Still want to try the Beyerdynamics tho! for gaming. Depends on interference, and there is a bit of wireless noise.but not too shabby for a hundred bucks. Strange as it may seem (have k612's and k271 mkii's, and had my babies the k171 old-skools, which need yet another soldering job! diagram someone?), my wireless POS k912 aren't sounding half bad for what they are.can wander pretty far (up two stories, out on the balcony etc) and the sound isn't terrible. I still have my O2 and it sounds fine with all my other hp's so this is not an issue for me and after hearing other members pairing them together successfully it must have been a synergy issue. It may have been the DAC in the NAD player that didn't play nice with the HD600 but either way when I switched back to the other setups the sound was again glorious! After reading those comments I setup the O2 with my NAD c542 (don't believe I used an external DAC) and the sound was grainy and lacking with the HD600, I never heard them sound that poorly. On both these systems the HD600 sounds absolutely fantastic. I usually pair my HD600 with my Keces HA-171 amp and Maverick Audio D2 DAC but also listen to them on another setup I have for my DT880's which is a LD MK III amp and Beresford Bushmaster MK II DAC setup. Unfortunately he was somewhat correct but I do not think it sounded as bad as he was describing. Another member made some over the top negative comments on the O2/HD600 pairing and having both but never pairing them together I had to try thinking he must be completely wrong.

Compared to Q701 however, K612 sounds fuller with more appropriate warmth and pretty much none of the unnatural upper midrange glare/boost that the Q701 has to my ears.įirst let me say I love my HD600's and enjoy the O2. Can't say K612 lacks body in absolute terms, just in comparison with HD600. The AKGs may need a good tube amp to give their sound a bit more body and richness. I think it can surpass HD600 in some aspects, such as instrument separation and bass depth.

Perhaps K612 will work better with a different amp. K612 is absolutely fantastic for the price and comes very close to HD600 in sound quality, but is not quite there, at least not out of the O2 + Fiio X5/Essence STX. HD600 just sounds a bit more natural with more depth to the sound, fuller body, a bit more transparency. Which DAC are you using to feed the O2? I am mostly using Fiio X5 or Essence STX, both of which use PCM1792A DAC.īTW, I do prefer HD600 with O2 over K612 with O2.

What was it exactly that you didn't like about it? It could also be a synergy issue with your DAC. I think my HD600 sounds great with my O2.
