I *REALLY* wish you guys made the MS400 a detachable, single-sided model. THat would probalby make it perfect.
The MS300 is good, but not great. I love the form factor, design and portability though. Sound is a little bright for my tastes, but it's nice to have a different sound sig every now and then compared to all my heavy bass cans lying around.
I will be picking up an MS400 soon and hope the sound is really good. My only regret is the damnable two-sided cable! Wish it were single-sided and detachable!!!
