So I've been talking on and off with pataburd about these as I'm looking for a portable and want to get some more impressions. Here's what I've previously owned and what I thought of it. Let me know if you think these are for me
1) Sennheiser HD650 - Love the warmth and darkness. I like how airy and smokey the mids are as they make the vocals sound absolutely beautiful. The midbass is pretty spectacular although it could be a wee bit tighter at times and the treble is nice and non fatiguing although sometimes I want more extension and sparkle.
2) AKG K702 - I did not find these to be bright or strident at all like some people do. I found the mids when powered with a tube amp had nice body but on solid state I found them to be a wee bit thin. I loved the soundstage and imaging of these and thought they had an adequate amount of bass.
3) Denon D2000. Fantastic bass albeit a bit boomy. Treble was nice and well extended but I found the mids to be a bit plastic sounding which annoyed me a bit at times.
They are nothing like the HD650 (the Mikros 90's highs are not veiled and the there actually is sub-bass).
The sound of the K702 somewhat reminds me of the Mikros. The little portable has way more bass quantity, but the quality is about the same. You can forget about the soundstage being wide though.
