Customer Ratings & Reviews

I use these with my tablet while using my exercise bike or relaxing on the couch. I've had issues in the past with behind the neck headsets being irritating (felt weird) and it took awhile to get used to the style. But these were super comfortable out of the box. Battery life all of the 12 hours advertised; granted I'm not cranking them up and I turn them off when I'm not using them. All-in-all, I'm very happy with these.

These JBL UA Sport Flex headphones are a very good set of headpohones. They have a good sound to them. Not quite the JBL signature sound I was expecting, but above average. Battery life is great I used them all weekend long doing yard work, working on my truck, and chores around the house, I've never got the the point the battery needed to be recharged. I did make sure they were fully charged before using them. I mostly listened to podcasts, but I did listen to some music, and they sounded pretty good. The earbuds have magnets on the back of them, so you can connect them and not have to worry about them swinging around when you're doing tasks and don't have them in your ear. There's also a flashing LED bar on the back of the Flex band that can be set to three different patterns, or to off. I'm guessing this is for safety when running at night. I would love to say they are great, and give them 5*'s, but there a few things I found annoying or not what I expected. I've already mentioned the sound. The Bluetooth range on this set is very small. I found simply walking to the next room was enough to start getting garbled out of range sound. I had to have my phone in my pocket to combat this. Another thing is the "Flex" band does not stay centered very well if you are just walking around or doing something other than running. I'm no runner, but I tried running around, and that movement tends to keep the band centered, so that's something you may want to consider if you are not a runner. It's really annoying constantly re-centering the band.

The JBL - Under Armour Sport Flex Wireless headphones are perfect for me and all of my regular activities. I can use them while running and exercising or while in the car on a phone call. The sound quality is excellent and they are comfortable for extended periods of use. I would recommend these to everyone.

I generally have good luck with JBL ear buds. They just always seem to fit my ears without any adjustments, and they sound good. These are no exception. Other brands sound better at higher price points, but these sound good. The "flex" points are just unecessary. I have not figured out what exactly is intended for this feature, as no matter how you bend them, they still "walk" around your neck if you run or do any type of cardio. The flex for me acts more like spring loaded hinges on a pair of glasses, that keep you from breaking them when taking them off. For that, the Flex feature makes sense. The wires do not retract as some other brands do, which leaves them dangling when not in your ears, but they are magnetized, so they stick together instead of falling free and swinging over a shoulder. Controls are intuitive and simple, and since these are becoming very uniform across these products, there'e really no explanation required. Pairing is easy, and a blue light indicates the status. One thing I do like that is not just a gimmick is the LED light that has several different patterns to put in place while running in dusk or dark. The light is bright and obvious to passersby, and an excellent nod to safety--while no drain on the battery! The battery life is outstanding and lives up to 12 hours as advertised.

The JBL Under Armour Sport Flex Headphones are an excellent pair of headphones for anyone looking for headphones that can keep up with their active lifestyle. With adjustable tension on the neckband which allows you to adjust the tension based on your activity. The audio is amazingly crisp and clear and has decent amount of bass for headphones this small. My only complaint is that while the neckband is adjustable the back can seem slightly tight if you have a larger neck. It is only slightly noticeable to me due to my neck size and tendency to not like having anything around my neck. If these are not issues for you it will not even be noticeable to you. If you are looking for an excellent pair of sports headphones I would highly recommend these pair for you.

I was a little doubtful about buying them because I do love good sound and good bass. Well I'm glad I got them because the sound is great and the bass is great too. They're also very comfortable around your neck and inside your ears. I wish the magnets were stronger but that's not a deal breaker. This are great for every day use and for the gym, they won't fall off your ears and you will forget that you have them on. I'm very satisfied with them and I think the price is reasonable.

The flexible neckband on these headphones is such a great feature! It makes them very comfortable and easy to fit around any size neck. The ear buds stay in place with no issues and the sound quality is excellent.

These headphones are the best! I wear them on my commute to work and also wear them on my runs. They're super easy to connect and the battery life is awesome (I barely ever charge it). The earbuds stay put even on the longer, sweatier runs so you don't have to worry about readjusting them. Sound quality is great too as you'd expect from JBL and calls are clear. Bonus points on the MapMyRun membership! I love these so much I'm going to get a pair for my husband too.

These are great for running in the dark because they glow. The battery life is excellent. The negative is the rub a little when your running. I feel there are better running headphones for the money out there.

Out of the box, I plugged the headphones in via the provided USB charger, and charges the headphones completely. Turning them on. Well, honestly that could have been made clearer in the instructions. Press and hold the PLAY button for two seconds turns them on and puts the headphones into pairing mode. I gave them a listen, and while they are very functional, they lack any real bass response. I get it - it's hard to reproduce low frequency with tiny drivers, but I felt as if I were listening to AM radio.

I have been searching for wireless headphones that will stay in my ears and not bounce around while running. I was skeptical that the neck ring of these headphones would fit the bill. I was very wrong. These headphones stay in my ears an the neck ring does not bounce even when running at 7 min per mile. The sound through these headphones are excellent as well and it blocks out outside noise as well. I think I have found my new bluetooth headphones!

This are similar to all the other neckband earphones out there except they don't have anyplace to store the Earbuds but they have magnets on both to stick to each other. They also have ear hooks so they stay in place which makes them good for active stuff. They also sound fairly decent as well considering they are bluetooth

Everything about these headphones were perfect until i put my phone in my pockect & found out that the Bluetooth is very weak. After 2 feet it tends to disconnect. THE BATTERY LASTS ALMOST 6 HOURS ON FULL BLAST THESE DO NOT LAST 12 HOURS AS ADVERTISED. BUT SKULL CANDY DOES BUT THESE HAVE BETTER ACOUSTICS & BASS WITH PERFECT HIGHS & LOWS SIMULTANEOUSLY. THEY DO HANDLE LOUDS OF SWEAT WELL WHICH IS PERFECT IT CHARGES FAST. I USE THIS FOR WORK ( GENERAL LABORER 2 TIMES.) BUT BECAUSE I DON'T LIKE THE CONNECTION INTERRUPTION / INTERFERENCE AFTER 2 feet it has to go. I have given these a solid 10 days. I mean really banging them out

Let me first say the design on this headset is flawless But the volume and call clarity kinda fell short. I was in park and kept getting the dreaded can you hear me cause I cant hear you doing my workout. I wanted to love it but I couldn't.

There seems to be a major flaw with these that they constantly drop connection. I already got mines replaced twice and they all do the same thing. when connected they sound great but the constant disconnects are truly annoying. not even my cheap QCY earbuds have this issue and those only cost me $20. if not for the constant disconnects I would rate these 10/10.

VERY POOR BLUETOOTH SIGNAL!! You can't use it even if your cellphone is in your back pocket. If you go away your cellphone for 4 feet, it already cuts. But the sound is really good. Overall, if you keep your cellphone near the headphone, you'll be ok, but if you need to get away from your phone few times a day, this headphone is not for you.

These are the first behind-the-neck headphones I've run with and can say they are awesome. Really comfortable and secure, didn't move around during runs. The sound is fantastic with good battery life. Highly recommend!!!

I love these headphones! They connect easily, provide reminders when battery is running low, and the running light is especially cool! The fins keep them comfortably stable in my ears even when I'm rockin' my ab workout!

I was a little weary to try wireless headphones but these were a perfect choice. Couldn’t be happier. Great sound, no cord, long battery life. Life is good.

Very comfortable, good ear fit. Don't slip out during hard workouts. Great sound quality too!
