Any idea on Audeze MM-100?

[Slash7]

I was considering purchasing the Beyerdynamic DT 900 Pro X due to its excellent bass response. However, I then learned about the planar magnetic Audeze MM-100s. Although they're more expensive than the Beyers, I'm OK to pay more for an Audeze.

My main concern is the bass and sub-bass response of the MM-100s. As my 5-inch monitors struggle to reproduce these frequencies, I need to rely on my headphones. Could anyone provide insights into the overall sound quality of the MM-100s? I primarily mix indie, pop, and rock music.

As a side note, I also own a pair of DT 770 Pro headphones and I don't have access to any Audeze stores to test their headphones.

I have a set of the MM100s (and also use DT770s and DT990s). Somewhat weirdly I don't tend to use them in the studio, but they are my final mic check (replacing an old set of Philips cans that finally bit the dust).
I actually prefer my 990s for double-checking low end and I have a set of AKG702s that are more revealing around the mid-range. What I find though is that if something sounds good overall on the MM100s it will probably translate well across most playback systems. I like the fact that they're not over-hyped at the top end.

Other good points are the comfort (both ear cups and head strap) and the lack of noise transmission to the outside (despite being open back I can wear these in bed without aggravating my other half!)

On the downside, the headstrap doesn't stay attached to the little pegs very well and is constantly falling off. I need to get a couple of rubber washers to fix it in place but haven't got round to it (which tells you it's not a big problem). They are also quite heavy, but because of the high comfort factor that's never been a problem.
