Got my 8320's yesterday.....I haven't had much time to listen to them but so far I'm impressed. Not as much bass as I expected....half due to some comments written here and the size of the driver. But it is of a very decent quality and much quicker than I expected. Overall they seem fairly neutral, highs are smooth and not sibilant at all, mids are more to my liking than the SHH3580....certainly not as V shaped....rock is sounding very good with these. Soundstage is really very good, wide and far more 3D than the Philips.
What is really surprising for me is the fit.....personally they are perfect, I have not troubles at all.
I'm really interested to see what Joker makes of these, regardless of how he rates them for SQ I can only see him giving these a 10 for Value......there can't be anything out there that comes close for £8!
Thanks to Dsnuts for the recommendation and Some1 for organising the group buy!
