I'm getting a high pitch whine when plugging in my Koss KSC75's in the Moto G5. Not when fully plugged in, only halfway.
Your headphones are designed to be fully plugged in, not halfway. If you are only plugging in halfway, you are likely to get all kinds of interference, static, and other unwelcome behavior.
Why are you only plugging in haflway?
