If these headphones worked better, I would give them another chance in terms of battery life. You are not very good. I always felt like they would fall out of my ears despite trying all adapter sizes. Bluetooth didn't control the volume on my iPhone while I was at work. This means you have two completely independent ways to increase/decrease the volume; Phone controls and controls on the headset itself. For the price, full Bluetooth control should be properly and fully implemented. The neck strap is annoying, I could never decide whether to wear it inside or outside the shirt collar. Storing headphones on the ends of a necklace is totally impractical and can't keep them there. You wouldn't think it matters much until you find the buds hanging loose and tangled in whatever is available in your backpack. The battery issue was the last straw. After fully charging the headphones in my office, using them for an hour on the train home, turning them off and leaving them in my backpack the next day, I found them dead. It happened twice, two days in a row. Last straw. It was too much hassle so I sent them back. You can easily try them if you want; Returning items through Revain is not a problem, but I personally don't recommend them.
