jut my short opinions of how these sound. mine have had about 30 hours burn in so far. also own the ultrasone 780, RE0 and compulsory portapro's. can give detailed comparisons if requested.
i bought these last week, been using them solid since monday. so far, very pleased. i bought mine from LINDY in the uk for £77 inc next day shipping (theres a discount code TENFB to get 10% off) but they should be identical to the fischer audio FA-003 and the brainwavz HM5.
for me, they sound very similar to the sennheiser HD600, but with a bit less detail (still v.good level of detail). ive not had a huge amount of ear time with the HD600 but from what i remember they sounded very similar. to me, they both sound a little "dark", laid back and lacking in treble, but thats the sennheiser "house sound". if you like the HD600 but cant afford them or want a closed version these are a great buy.
i eq'ed them to personal taste a bit by reducing the 125-250 midbass hump slightly, adding a bit of 4khz treble and giving the 32hz sub bass a bit of a boost to reduce the roll off. the mid bass could do with being tighter but i think thats personal preference.
rock and metal sounds great on these, DnB, Hip-Hop and dubstep could be improved with a bit more speed to the bass and acoustic sounds pretty good due to the fairly small amount of resonance within the headphone cups. vocals are nice and clear too, but a touch more treble would be nice just to make them a bit more intimate and bring you a bit closer to the stage.
very comfy, with a good amount of clamp reducing the amount of pressure on your skull from the headband. nice and light weight too.
the sound stage on these is impressive, just been playing COD and you can hear people across the map, behind walls etc, but the imaging makes it a little difficult to pinpoint them on such a large stage. its just not quite as accurate as i would like, my ultrasone 780's having the more precise (but smaller) soundstage.
all in all, these are great for the money. for a quarter of the cost of the HD600 you can get a closed, easy to power portable headphone that has very similar sound characteristics, albeit a bit less detailed.
they do benefit from an amplifier, but still sound exceptional from any half decent source. 8.5/10
anyone agree/disagree?
