Input: If I had written this review when I first bought the headphones it would be an all 5 star review. These headphones sound and work great. That being said now that I’ve had them for some time and haven’t really used them very hard. Just mainly a few hours a week. The battery life has dropped pretty low, I’m lucky if I get two hours out of them and it takes a long time to charge them back to full. A lot of times I use one headphone at work and when the battery dies now I basically can’t use it again the same work day.

Awesome headphones, but battery degraded over time.
