We probably have a different definition of musical, George
RE800 sound is on a thinner side, lacking body and naturalness in tonality, bass is neutral, upper mids are lifted, bright, closer to analytical level, treble is edging toward sibilant. Definitely plenty of airiness and transparency, but that 7k peak hits my eardrums hard
I definitely think it will find fans if you are not as sensitive to bright upper mids/treble or use a warmer source, but if you are a fan of a natural musical tonality, these will sound harsh.
The shell indeed, very comfortable, reminds me a lot of their classic RE400, very lightweight. But as I mentioned in another thread, I just wish they would have a strain relief where cable connects to the shell.
That's how I captured FR of RE800 with Veritas (obviously, not a professional setup, but that's exactly how i hear it in this uncompensated measurement).
