After roughly 100 hours of burn-in, I sat down to listen to these. A lot has changed in my equipment stable since I had the rev. 1 of these. In the interim I've auditioned Audeze LCD-2, upgraded the amp for my Koss ESP-950, and ultimately settled on the Fostex TH-X00 Mahogany as my daily cans.
In comparison with the X00, these are... well... "meh". Kinda dull actually. I don't get the lively immediacy of the music I get with the Fostex. That doesn't mean that the M1060 are *technically* worse; in fact I would posit that they are probably more accurate/flat, but there's just something the Fostex X00 do with the music that I just like better.
The manufacturing quality of the M1060 rev. 2 is definitely better than rev. 1, but I still question how well they will hold up over time. The 1/8 to 1/4 adapter is, as other have mentioned, complete and utter garbage. I had the same problem as others with the sound cutting to mono; at first I thought I had a bum set of headphones, but switching to an adapter I had here in the office solved the problem.
Hopefully a $1.49 adapter doesn't end up putting people off these headphones because what they hear sounds like a$$. Big mistake by Monoprice, as this cheap weakest link could cost them sales.
Ultimately for me though, these aren't the ticket.
