Tested on: - Cowon D2 mp3 player - PC with Sound Blaster X-FI

- requeres burn in (very nasty sound for the first hours of play) + Excelent Isolation -> very nice sound at very low volume (risc of damaging the ear are lower) + Sound clarity/precision Excelent, ideal for clasic music entuziasts + travel box with silicon cristals absorbs humidity from the earphones + no distorsion at very high volume (i don't recomend using them at high volume)

I bought the phones one year ago and i used them allmost on a daily basis. I recomend them to audiophiles.

MY TEST SETUP: MP3-player: Sandisk Sansa Fuze Music: FLAC Amp: Portable FiiO E5

- easy to drive with an MP3 player (you don’t have to turn the volume high) - extreamly wide soundstage - not ideal for bicycle because the you hear the wind-noise. The main reason for this is the big plateshape of the speaker’s back - but the advantage of this shape-form is that you can lie on your side (sleep-rest-chill effect in bed is superb) - in the first 3 weeks (at average use) the bass is too much, even if you turn the trigger at minimum, but don't be afraid because the burn-in will help a lot - burn-in time (100-200hours) is annoying but it makes wonder (basically i don’t care about this) - strange to put the half-ring on your ear (it takes a lots of time but after practise you can handle this faster) - lot's of detail - Flac is significantly better than MP3 (320kbit/s) - expensive but very-very good value - extreamly high clarity -> not so warm sound signature as iGrado (not so much texture) - high notes are amazing (i hear even the highest notes supernatural and relaxed-sounding) - bass is rounded and detailed - very comfortable

i would say for the sound signature: direct sounding bass monster with highfreq-clarity out of this world and huge soundstage

My Ety ER-4S has no chance...
