Hmm, I think a lot of the misconceptions on the miles davis is due to the fit.
My initial impressions mirrored a lot of yours, but I don't think the hate is deserved.
The mdt are amazing with tips that isolate well/seal up the canal/small sound bore preferably. Having tried them with my ms2+/o2 combo, I find them incredibly open and dynamic. Mids are their strong point, and highs are sparkly enough. If anything I think the meaty tight bass has excellent speed.
One thing I've noticed is the mdt has horrible synergy with most low/mid-fi DAPs, probably the reason why initially not so enthused.
I like these babies, but a little fatiguing signature for long term listening.
And for the last time, most foam tips including comply have a negative effect. They have a tendency to darken the signature, decreasing transparency and details, muffling things essentially.
i would agree, if I hadn't used the silicone tips and had almost the same effect.
