I have no idea how they work since they never held a charge while I had them so I returned them.

Does not work with the app from JLab

battery life

Wouldn't purchase this again, stop working, won't charge!

Battery life very short. Power and connect to Bluetooth don’t work for minutes at a time. Poor quality

battery was good for 3 months. Now it dies in 10 minutes after charging for 8 hours. Don't waste your money

Came in and worked as advertised, actually I REALLY liked them. Decent sound quality, long battery life. But then maybe a week or two after I first started using them the battery life tanked down to 45 minutes max no matter how long it was charged.

I had these headphones for 1 month before the right ear stopped working. Not worth it for the cost. I’m very disappointed.

Liked them a lot initially. Still, after less than a year, the buttons are collapsed, can’t change up volume, hard to turn on / off.

Overall, I can only give 2 stars because of the short battery life, it says more than 25 hours, however, the one I received does not last for my commute (roughly 3-hour round trip). Other than that, the sound quality is excellent.
