Query: Very happy with them...

I use these headphones to listen to my iPod. I don't know about bass or any of that, but I know what sounds good and these sound good. The only drawback is that the cord is very, VERY long. There's something for you to wind it up on, but it can still be a pain if you're just using it for your iPod since the wound up cord will be bigger than the music player itself.But, overall, very happy!
