Short answer: the KLH Ultimate One, though neither ranks well in its class. It ranks #415 of 481 over-ear headphones by sound quality, rated 2.5/5, at $325.11. The SteelSeries Arctis Nova Pro Wireless ranks #438, rated 2.2/5, at $299.99, $25.12 cheaper, which does not close the gap in sound quality. 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.
Why pick the KLH Ultimate One: Bass from 60 to 200 Hz runs about 8.5 dB above target with sub-bass 5 dB up, so bass lovers get heavy, rumbling lows from an open headphone. The catch: In oratory1990’s measurement the treble also sits about 5 dB above target from 3 to 16 kHz with a 9.6 dB peak near 6 kHz, which can make vocals and cymbals sound sharp and tiring at volume.
The case for the SteelSeries Arctis Nova Pro Wireless: A gaming headset with active noise cancelling, a built in microphone, and both wireless and wired connections, so one headset covers PC, console and mobile use. Watch for: A 13.0 dB dip near 4 kHz leaves presence 6.8 dB below target, so dialogue and vocals sound veiled and distant, contributing to a low preference score of 41.5 with an uneven 3.82 dB deviation.
Buy the KLH Ultimate One. It is rated higher for sound quality, and saving $25.12 with the SteelSeries Arctis Nova Pro Wireless does not make up for the sound-quality gap.
