Query: I hate this

This is very bad. I thought it would be worth of money, but for a $50 headphone, I don't think so. It says 'powerful bass' on the cover, but i don't know how they define the word 'powerful.' I am very dissapointed and I am returning it.If you want a good bass sound quality, it is no good. but other wise, it has a pretty clear sound, but the "powerful bass" pissed me off.
