Firstly, I am no audiophile, but I can tell when a pair of headphones are decent and when they are not. This pair didn't tickle my fancy as the volume was just too low. I wanted to use it on my PS3, but the volume was so low that the in game audio was like whispering. My Laptop struggled to put out a good sound and I had to crank up the volume by a lot.Secondly, the bass is lacking. It is not totally absent and in fact seemed reasonable in most scenarios. Weirdly however, there were some particular songs where the bass was totally absent while my cheap Sony in ear buds had rich bass in those same songs. The inconsistent performance with the bass coupled with the extremely quite sound turned me off.I am returning these headphones at the earliest. I am purchasing the Superlux HD681. After a lot of research from sites like Head-fi.org I found that these don't seem to have the same issues as the Sennheiser HD201 and overall seem to have good performance, perhaps better than the Sennheiser in some respects even.It was a shame really. I was expecting great things with this Sennheiser, especially given that it is part of the Top 10 headphones for under $70, as per headphones.com.Well, they are NOT in the Top 10 list for me. Period. 

Question: How is the volume?
