Just got the M2s about an hour ago, quickie impressions to follow:
- these sound pretty much the same as the originals. Perhaps the bass is a touch bloomier? Even then, it's just a smidgen more. Otherwise vocals are similar. The M2s handle pop and jazz with aplomb, but they couldn't quite cut it on the new Queens Of The Stone Age album. That might not be a dealbreaker just yet though, the M2s have a companion app which lets you adjust EQ.
- Sony must have done something to the physical construction of the headset because these are much more comfortable on the head. Both headsets are 275g but the M2s don't clamp as hard and the earpads are more plush. Good improvement there
-Tech-wise, the M2s have gotten a massive upgrade. If the OG 1000xs led the field with its featureset, the M2s just made yet another leap, leaving everybody else even further behind. I obviously wasn't able to test atmospheric calibration, but the Adaptive Sound Whatchamallit is the real deal. It'll now filter out voice, which worked brilliantly on a crowded bus ride.
Pics below, OG is on the left, M2 on the right. Only physical differences I can see are the textured cups and the Sony branding on the side
