These were great Hi-Res headphones, however unfortunately I didn't get to listen to many hours of wireless as these had charging problems on arrival, leading to a limited time using them with wireless connectivity. Via wired connection these were quite good albiet a bit too tight on my head. Pros - Awesome wired sound Cons - DOA unit, had to return - Bit tight for those with bigger house. Replaced with HD560s's after I realized how much I loved Hi-Res. Sennheiser HD560's are 5/5
