I hear crackling noises

Bluetooth is a radio technology, which means it is sensitive to objects between the headset and the connected device. It is designed for the headset and the connected device to be used within 10 meters (33 feet) of each other, with no major objects in the way (walls, etc.).

The music player starts playing when connecting to the headset, you experience connect/disconnect issues or the headset has short battery life.

Pair your headset again to the device in order to avoid this behavior.

1. Ensure that the headset is on. If the music streaming has started, turn the music player on the phone off.
2. Press and hold the answer/end button for approx. 5 sec. until the light turns to solid blue.
3. Continue to press and hold the answer/end button until the solid blue light turns off
4. Continue to press and hold until a solid purple light turns on. Go through the regular steps in pairing the headset to a Bluetooth device.
