    Great Set of Workout Headphones

    I received the JBL Under Armour Sport Flex Wireless In-Ear Behind-the-Neck Headphones about a week ago and so far, I have been impressed. The headphones are packaged nicely in a foam insert inside of a sturdy box. They come with a charge cord, 3 different sized ear inserts, and a detailed instruction booklet. After the unboxing, the headphones were fully charged within 30 minutes. They were easy to pair with my iPhone via the Bluetooth connection. The neckband can be adjusted to fit securely on your neck. The earbuds fit very well in my ears and did not fall out during an hour long, intense CrossFit-style workout. The control buttons are located in easy-to-use locations on the neckband. The headphones are lightweight and sound great. After six hours of use, I have yet to run the battery completely down as they will hold about a 12-hour charge which is more than my phone will do. When not in your ears, the earbuds are magnetic and can be clipped together to keep from bouncing around on your neck…a nice addition. Another well-thought-out addition is a flashing LED light on the back of the headband that can be turned on to help make sure you are seen while jogging at night. Great design overall. Lightweight, comfortable, and sound great...I can honestly say that these are the best set of workout headphones that I have owned. Highly recommended!!

    I have been using these for about a week, great headphones. I have a 18.5" neck so I really appreciate the flex zone to change up the size. I can make them loose when just bumbling around and tighten them up when I am working out etc... Sound quality is good near great. I have read other reviews concerned about bass. The produce enough bass to sound good. If you want to thump buy a pair of over the ear headphones or spend triple this on another product. For even the above average listener I think these will fit the bill. The other feature I think sets these apart is the LED light on the back of the neck band. Pretty useful feature for anything you may do at dusk or after. I don't run so I rode my bike, again great feature. Battery life is listed at 12 hours, from what I can tell I would have gotten that at a minimum, possibly less if you use the LED light more. My only complaint about the unit is the buttons. They are small and the placement makes them mildly difficult to use. Having XXL hands probably has something to do with that but still I have other units that are more easily operated. This downfall however is not enough to lower the rating or not recommend just good information to know. All things considered I would recommend at this price point for sound quality and other features.

    Best I have owned

    I will open up by saying I have tested many in-ear headphones. These are my favorite to date. The two main reasons; they stay in my ears, and they have nice bass. I simply thought I would never find an in-ear headphone that had decent bass and had almost resigned to that. JBL quality did not disappoint. I will say, when you put these in, the rest of the world is shut out. The earbuds really seal any outside noise, almost too good, as I have to look at someone to see if they are trying to talk to me. The only complaint I would have (albeit minor), are the control buttons. I would have liked an easier textile feel to them and a little easier to press.The buttons are hard to see and feel. Bluetooth range is just okay as well, don't walk too far away from the device. This is not a real problem for me as my phone is usually on my side. Battery life is very good as well. Oh, side note, the instructions are printed way too small. get out the magnifier! For the money, they spent on the packaging, not sure why they print the instructions on pages the size of a business card. Pros: Great Sound Quality Fit Battery life Safety light for night runners/walkers Cons; Textile of buttons Bluetooth range Instructions hard to read Overall a these are a great buy. I would highly recommend.

    Overall these aren't a bad pair of headphones, just not great. They are light and have enough battery to carry you through a few work outs with the ability to bend the headphones in a bit to stay on if you tend to bounce around while exercising. It does have one feature which isn't bad, the Runsafe LED light that will produce a glow from an LED light on the neckband. I'm sure it does help but means you have to keep this outside of any collar and hair to get the full effect. Not sure if they are bright enough to really make a difference seemed a bit dim when I tested at Twilight to do a lot of good, but anything is better then nothing. The sound was what I expected from JBL, it was good, just didn't blow me away compared to others, but didn't sound horrible either. What I don't like is the fact they give you a short charging cable. That's fine if I plug in on a desk, but if I want to hand on the door near my keys so I have them for my twilight walks, not handy at all and wish all manufacturers would include longer cables and not try to skimp. Overall a decent design for sweatproof headphones. A couple of neat eyes likes LED lights to help you stay safe and bendable neck adjustment, with a decent battery (easy to carry for a few days of walking) and light. If those few items above seem what you are looking for then these are the headphones for you. For a teen athlete I think these would be perfect or if you want something to help keep you safe on the side of the road at dusk, again have a look.
