Background noise problem with BOSE QC15
Problem: Constent annoying background noise when not playing audio. It is gone when any audio is playing.
Very tricky, needs 3 conditions
1. Bose QC15 with HI Gain Switch (earpod ok)
2. Charger plugged into Note 3
3. No audio playing
It seems that HI Gain is somehow too sensitive, but it never happen on iPod Nano 7th Gen, Nexus 7 or any other of my devices.
The noise start when Usb cable (both 2.0 and 3.0 will do) conduct any part inside the port, no need to plug into position.
Tried apple earpod, no noise.
So what shoud the conclusion be based on these confused result?
