Pros: Measured response gives it a solid Harman preference score of 72 with a 3.06 dB spread, and its mids sit within about 0.7 dB of target, so vocals and instruments sound natural.
Cons: Presence sits about 3.9 dB low with a 12.2 dB dip near 9.6 kHz, so vocals and instruments lose some bite. Sub-bass is 7.6 dB short at 30 Hz, so deep bass lacks rumble.
