    Great For Work-Outs!

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    5 minute charge feature. From dead battery to charged for 1 hour workout in 5minutes !!!!! Light weight and comfortable. Simple to use/learn controls. I use for HIIT training, weight room, and long runs primarily... some video watching and music at my computer as well. Can’t beat the price/feature value. Did I mention 5 minutes to charge.... I can’t count the number of workouts that have been saved by this feature.

    Constantly Disconnects

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Purchase these headphones a few days back and I'm already returning due to the poor bluetooth connection. If I were to stop playing media through the headphones for a few minutes, the headphones automatically disconnect and I would have to power them off and back on to reconnect every time. My last pair of LG Tone would stay connected the entire time that they were on.

    Terrible terrible heaphones

    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’m tired of having to wear over the head full ear cup headphones to drown out sounds at the gym. These were a great solution and are super comfortable!

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Disconnects after only a few min,, No buzz if disconnected, clumsy headphones just dangling there, no place to put them, no retraction etc. small buttons, almost have to use your fingernails to turn off/on disconnects if the phone is in your pocket! hard to reconnect, sometimes takes several restarts ONLY redeeming quality is voice calls are fairly clear

    Do not bother wasting your money on these headphones. They are uncomfortable and the sound quality is awful. The Bluetooth function is not very clear. with the new line of products out now days. These headphones are obsolete and should be $20.

    Complete garbage especially at the pricepoint

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This is a laughable attempt at replacing the LG tones. Sound quality is terrible with almost no bass, the mic stops working about 5 minutes into every phone call, the buttons would be great if they were even remotely useable while you are wearing them, and they are constantly trying to fall off my neck. It has large buttons that have a very small press point and they are extremely stiff. Since best buy no longer carries the tones I tried these as a replacement and have decided I will be purchasing lg tones elsewhere. Also the box says 12 hours of use... I got 6 with a full charge the first time I used them. Bought and returned within a day.

    totally miss leading about using for phone calls

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I use headsets like this for phone calls as I am a computer tech and need my hands free. I like using the sport ones cause I work in a warehouse in Texas and during the summer I sweat a lot. So I bought these and have had them for a week and they keep disconnecting from my phone. Called support today and they said yes they will do this because it saves the battery. So these are meant to have something playing through them all the time, even though it says they can be used for phone calls, I say not really. So I will be taking these back and getting something that will really work for calls. I hope this helps other people.
