Short answer: the Beyerdynamic DT 770 M, though neither ranks well in its class. It ranks #442 of 481 over-ear headphones by sound quality, rated 2.0/5, at $199.99; the Sony INZONE H9 ranks #456, rated 1.6/5, at $198. Close enough in price that the sound-quality gap is the deciding factor. Both are rated below 3.0/5 among the 481 over-ear headphones; for better sound, the Sennheiser HD 550 ranks #8 at $199.95.
The Beyerdynamic DT 770 M is the better-sounding pick. A closed back design that blocks outside noise better than an open back, with an 80 ohm load and 105 dB sensitivity that a phone or laptop can drive. The tradeoff: A deep 15.6 dB dip near 3.6 kHz and a presence band about 7 dB low push vocals and guitars back and make the sound muffled.
What the Sony INZONE H9 does well: Active noise cancelling and 32 hours of battery (ANC off) suit long gaming sessions, and it has a built-in microphone. The catch: A 13.8 dB hole near 4.6 kHz and a 13.2 dB spike near 11.9 kHz make the response very uneven, with a preference score of 29, so voices recede while treble hiss and sibilance stick out.
Buy the Beyerdynamic DT 770 M. It is rated higher for sound quality, and saving $1.99 with the Sony INZONE H9 does not make up for the sound-quality gap.
