warranty and care booklets. The sound quality is more than adequate, for my taste and the there's also little strip that glows when I go for those early jogs. I took these on a 3 mile jog when I first too them out of the box. I didn't have to change the ear gummies or charge them. they where ready to go, right out of the box. I like that. I really like that. They never once felt like they would fall out or even came loose, I'm very happy with the UA Flex from JBL. I can't recommend these enough. You've made it this far into the review, so click over and add them to your cart. I promise, you will not be disappointed. Great job JBL. These are some top notch wireless headphones.

    The people at Under Armour really dropped the ball on this one Context: I've used all kinds of LG tones for years. I use them at work, in the car, in the gym and while riding my motorcycle. Needless to say, I ask lot from my headphones These headphones are straight garbage though. My main complaints are as follows: 1. The buttons suck. These head phones only have four buttons, the 2 on the right control the volume and skipping. The ones on the left pause/play and activate some voice command on your phone. When you are wearing these headphones, it is hard to determine what button you are actually about to press because the buttons are so small. The buttons do have some kind of haptic feedback in the form of these tiny bumps. However, they are super hard to press down on so when you want to pause or adjust the volume, it feels like you are pressing down on a pebble with the tip of your finger. Then if you want to skip or rewind, you have to hold down this uncomfortable tic tac feeling button for 3 seconds! Then for me, when I'm on my bike and wearing gloves, this task becomes infinitely harder. The LG's had switches on both sides that you can just flick to skip or adjust the volume. But that is just me being a fan. 2. The form sucks. These things are "band" style headphones, meaning they rest on your neck. The problem here is that they're not very heavy and the band itself is very short. So what ends up happening is they "plank" on your shoulders and the buttons end up in the air, in front of your neck, rather than resting on your clavicle. This is just dumb. And yeah, they have some kind of bendy straw-like feature but it is really useless. It's a pain to adjust and it just reverts back to it's disgusting ways. Also, the earbuds are not retractable. So when you take them off, or hang them off of something, you have these tentacles hanging off of stuff and getting tangled. I know you know these buds don't retract but when you get used to retracting earbuds, this is just sad. 3. The earbuds themselves are shotty at best. Even though they got these fancy wings, they do not secure to your ear any better (yes I tried different sized buds and fins). In fact, I would say the make less of a secure fit since with the LG's I could hardly hear my exhaust on my bike but these let a lot of external sound leak in. Also, they hurt the inside of your ears after wearing them for extended periods of time. 3. Hardware, The bluetooth range on these is nothing compared to my LG's. Seriously. Also, when making calls, people could never hear me and I could BARELY hear them. The only decent thing I could say about these headphones is that the battery life was good and sound quality is decent when your surroundings are not too noisy. I bought a pair of LG HBS-1100 online. As soon as I put them on, I realized, as much disdain I had for these Under Armour headphones, it was not enough.

    I've had these headphones for a little less than a week now and while they are a decent set of headphones, there are better options available. Right out of the box these came about 90% charged so I was able to pair them and begin using them immediately. They come with three different sizes of ear tips to fit practically anyone, as well as a micro-USB cable and operating instructions. They did not come with a carrying case which is surprising for a pair of headphones that cost $130. I have a pair of JLab Epics that cost less than these that came with a case. Pairing was pretty simple and straightforward. I paired them with my iPhone and noticed that they sounded pretty good for wireless headphones. These are advertised as headphones for an active lifestyle, particularly runners. They are very sturdy, comfortable and are noise cancelling as well. They have a light that flashes on the back of the neck band that can be changed to three different types of flashes. This is a great feature for a runner as the more reflective material you have, the safer you are on those night or pre-dawn runs. As someone who has recently gone back to running, I don't care for the noise cancelling and lack of any adjustability to the sounds. The last thing I want when running is to not be able to hear what's going on around me. This is part of the reason, I gave these two stars. Additionally, the buttons are pretty stiff. When trying to change the track or increase the volume, you have to apply a decent amount of pressure to change them. I also don't like that there are controls on both sides of the neckband. The left side controls the pause/play and Siri/Voice assistant as well as the LED lights on the neckband and the right side controls the volume and tracks. Again, using the buttons requires an excessive amount of pressure in my opinion. I also had problems when receiving calls. It might be because I was still getting used to them, but it was difficult to answer calls using the buttons and there is also no caller name identification. I thought that simple feature was pretty standard on wireless headphones, but its not on these. That is a big bummer for me as I don't always want to pull out my phone or look at my Apple Watch when determining if I want to answer a call. I also was not able to pair these with multiple devices. I initially connected them to my iPhone X and tried to pair them with my Google Pixel and iPod and no joy. Again, that may be user error as the directions seem to indicate that this can be done by holding the play button for 2 seconds while its powered off. All in all, these are a decent set of headphones, but for the price and features, I would look elsewhere. The JLab Epic Executive headphones are about $30 less and have better features, but are noise cancelling as well. I guess for running I will stick to my PowerBeats, but for exercising and working in the yard, I will go with the JLabs or Bose SoundSports. I would not recommend these.

