Rated 5 out of 5 by from Great workout headphones!!! I debated getting these for a while to use at the gym. I saw them go on sale and finally got them! Good price and free 2 day shipping. I got them and couldn't be happier! They stay on while working out even running and doing push ups. The sound quality is great and the talk thru feature is awesome! They even came with a cord so I can plug into my controller and use with my PS4 as well! Very happy - great product!

Rated 5 out of 5 by from Everything about it I bought these headphones a few weeks ago and they are awesome. The push button on the ear of the headphones is very handy when talking. Sounds is good, bass is good.

Rated 5 out of 5 by from Charging issue I have owned these for 4 months now and couldn't be happier but they are now giving me problems. I use them onc, for an hour, after being fully charge, and then they don't switch on again unless I recharge again. The recharging is also taking a lot longer than usual. Can somebody please help me as this is very annoying.

Rated 5 out of 5 by from Great for the gym! I really love this product, especially for working out and phone calls. But they hurt my head and ears if I use them for several hours like I normally would with my headsets. Easy to wash the ear pads, but they are hard to put back on after washing them. Great sound! And talk-through is extremely handy!

How much does this weigh? &nbsp;It stays on while running?

Asked by: Rusy24
Sorry, I just weighed them, and they weigh 245 gram, not 788! 788 may be the shipping weight, but it would really be a problem on your head.

Does anyone jog with these? Do they stay on good?

Asked by: klwalker2283
I jog with them and they stay on very well. You'll have full range of motion with your head when jogging. I feel like people are judging me while I have them on, but I really don't care. They aren't invisible by any means, but the sound is good and they stay put while I run. I've also ran with them on over a stocking cap and it is very comfortable too. You can also take phone calls on them with the push of a button. Skipping songs is easy. I don't like using the modified sound option to hear outside noises, because it makes too much a wind tunnel sound. I'd recommend them for running.

What is the difference between these and the project rock headphones?

Asked by: Stefano
Hi! I own a Project Rock Wireless and the only difference is the Project Rock Branding (Brahma Bull on the sides and on the case) and of course the price.

What is the diameter of the ear coverings of the headphones? Do they cover around the ears fully?

Asked by: Tiny traveller
Hi, and thank you for your interest! The Under Armour Sport Wireless Train is an on-ear model, not over-ear. This means that the ear pads rest on the ear lobes, not around them. The washable pads are soft but firm, and very comfortable to wear. Outer diameter is approx. 6.5 cm, inner diameter of the hole is approx. 3.5 cm.

Why would I want to purchase the Rock edition over the UA version if they're so similar?

Asked by: CerTac
Because you are a Rock fan, and you want the world to know it. Also, the Rock version looks tougher. Please note that the Rock version is USA only.
