What should I do if the audio quality is poor, and crackling noise can be heard?
a) Check that your connected device is nearby, and there's no wireless interference or obstructions between the earbuds and your device. Clear away any potential ireless Interference Devices and avoid Physical Objects. (Some wireless devices in the vicinity of the transmitter may negatively affect the range.

c) Try to reset the earbuds.
