Short answer: the Sony INZONE H6 Air. It ranks #211 of 481 over-ear headphones by sound quality, rated 3.7/5, at $198. The Sennheiser HD 599 ranks #215, rated 3.6/5, at $189.95, $8.05 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Sony INZONE H6 Air does well: A light 0.4 lbs (199 g) open back gaming headset with a built-in microphone that runs easily from a controller or PC at 28 ohms and 99 dB/mW. Watch for: Bass and low mids run 2.6 to 4.3 dB heavy, thickening voices, while a 7.6 dB peak near 8.4 kHz next to a 6 dB dip near 9.7 kHz gives cymbals an uneven, edgy texture.
The case for the Sennheiser HD 599: A preference score of 73 and a modest 2.74 dB deviation from the Harman target in oratory1990’s measurement make this a fairly smooth open back. The catch: Sub-bass falls about 6 dB under target below 60 Hz, so the extra warmth sits higher up and the deepest rumble is missing.
Buy the Sony INZONE H6 Air. It is rated higher for sound quality, and the $8.05 saving on the Sennheiser HD 599 is not enough to make up the difference.
