These are, in my opinion, good quality headphones for a great price.
That being said, I must point out that if you're listening to music at deafening levels with lots of bass you will likely be disappointed. Now, this may be partly due to my laptop output, but when you crank up the bass boost and crank up the volume the bass obviously struggles. This is acceptable for me because I don't need to be listening to music that loud anyway.
These are very comfortable, with a padded headband and the earcups are big enough to be comfortable. They also have a pretty long cord, which is great for me!