    The JBL / Under Armour Sport Flex headphones are very impressive. My expectations weren't all that high, but boy am I surprised. First, they are packaged very nicely--much better than a competitors around the neck headphones that actually cost more. Props to JBL for not skimping on this aspect. Getting started, the JBLs paired quickly with my phone. Once around my neck, they felt weightless and secure. I did about 30 min of running on the treadmill without any issue. The earbuds always felt secure. My other over the neck headphones are a little too flexible/limp. The JBLs provide just the right amount of rigidity and just the right amount of flex. Additionally, the earbuds are magnetized so they can stick together when not in your ear. This is good if you take them out for a bit, they are flopping all over. Another issue I've experienced with my other pair. As far as sound go, I think these provide a really good sound. It's not going to transport you to the concert hall like a $500 pair might, but they are actually very good. Decent bass with good mids and highs. The silicone tips fit my ear perfectly, but there are other sizes included. I think the fit can make a big difference in the sound you experience so make sure the fit is right for you. Either way, I can tell the hardware behind the tips is quality and will power you through your workout or if you're just sitting at your desk. The charge time is rated at 12 hours. Actual use is pretty close to this. I tried it fully charged and started at 8am. I got about 2 full work days out of it and that's about right with meetings and interruptions. The neckband does have a nice LED light on the back with several different settings. I enjoyed it and found it interesting, but it's probably more of a conversation piece or for show than actually practical. I wouldn't rely on it to catch the attention of some texting driver at night, but I guess every little bit helps. In conclusion, I'd highly recommend these headphones for the active person or someone who just wants a nice set of headphones to wear at work. I don't care to have the over the ear kind as it can mess up my hair and they are so good at isolating me from my environment. These will give you some music to jam to whether you're working out or working on a spreadsheet and can be easily pulled out/put back in if someone pops in for a quick meeting.

    Give the design a chance, I'm glad I did....

    At first blush, I was taken back by the design. I was thinking "What, why are these things just hanging here". But then as I explored these for awhile, it became more clear what was going on. They are a neckband wearable, with the actual earphones that will be placed into your ear. Okay, many of those over the ear bands are awkward and hard to get on and off. These do something different. The sit on the part of the ear just above the ear canal - not on top of the actual ear. So, you push the earphone part into your ear and then the brace sits on the inner side of ear, not on top of the ear. Big difference. These fit nicely in this spot, find their resting spot easily, and there is no fussing around with getting them in a comfortable way. Was I shocked about the design? Yes. Does it now make perfect sense? Absolutely! These have some other cool things, like the back of the band (that would face traffic behind you) can illuminate with a light that gently blinks (not a strobe light) to give you a possibility cars might see you at night. It isn't going to light your way or anything, but in total darkness it may get someone's attention; when out jogging/walking and it is dark, anything is better than nothing. They are rated at 12 hours of run time between charges, and I found that was the minimum. I don't play them at a high volume level, so I guess if I did, maybe 12 hours is more accurate? The fact they are rechargeable so easily, was nice. And they rate the speed charge that with 5 minutes of charge, you get an hour of play - great if you were going out for a run/walk and forgot to charge them, 5 minutes for an hour. I did't stay out for an hour, but found that a fast charge did work well. IMPORTANT: In the box under the headphones is your micro USB cable BUT ALSO is a box with 2 other sized earphone adapters. If you have smaller or larger ear canal openings, you will want to know about these and not accidentally throw them out. A nice product, made by JBL and marketed using the Under Armor branding. The sound? Amazing. The ability to shed the noise of the outside world while being able to listen MY stuff and not everything around me was refreshing. Great job, nice product!

