KZ DQ6 rank A-.
It’s been a few years since I got a KZ and WOW, it is a great iem.
Tight, fast and well textured bass that’s fun because of the elevation but is clean because of the tightness and speed.
Mids are recessed giving it a V-shaped sound, but is very natural because of the timbre and tonality (although the tonality is leaning a bit more towards brightness, so some male vocals do need more warmth).
Treble, while it is very airy and the quantity isn’t too much for me, it is a bit unrefined and peaky. Which is the biggest weakness along with the technicalities (except soundstage) where it is actually good for this price, but doesn’t punch much higher (same level as the blon bl-03 (mesh mod)). Soundstage is very big though, probably the biggest soundstage you can get at this price and it definitely can rival stuff in the 100-200 usd range. Timbre is also very good along with coherency.
It is like a mini Fiio FD5 but a bit more recessed mids and more unrefined/peaky treble and technicalities arent in the same league. If you like the DQ6, the upgrade to it would be the FD5.
