Alright I wanted to provide a good review for these headphones. I work out almost every day and especially on the treadmill/elliptical. I use neckband style headsets like the lg tone pros usually but obviously they're not really meant for exercise. I own a few bt headsets and figured I'd try these as well. I like the wraparound style as I don't have to worry about bouncing. Came in a minimal type box which is the headset( mines blue), a microusb cable for charging, and ear tips s, m, and large. It was easy to pair, is bt 4.1, and they're in ear type earbuds. Rated for 8 hours and I'd say it'll get that easily. I used them everyday and at the end of the week did I get the notification that the battery was getting low. It lasts longer than my lg. The sound was good, louder than my lg and my jbl, and it held up just fine to sweat. Lol I even rinsed them quickly with no problems. Range is good, about 30 feet. I had no issue walking around while my iPhone stayed put charging. I've been impressed by the headset. It's still working perfectly and I've no doubt its benefit to me. If you exercise and don't want to spend a fortune, I'd suggest looking into these. Any questions let me know.
