The original set had a failed power button, so I could not turn on or pair with a phone

I had a problem with them not powering on and Avantree support was awesome and had a hassle free replacement via the warranty

The only downside is that some bluetooth transmitters apparently don't have enough power to give these much range

Power/Play/Pause button used for answering/rejecting calls, redialing (double click), and accessing a voice assistant (longpress; a bit touchy since holding the button just a moment longer will cause the headphones to power off instead); volume up/skip forward button; volume down/skip backward button; and an ANC on/off toggle button that can be used to turn the function on at any time (provided there's enough

One other minor gripe is that the power on, off, and connected messages are too loud for me

I have used mine every day to watch movies and listen to music but after one month it got the static white noise when power it on but the customer services promptly to exchange the new one according to their guarantee without hassles
