I bought these expecting an incredibly great product, well worth the price. For the most part, that's what I got. They produce a very crisp, clear sound, and the bass sounds very powerful, without going overboard. However, they're so tight on my head, no matter how many times I have tried to stretch them out,(&I have a small head so I can't imagine what it's like for people with larger heads!) they leave me with a headache if I wear them for longer than 10 minutes. I also have many ear piercings so I don't even use these headphones because they push too tightly on the earrings and cause me pain.
