Bass is not everything
: Bass (quantity), short cord (subjective), 18-wheeler looks (subjective)
: Bass (quality), mids, clamping force, non-folding, non-detachable cord
They're good for bass and nothing else. They're not even comfortable, the clamping force resembles the M-Audio Q40's in my opinion (which would make them good for cycling, running and walking but not so good for stationary usage). The quality of bass is also not the best and you still need to give it a +6db or a higher boost for the subwoofer-on-your-head effect (which actually distorts the bass, +4db seems to be the upper limit). The mids are awful, making tracks like Simon Patterson - Always or Jon O'Bir feat. Fisher - Found A Way (Joint Operations Centre Remix) unlistenable - but that depends on the track. The highs are OK after equalization (a +4db boost, give or take).
Unless you can get them for free or almost for free, stay away from them. That's considering their current price, I got mine for 100 euro. The truth is that they're worth 5 to 10 euro at best. Buy some older Ultrasones instead (preferably the HFI-580's, or the DJ1's which are the same cans). They provide a bigger (you read that correctly) amount of much clearer bass (without the need of EQ) and they have much better mids, not to mention a longer cable if you need it.
EDIT: I'm lowering my rating after listening to them for ~10-15 more hours. They're really bad, possibly the worst headphones I've ever had. Aerofoil - Caress 2 Impress (Markus Schulz Big Room Reconstruction), Mike Shiver & Aruna - Everywhere You Are and probably a dozen more tracks join the list of unlistenable tracks on these.
also here's the worst part... years ago when those where in production the XB 700 could be had for about $80 new and sounded better imo than the UE 6000, now fast forward to today and the XB 700 might run you $200 if you can find one and the UE 6000 is really just a better b ang for the buck! Sony biggest mistake was discountinuing these to make their new even numbered line :/
