I was very happy with my two sets of 'phones', big, meaty, traditional Sennheiser HD 580's for through the amp listening, and Shure EC2's for out and about listening (iPod, Minidisk and personal CD player). I no longer have my amp, having moved over to active speakers, and my portables are a little feeble in output to drive the 580's. I would like a pair of fairly small, fairly portable, efficient (easy to drive) headphones, not in-ear. The Shures are good sounding, but I find them quite uncomfortable to wear for very long, even with the (and let's be honest, disgusting looking) foamy earplugs. Any feedback would be gratefully received. I'd be happy to spend £50, give or take.
