Half Dead
My initial assessment on these ear buds was that they were exceptional. The fit is great, battery life is good and they function well in the gym. However, after about 3 months the talk-through function stopped working and the mic was no longer working. This didn’t bother me too much because I avoid calls and talking on the phone while working out. Fast forward to about 9 months and one of the ear buds has stopped working at all. It appears that it doesn’t charge anymore. I have cleaned the contacts on the charger and the ear bud and now change. Unfortunately, my warranty ran out about 45 days ago. Considering what these cost I had expected at least 2 years of service.

Charging Issues x 2
I received my first set of these at New Years 2020. They worked for 2 months and then the left earbud stopped charging/would not hold any charge at all. After fighting with customer service for a month I eventually got a replacement.
The replacement arrived and worked for a month until, you guessed it, the left earbud stopped charging. This is ridiculous that I'm starting yet another mission to get another replacement. I'd imagine the Rock would be embarressed if he knew he put his name to this!
What makes it more frustrating is that they are in fact excellent when working!!
Wish me luck for 3rd time lucky!

Good for music and activity, phone call feature with microphone is terrible
Good for listening to music during workouts. Style of the product is nice. For the money spent though, I am very dissapointed that no one can hear me on calls.
The incoming call audio comes through fine but my voice isn't being picked up by the mic at all, even when holding the mic ear bud super close to my mouth. Hopefully support can offer some advice on this...
I would rather you have cut out the phone reception feature entirely since it doesn't seem to work and knock $50 or so off the price.
Satisfied with the product for listening to music coupled with strenuous physical activity but shouldn't have to disconnect to take phone calls, overpriced to not have stable functionality in that regard.

Not a gimmick! The Best Wireless for Workouts!
Six Month Quality Review:
1. High-quality sound - JBL!
2. Stays put - Amazing fit!
3. Waterproof- Sweatproof!
4. Under Armour + The Rock - Perfect Partnership!
I am very happy with this product. I have used these headphones for every workout for the last six months. I continue to be amazed by the sound quality and durability of these buds! Wattage-wise, I "wised" up to the simple fact that I do not need high wattage channeling directly into my ear canal! These buds find the perfect balance to providing enough power output to drive through that next heavy set of bench presses without making your ears hurt! Great product, great product sponsor in Mr. Dwayne "The Rock" Johnson!

Earbuds are great but the case is just ok.
I bought these for my husband who’s job requires long hours of walking. So far the earbuds are fantastic they do exactly what they promised they would, they are comfortable up to a point. His ears do start to hurt after a while but that happens with all earbuds for him. My only problem is the carabiner attachment, after wearing the case on his belt loop for about 3 days the silicone piece snapped from the case. The product is still fully functional but I’m really disappointed with how quickly the case broke.

Product Q&A
Are they fully submersible? Can you swim with them?
They are fully submersible, but swimming and listening to music with them won't work. Bluetooth cannot transmit through water, so as soon as the earbud goes under water, it will lose connectivity with your phone.

Volume Control
Is there a way to adjust the volume other than the device it’s connected to?
No, there is no volume control on the earbuds

Can u use it for phone calls as well?
Also can u have one ear bud and have one charging?
Does both of the headphone has a built in mic or one of them only?
No you cannot. Infact I bought them and can hear the person on the call but they cannot hear me at all. I’ve to take the right earbud off and bring it close to my mouth for them to hear me which is ridiculous

Is it ok to use while swimming, since it's waterproof?
A rating of IPX7 means that the product can be immersed in water for a maximum of 30 minutes at a depth between 15cm to 1m.

Do they work independently of one another? Can I switch/talk through each earbud?
Hello. I have the regular Under Armour version of these.
The right one will work independently but the left one will not.
To confirm this I called JBL directly and they put me thought to one of the product engineers.
Not a deal breaker for me, but it would be awesome.
Hope this helps.

Will these pause what you're listening to if you take an ear bud out and auto resume when you put it back in?
The UA True Wireless Flash Project Rock Edition can be paused, but does not have song recognition. If you turn the headphones off by putting them back into the charging case, you will not be able to resume the song you were once paused at.

Can you used them in the sauna?
Per JBL's warning they should not be exposed to anything over 140 °F (60°C) due to the lithium batteries.
So as long as you stay under that range you should be fine.

Do these have an integrated heart rate monitor?
To the best of my knowledge, there is no heart rate monitor with this device. UA does feature several health apps that give an approximation of what your rate is based upon your age, weight, etc... and the type of exercise you are doing.
