S1 Pro buzzing noise

My S1 Pro has started making a buzzing noise in the treble frequency. If I turn the treble all the way down it almost goes away. If the treble is turned up it is very noticeable. The volume is at 50%. The problem is there plugged in or battery.

Hello Ciccelli,


The S1 Pro carries a 2 year warranty.  I would contact Bose support to determine what the next steps should be.
