...these comparisons to the HD600 are killing me.
Could anyone compare passive vs. active (non-NC) unamped? (preferably directly out of a Macbook Pro) I was really trying to hold out for the M4U 1 before taking the plunge as I have zero interest in active noise canceling, but I'm finding more and more that I'm plugging in 'phones for a "quick listen" that turns into a casual multi-hour rally. If the active is truly a benefit and doesn't cause any nasty distortion to the frequency response, then it may be worth the additional investment for the M4U 2.
Also, are there any white sheets claiming that the M4U 1 is, in fact, the same exact headphone as the 2 version sans the extra electronics? Any more hints on a release date? I contacted PSB last week and their response was that they don't have any information about upcoming product releases.
Of all the noise cancelling headphones out there, these sound the best by a mile in passive mode (many don't even work in passive mode). In fact, with a headphone amp, I would say they sound better in passive mode compared to the onboard amp. I agree with all the positive reviews. The M4U2 is at the top of my list based on headphones I have heard. I am waiting for the V-Moda M-100 and Denon AH-D600 before making a final decision. The Polk 8000 sounds interesting, particularly with the strong bass. However, Tyll said they sound as good as his AKG K550 which might be a good thing, except Tyll and I are rarely on the same page with headphone sound and I don't like the AKG K550. Plus, and this is the dealbreaker, the Polk 8000 doesn't work unamped. So I can imagine going for a nice walk, the rechargeable battery dies half way through, and I am stuck in silence the rest of the way.
