I'll just go ahead and suggest the Senheiser CX300 II's. I bought them a few weeks ago to replace my aging EX85's oddly enough.
They are awesome headphones at any volume, brilliant quality and incredibly comfortable. They are better than the Sonys at high volume and the bass is a bit more powerful which is perfect for me and my obsession with Techno and EBM, also they are more comfortable and are MUCH less noticeable, the Sony's are annoying in that they stick out quite a bit.
The Sony's are durable, but the ear plugs come off a bit too easily for my liking (came off in my ears a few times when I took them out), the Senny's however a bit more secure, they also have a more durable cord.
Now I just need to wait for my Penquin Amp to arive and my life will be complete.
