The babies have arrived!
Not gonna comment on the sound yet.
As far as comfort goes though, other than the velours being slightly itchy [it seems to be going away with time though] it is supreme.
First impressions are positive - it is bassy but not as bassy as I'd thought [good!], sound is a bit soft with the stock cable [expected, but it's subtle, compared with a cable I had lying around, still waiting for the one I've ordered though], a bit less airy than the MA900 [IMO] but very relaxing sound yet still involving [IMO].
So far very good with music, will test with games later tonight,
I gotta say, the MA900 and X1 are rather different, still both very, VERY good.
Keeping both!
[Itchiness is gone :]]
Also, beautiful headphones, they are!
