Alrighty..... so I already own a pair of M50's, and as you may already know they are obnoxiously large and, well just obnoxious. I started looking for a pair of more portable headphones to replace my m50's on the go, and I was looking for a fun bassy sounding headphone. Well I got exactly that. The bass could be a little better at the extremely low bass, and it doesn't sound that airy. Also, it feels just right in your hands, it might feel fragile at times but it is actually very well built. Another thing, is that they aren't quite circumaural, they're more like supraural at one half and circumaural on the other. Still, it is insanely comfortable thanks to the faux pads, that are just so SQUISHY, I love it.
