Sennheiser PXC 550-II Wireless Active Noise-Canceling Over-Ear 'All-Day' Headphones

These are great headphones and I absolutely love them. The only reason I gave a 4 star rating instead of 5 is due to comfort. They seem to squeeze my head and ears and after a few hours, I have to take a break. But the sound quality is very good and that's why I purchased them. After I downloaded the Sennheiser Smart Control app, I can now adjust the music to deliver that bass the way I like it. Although the ANC might not be the best there is, it is still very good. I can't see any music lover that buy's these going wrong. Hope this helps.
