Grabbed a pair of m1060s...I really like these. I don't notice any of the complaints that people have mentioned, and it sort of hits the "all around" mark that my SHP9500s also does. It's got a nice representation across all frequencies to me, but still has a very fun "groove" to it due to bass quality and the overall warmer tilt. It's definitely not as gritty or bright sounding as the SHP9500s and has a very smooth character to it. I don't want to say that these are "relaxed", but they're not as up front and edgy as I was thinking they could be; these are just very easy to listen to. The most noticeable thing to me is that it just sort of feels like the bass/mids/treble all sort of happily coexist, and that everything in the song sort of sits in the mix on its own without being overwhelmed/blurred/overshadowed by anything else. These are winners.
Build quality though is just funny...flippy, floppy, sort of creeky feeling stuff...but the pads are great and it does sit very steadily on my head without any problems. A headband upgrade would probably make these really great to wear. I can also see immediately where people would get the idea to try a more breathable pad on these...SHP9500s do sound more open and airy, and I think it's due to the porous cloth pads vs the glued/sealed leather pads. I'm interested in seeing how these sound without the foam inserts and can see why people try to put those vegan pads on these. I like them a lot as they are, but I bet they would sound amazing if opened up a bit.
I have a pair of the m560s coming on Monday, but I'm pretty sure I'll be sending them back and keeping the m1060s. Still going to test them out though, but the m1060 is such a good thing and I can't see how I could let them go now.