    Awesome workout headphones, so so for running

    This was my first go at a pair of "necklace/neckband style headphones, and JBL has obviously put some work into these headphones. Lots of nice features like a sweat resistant nanocoating, a built-in running light around the back of the neckband and extra comfortable silicone earpieces that did an excellent job of staying in my ears. The neckband provides a weighted and solid place to connect the earbuds to as well as a place for the microphone and controls. I found this to be a little unwieldy for running as it has a tendency to slap against your clavicle/neck as you run. Its almost like they need to be heavier to stay in place, but at the same time, I wouldn't want to wear them if they were indeed that weighty. This is too bad since the built-in light is a boon for runners. Other cons are the lack of a battery indicator that only tells you when the battery is low, and not what the battery status is at the time. Battery life seems to be pretty spot on the reported 12 hours, and the quick charge option of 5 min of charge for one hour of use was definitely appreciated and I've used it more than once. The provided silicone pads let you find the most comfortable fit for your ears and the combination of the in-ear buds and extra wings that extend up into your ear held them in place fairly well during activity and were comfortable for extended wearing times. Containing the controls and microphone in the flexible end of the neckband is a smart and the right design choice in my mind. Materials all feel solid and well made, you can feel the nano coating. The sound quality was surprisingly high, with bass reproduction amazing coming from these tiny drivers. The earbuds themselves are also magnetic so they can be worn as a sort of necklace when not in the ears, keeping them stowed. Overall these are well made and sound decent for the price range. JBL missed the mark a little bit for runners, in spite of the added features, but these don't necessarily have to be used strictly for running, Any outdoors activity or working out will put you in the target market for these headphones.

    Extremely comfortable and lightweight

    I’ve been using the JBL Under Armour Sport Flex headphones for over a week now. The headphones came nicely packaged in a well constructed box with a slide out foam insert The box and headphones should ship nicely without any damage since they are packaged so well. The box includes a USB charging cable, 2 additional sizes of ear tips and 1 enhancer without the wing tip. I didn’t like the way the extra ear tips were packaged, inside an envelope in a little box. They were flattened by the envelope and after sitting out for a day, did not revert to the original shape. Luckily the ear tips that came installed on the headphones were the perfect fit for me. Also included is a really handy mini instruction booklet, tiny print but it’s in color with pictures and is very easy to understand. These is no included carry case our pouch, which is disappointing. I like the lightweight design of the neckband. These are probably the most comfortable headphones I’ve ever used, both the neck band and ear tips. I could wear these for hours without discomfort. The adjustable flex zones, for the most part, just give you a tighter fit, which loosens as you work out. Please note that the instructions say not to bend them outward past the original position. The button position is good but I are somewhat stiff to press and require a little more precision. I find myself pressing the buttons with the tip of my fingernail. There is an LED strip light on the back of the neckband that has a few different modes and is great for evening running. The earbuds themselves do not wrap, tuck or retract. They are magnetic and cling to each other but I wish they stored better than leaving them hanging like that. The sound quality is very clean and clear however it lacks the bass I’m using to getting from other headphones in this price range. I think JBL may have sacrificed a bit on sound to deliver such a lightweight comfortable design. Honestly, if these headphones are only for your workouts, a lack of bass is probably okay.. But I wouldn’t recommend them as your all-day, general purpose headphones.

