Are one of those features an eq or way to contol bass and treble? Right now I'm on the fence as to send mine back or not based on that. Not everybody listens to classical or jazz or pop etc. We all have different rooms and music taste and right now the air seems too tuned for mids and vocals like a flat eq. And yes I got my replacement earlier today.
