About 3 weeks ago I picked up 2 new AP7 Pros and so far so good from a performance perspective.
The only issue I’m encountering is I’ve noticed that there’s a slight buzzing that they emit that can be quite noticeable.
I have one of them mounted in a room of our townhome and I’m in there quite frequently. Anytime I don’t have my IEMs in it drives me nuts. I really love the unit, but this has been tough to deal with.
