When compared to most low-cost headphone offerings, it's great to be able to get something like this from a reputable manufacturer which you know stems from a design made for studio use.
As a cousin of the M50 X variant, these are the cheapest in the range and after reading a few reviews I felt confident enough to buy 2 pairs for when I have musicians tracking in my home studio.
I intend to buy more in the future as its very nice to have all headphones with the same EQ fingerprint so that headphone preamp levels can be set the same and I can EQ the mixes all the same way, knowing that a 5db increase for one person will be the same for all.
An added bonus is that's I can carry these headphones around shoved in my laptop bag for a less critical listening - they're very enjoyable to listen to music on generally and despite a little bit too much warmth are smooth enough to be used for everything except surgical EQ.
They sound a little towards the home hifi end of tone, a little warmer and slightly loudness-character to them, but really smooth and pleasant all the same.
Compared to other studio closed cans for tracking, I really don't know why everybody isn't using these!
So good for the money - but they are nonetheless a plastic headphone and I suspect would survive being trodden on, but who cares, they are cheap to replace.
