I've not really heard the re 262.. but its often compared to the signature of the se 535 which I've in my possession ..
and to be frank all the three are different flavours ..
1. B2 - PRaT experts - treble accentuated , the SQ is very raw and unrefined, bad dynamics of sound most neutral among the three in my opinion. Best option if you want to know how poorly the song is recorded and you have a fetish for detail
2. RE-262 - best SQ among the three,mid-forward , .. and the most ecstatic sounding among the three, since I've not heard these all I can say is that they will definitely have a very refined character than the other 2 as far as sq is concerned , mainly coz of its se 535 similarities
3. MH1c - Warm, laid back with hard hitting bass,very musical least neutral and good detail but still lag behind the above two - all about fun
If you want an all around IEM - I would definitely go for the B2, they are my favourite (i own their japanese clones) .. if its all about the feeling - get the re 262, I think it might be the best as far as SQ is concerned
