hi, did you manage to see how the sound of the M2 compares directly with the Sennheiser HD 600? I own the M2 and I'm very curious of the comparison thanks

I have to rely on my memory here but I did think the M2 was much less versatile compared to the HD600. It colors the sound and has a narrower sound stage. HD600 really are some killer headphones which I recommend highly. Since then I also got a pair of B&W P7 which I think makes a good contrast to the HD600.

got it,thank you very much for the reply
