Both my ULT Wear and WH-CH720N occasionally produce a faint high-pitched noise at varying tones after any sound has been played and the headphones become completely silent. The noise disappears as soon as audio starts playing again.

This issue does not happen all the time; it only occurs occasionally. It only happens when both Active Noise Cancellation (ANC) and Ambient Sound mode are turned off.

My WH-CH720N headphones are approximately 7 months old, and my ULT Wear headphones are about 3 weeks old. I didn't notice the sound on the CH720N until I noticed it on the ULT Wear.
