Pros: A hybrid of one dynamic driver, four balanced armatures and eight electrostatic drivers, it extends to 20 Hz within 6 dB of target and adds about 2.5 dB of mid-bass for a warm, full sound that suits bassy tastes. Air above 10 kHz runs about 4 dB above target, giving an open, airy top end. At 16 ohms and 104 dB/mW it runs easily from a phone dongle, and it rates higher than the more expensive 64 Audio U12t.
Cons: Hobbyist measurements give it a Harman preference score of only 65.3 despite its flagship price, largely because the 3 to 6 kHz presence band sits about 4 dB low with a 5.4 dB dip near 4 kHz that recesses vocals and instrument attack. A 7 dB peak near 8.1 kHz can make cymbals and sibilants sharp. There is no inline microphone.
