yes koss is cool, i was looking at them, but the thing is they MUST be comfy to sleep in and should be full size because those have the best bass.
edit: an easy way to tell bass is if you look at the frequency range. it will be something like 10hz-30khz. you want the first number to be as low as possible for good bass. the ones im looking at have 5hz-30khz, which is amazing, but i heard they break easily and therefore not very good to sleep in...
they are the MDR-V700DJ by sony. very nice, and less than $80 at the egg.
saw others: MDRV600 same thing but cheaper... dont knwo what the diff is so w/e i think i like these.
another development: the audio-technica ath-a55 is very nice, and you can easily get them for under 100 moneys, now all that remains to be done is to find a reliable merchant....
