I bought one of these last time they were up. I may have a defective unit, but this is what I’ve noticed.
The battery life is wonky. I may get 8 hours on a full charge, or only 2 hours.
It won’t always shut off when the switch is tuened to “off”.
The ear buds are fairly comfortable.
With that, the sound quality isn’t bad when it works.
Oh no! If you think that you got a defective headset, please contact customer service. They may be able to help.
