Thanks for the replies.
Yeah the avantone mixcubes.
I just found them easy to mix on, the trouble for me is I am always traveling around and frequently writing/editing/mixing on my laptop. My Dt880pros feel like mixing on full range monitors and I find the bottom end and top end distracting in the same way I find it distracting on big monitors.
i.e. Mixing is easier with two different sets of speakers.
So I was thinking about the same thing with headphones i.e. I like the dt880s which are open back headphones, but don't find them particularly helpful for predicting my mixes behaviour on smaller speakers or crap car stereos which often mock me
So I have been wondering if there is a way of monitoring on headphones that will predict my mixes behaviour in a way thats comparable to using mixcubes/auratones.
I suppose I can always highpass and lowpass filter my mixbuss until focusrite or someone else brings out a Audio Unit version of VRM but as with all things audio its rarely that simple :(
Glad Behringer are gonna hit the market with some cheap auratone copies will be really interested to see how they perform as the mixcubes are pretty serious cash

at least they could fit in a small bag.
