Also, when you turn your head to the left, they start to crackle and lose connection

If you set your device on one side of a wall and walk to the other side, you’ll experience a crackling, in and out, bad connection

The only issue is that it will lose the connection to the device if you are separated from it at a short distance.

Phone calls sounded painfully robotic, audio would cut or with my phone in my left back pocket 3 feet from the headset, if my hand went anywhere near it out would cut out completely and sometimes lose connection.
