I Hear Cracking / Popping / Clicking / Static / Humming Noise From My Headphones. What do I do?

This could be caused by connection issues and can usually be fixed through a simple factory reset, here is how you do a reset of it:

After powering it on, press and hold the volume + and - buttons simultaneously for about 5 seconds until the LED turns PINK, the headphones should then go into pairing mode and the LED will alternate between flashing RED & BLUE. The voice prompt will also say "Pairing". 

If factory reset doesn’t solve the issue, please provide the following information to help us troubleshoot:
1. Do you hear the noise from both sides? Or just one side?
2. Does it only happen while the ANC is on?
3. Did you receive it like this or was it fine until recently?
4. How exactly is the noise presenting? Is it static like, popping sound or clicking noise? Persistent or intermittent?
5. What are you using the headphones with? Phone? PC?
6. Did you notice any particular “trigger” for this issue?
7. Is it possible to record an audio clip of the noise to show our engineers?
