Sennheiser HD 6XX, Audioengine HD3, EPOS PC38x, Bose QC45, Steelseries NOVA PRO wireless with Burson Soloist 3XP

My composer has had issues and i’ve had to send it back to have a replacement sent out. My only complaint (short of the defective unit) is the response time from Support. I only got response if i asked for it. Almost always reactive: not pro-active.
