Summary: These has a nice warm sound with good, but not bloated bass. On a city bus they do a good job at cutting out the background noise, however some of the bass is lost in the rumble of engine. I use them every day on my hour long comute listening to everything from Celtic to Metal to Jazz and they all sound good to my ears. In a quiet place they have surprised me with their deep bass and warm mids. I really like listening to these and have put away my Klipsch S4's for good.
Summary: What first attracted me to these headphones was a review I read on a tech blog. Upon reading the companies recycling philosophy (send in your old headphones and they give you 15 dollars off, if you send in an old pair of Thinksounds you get 25$ dollars off) I knew where I was getting my next pair of headphones from. After buying a pair I have to say I am pleased as the proverbial punch with my purchase.
