"Good sound but very uncomfortable"3.5 starson by freshnet
Pros: The sound quality is excellent compared to other ear bud headphones, including others in the Sennheiser range such as the CX, which I also have. The volume range is better as well. There are rubber as well as foam earpiece covers included
Cons: These are incredibly uncomfortable! The earpieces are made of hard plastic, and are too large to fit comfortably in the ears even with no covers on. Once the covers are on, I can only wear them for a few minutes before the pain is too much!
