Pros: Crinacle’s measurement gives it a preference score of 75, and the median of 13 squig.link measurements keeps sub-bass, bass, low mids and upper mids within 0.7 dB of target, so vocals and instruments sound clean and correctly weighted. The hybrid pairing of a 10mm dynamic driver with a balanced armature holds deep bass to 20 Hz, and 108 dB sensitivity at 32 ohms makes it easy to drive from a phone.
Cons: Presence runs about 2.9 dB and air about 3.4 dB below target, with a 6.8 dB dip near 11.9 kHz, so cymbals lack some sparkle and the top end feels slightly reserved. A 4.4 dB peak near 10.3 kHz just below that dip makes the upper treble a little uneven.
