Short answer: the Sony INZONE H9 II, though neither ranks well in its class. It ranks #440 of 481 over-ear headphones by sound quality, rated 2.1/5, at $348; the iBasso SR1 ranks #465, rated 1.5/5, and costs $399, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 481 over-ear headphones, so if sound quality matters, consider the HIFIMAN Ananda Nano instead, ranked #6 at $319.
The Sony INZONE H9 II is the better-sounding option. Active noise cancelling, 30 hours of battery (ANC off), a built-in microphone, LC3 support and a wired option make it a flexible gaming headset at 0.6 lbs (260 g). The catch: A 9.2 dB peak near 7.2 kHz and treble about 5 dB over target make cymbals and sibilance edgy, while a dip near 3.9 kHz pushes voices back, for a preference score of 38.
Why pick the iBasso SR1: A low 22 ohm impedance means the 50 mm dynamic driver runs from a phone or laptop without a separate amp. Watch for: Crinacle’s measurement gives it a preference score of only 25, with a steep warm tilt and large deviations of about 4.5 dB on average from the Harman target, so most listeners will hear a muffled, uneven balance.
Buy the Sony INZONE H9 II. It is rated higher for sound quality than the iBasso SR1 and costs less, which makes it the one to get unless you need something the other one does better.