    The JBL Under Armour Flex headphones are what I have been wanting in sport headphones which is COMFORT. The JBL Flex eliminates the snagging that I would experience with my previous wireless headphones with the sleek, hardshell neckband that slips around the neck. If it’s too loose then with hardly any effort, you can make bend the neck arms so that there’s a tighter fit. I’m able to have a full rotation of my head without the consequence of snagging on the necklace that’s beneath my t-shirt during laps or when the simple wire would ‘stick’ to the back of my neck because of sweat or moisture. The earbuds on the Flex don’t pop out of my ears because of snagging or high impact movements. I also have to note that the Flex earbuds are a really secure fit that provides a deeper listening experience. During my laps, I like to listen to high energy music and even podcasts, the sound is rich which is something that one would get with higher end, casual headphones. I have to celebrate the range that the Flex has when it comes to distance. With my previous sport headphones, if my phone was below my waist, the audio would struggle to maintain a connection. With the JBL Flex, I’ve tested it out up to 25ft and there wasn’t any loss of sound or connection which means you’re not obligated to keep your device in an armband to maintain a connection. There’s an added bonus to the Flex headphones with the LED lights that make you visible for the evening runs/walks. This optional feature is activated with the press of a button. I’ve used the Flex headphones for phone calls a couple of times so far and there wasn’t any issue with the call quality. I was able to hear and be heard with the person I was talking to. The charging time for these is really efficient which is complemented by the fact that the USB charge port is easily accessible instead of trying to pry it open. It’s the little things that make you appreciate the product even more. I honestly cannot find anything negative to say about these headphones and I don’t think you will either.

    JBL Sport Flex earbuds did impress me with a great sound quality for the size. They do sound like a pair of big over-the-ear headphones with a very deep bass and perfectly crisp highs. Comfortable neckband can be adjusted to fit exactly around your neck so it does not bounce around when you exercise, it's very lightweight and you hardly feel it. Earbuds are made for perfect fit, lightweight but fit secure in the ear canal providing a good sound isolation. RUNSAFE is an interesting feature of these headphones - neck band has a set of white LEDs that glow around it and you can turn them just on or make blink, it supposed to make you visible for people or vehicles behind you, how good does it work? To me they are too dim to make any noticeable difference and they should have been red, not white, please look at the picture attached. Overall - it's an amazing set for an active person, very light, secure around the neck, if you want to talk to someone - just let earbud hang on the wire (it's not like you have to keep holding a true wireless earbud in your hand). Full charge (about 2 hours of charge time) should give you 12 hours of music. On the cons side: control buttons are a bit tough (but I guess that is to prevent accidental presses), RUNSAFE LEDs on the back can't beat a high visibility running clothes in my opinion (if you are to run after dark).

    JBL - Under Armour Sport Flex Wireless In-Ear Behind-The-Neck Headphones setup is quick and easy. I was able to connect my iPhone quickly using Bluetooth. I am wearing this headphones everyday as it was so much convenient while running / biking due to long battery life around 12 hours. The headphones feel good while wearing and well built. The design protect the headphones slipping around the neck while doing workouts. The ear-buds are magnetic and it is really cool design to keep them together while not using it. The buttons are very easy to use for play, pause and volume adjustments. Another great feature is RunSafe LED which allows you to configure three flashing modes while running in the dark. It supports Bluetooth 4.1 interface to enable simple pairing and wireless streaming with compatible devices. Supports HFP, HSP, A2DP and AVRCP Bluetooth profiles. The headphones are sweat-resistant to provide protection from sweat, so you can easily wear these headphones while working out. The sound quality is amazing and this headphone is very comfortable to wear and lightweight. The battery is great and providing close to 12 hours. I was able to charge quickly. I use this headphone all day during work and workout. It is one of the best headphone owned by me and another outstanding product from JBL.

