I love how this headphone sounded right off the box. The bass is OK for what they cost. It isn't to cheap and isn't the best of course. just enough. They don't really cancel sound unless you put the volume all the way up. The sound quality is actually pretty crisp and there isn't a echo that you would find in super cheap headphones. This is the best way you can go for 30 dollars. The mic is good, I like how it has the switch to turn it on and off. And the volume adjuster to lower the volume without moving anything on the tv or pc is a nice feature as well.
