ok first impressions of the T800 - The bass is above DF target but lower than Harman target, it goes low for BA set (probably down to 35-40hz), the bass is well textured and fast but is not dry sounding, full sounding bass, it has a little bit more decay after the hit than typical BA in ear (it has vented woofers, probably that is the reason), still the bass is faster than dynamic drivers, the midrange is smooth and neutral, i am still not sure but i think it is probably one or two db up front, very slight, the mids are full and clean sounding at the same time, it is not dry, full bodied mids, it reminds me of the HD650, the treble response has extra energy in the upper treble somewhere (assuming around 11-12khz), that energy is not big but is noticeable, despite that it manages to sound smooth and organic and non fatiguing, that sparkle is adding some sort of sweetness to the treble response, the treble is clean, extended but with a musical tone, the cymbals sound full bodied and articulated, the soundstage is wide but is not the biggest from my collection, however the imaging is very specific, it has very dark background and the sounds just pop out of nowhere from the blackness with specific locations, the isolation is strong, comfort is very good for my ears(better than the HQ10)