    JBL - Under Armour Sport Flex Wireless

    One of the best features of the JBL UA sport flex headset is the safety light across the neck band that flashes to ensure you are visible to others while on a run or walk early in the morning or late in the evening. The headset itself is pretty comfortable to wear and is light enough to forget its even there. It includes a set of ear tips that fit snuggly in the ears and provides a decent seal for a quality sound. Another great feature of the headset is the ability to work for an hour on a 5 minute charge. An excellent feature when your headset dies mid flight while watching a movie and you can quickly charge it using a portable battery. The bluetooth pairs quickly and did not lose connection when running or cycling with the phone in the pocket or on the handlebar. On a full charge the headset lasts for around 12-14 hours of use. It uses a regular micro usb port to charge. These are sweat resistant and are ideal for workouts, running or cycling. I would assume they would be somewhat splash resistant as well. The earbuds are magnetic and store away pretty nicely and are out of the way when not in use. The music controls are right on the edge and much easier to use and provide tactical feedback when the buttons are pressed. These are a perfect pair of headphones for active users as well as travelers.

    Mediocre at best

    So I've been wearing these headphones for about 3 weeks. I have had many necklace style headphones in the past. I have worn the LG's with the retractable ear buds as well as many other types of this style. As for the UA/JBL's firstly what I like about them. They are by far the lightest I've warn. I work outside in the sun throwing chains over 50k lbs loads of steel. You know man's work and the do not get slippery when sweaty. The silicon part that helps keep them in place in you ear is soft and comfortable and really you cant even feel it. Lastly the quick charge is a life saver. I constantly run the battery out because I use them 14-16 hours a day. Both for music and talking. That being said. The reason why I gave these headphones such a low rating is for the following reasons. Firstly the buttons are flat with the necklace. So it makes it hard to differentiate what button is which. Also the buttons are really hard to press. You really have to get in there with a nail to press the button to answer a call. There is no way to check the battery. It will let you know when its low but that about the extent of it. The microphone as far as far as I can tell are not noise canceling. The unit disconnects from the phone randomly and for seemingly no reason. There is no button to reconnect without turning the headset off then on again. The ear buds are a little big. They make my ears sore after a couple hours or so. I will be returning them to best buy and getting another pair. Hope you found this review helpful.

    The JBL- Under Armour Sports Flex Wireless headphones are the go to pair for me when I go running now. They are incredibly comfortable and fit very snug in my ear. I don't have to worry about them falling out and I sweat a lot and they still don't fall out of my ear. It is also worth noting that they are IPX5 certified and have advanced nano coating which Under Armour suggests gives it extreme protection against sweat which is really great for me. The sound quality is also great which I was surprised by. The bass is surprisingly punchy and they get very loud which I love for indoor treadmill runs. The neckband isn't just a regular neckband with these headphones as they also have an LED light that has three strobe functions for when you are outdoors at night and want to be more visible. It is noticeable from a distance and I always have it on when I'm running outdoors at night. The only knock I have on the headphones is that they feel very cheap. The buttons for volume and playback are difficult to press at times and the neckband does not feel very sturdy but that's where the FLEX comes in. They are able to bend to so that they fit your neck. I do like that they can do that but the neckband still moves around when playing basketball which isn't a big deal because it's easily fixed. Overall, the great sound and comfort of these headphones are what do it justice for me. The battery life is also top notch at 12 hours and can give you 1 hour of music with just a 5 minute charge! I definitely recommend this pair of headphones and they will be difficult to replace for my workouts and runs.

    Just had a nice jog today outside. Often with headphones I can hear outside cars driving by or I fear that I won’t be able to hear them. The neck light came in handy this evening and it’s subtle so I don’t feel ridiculous with bright green or red light blinking like those bicycles. I was pleased to see my earphones came with a subscription to MapMyRun which is Under Armour’s application for running. It is such a cool app because you can basically treat it like a social network like others. I saw which friends had the app and how they compared in my running. Charging the earphones was easy and fast. I think I charged them for five minutes and had them work for over an hour. Aesthetically they are sharp looking as well. Nice grey color and the earphones have a magnet in them so you can clasp them together to create a necklace when they aren’t hanging in your ear. JBL’s sound carries over to this joint venture with UA and it paid off. I was nervous about it being a gimmicky partnership but over all these are a good set of earphones for runner or athlete who might be new to running or working out!
