Can barely hear these compared to my wired earbuds. No bass whatsoever. Tried them on multiple phones. Don’t bother.

Great headphones

I got these headphones for Christmas they are the best headphones I have used to date and I have had beats Pre and post apple, apples AirPods, jay birds, and skullcandy to name a few these outperform all those. I mixed and matched the ear pieces and found a perfect fit. The sound is awesome and the technology makes it easy to know when someone is trying to talk to you. The case is big but the time between charges makes it worth it
I would recommend this to a friend!

Mixed feeling because of the button functionality.

These headphones have a great feel and sound to them. They could be greatly improved by having any sort of volume control on them. Without it you still end up screwing around with your phone when on a run, which is the point of being wireless. The left ear bud having one click mute and two click adaptive listening is jenky IMHO. When indoors I end up leaving the left one out to hear someone and just use the right one to control the pause and next song button. I have other wireless headphones that from a functionality perspective I like better. They fit awesome for sure. The size is great, the sound is good. Maybe the next evolution will improve. I would wait before buying another pair.

Great fit and sound
on June 5, 2019

I was looking for a replacement for my Bose wireless sound sport earbuds which had great sound, but proved unreliable (after some time they stop working which I think is due to sweat / moisture during workout and this was the same with multiple replacements).
I read reviews (user reviews are best as they give the real experience) for most leading true wireless earbuds and most appear to have connectivity issues / dropouts between left and right.
Then I came across under armour true wireless. On the basis of the reviews (and good YouTube ones as well) I went for these. I have used them for over a month now and can say that overall they are great, especially for sport / running (the main purpose I bought them).
Positives and negatives are below. Positives far outweigh the negatives (which are bearable but could be improved).
Positives:
- sound (for the type of earbud it’s great with good bass and overall quality. I noticed that sound improves depending how good you fit it and seal within the ear. The sound is not as good as good around the ear headphones, but for this type it’s about 8.5/10).
- ambience noise etc (you don’t hear anything outside in normal mode, but there is an ambient mode if you want to hear around you).
- great fit (they never feel like they are coming out and they have different buds for S/M/L).
- water resistance rating is better than most other brands (essential for longevity if using for sports).
- wireless / connectivity is great (I have hardly had any issues / dropouts at all).
- battery life (4-5 hours comfortably plus the charging case means you don’t have to charge with external power for a long time).
- wireless talking (I could hear the other person and they could hear me clearly with minimal background noise when I was in a noisy airport).
Negatives:
- sound lag between audio and video (this isn’t much of an issue for me as I don’t primarily use for watching video etc, however there is a slight delay (it’s almost bearable but noticeable), maybe because of Bluetooth version, hence if your primary aim is for sports or audio then you will have no issue. If primary use is video then you may want to consider something else).
- lack of volume control (you have to adjust volume from your device which is ok most times but can be a pain).
- no rewind / previous track option (only play, pause, skip forward).
- buttons (you have to press in quite firmly i.e. for play/pause etc, which pushes in to the ear. It would be better to have based on touch tap.

Stopped working

They stopped pairing with my iPhone after 2 uses which was really frustrating. I sat for about an hour with them fully charged, trying to manually sync them and they just wouldn't work. I had to return them and get my money back.
I'm normally a supporter of Under Armour and I like the brand, but for the price I paid on these, I was expecting to get more than 3 weeks of use out of them. I was extremely disappointed and will buy another brand.
