Short answer: the Austrian Audio Hi-X55, though neither ranks well in its class. It ranks #368 of 481 over-ear headphones by sound quality, rated 2.9/5, at $340.28; the JBL Tour One M3 ranks #377, rated 2.8/5, and costs $347.99, which makes this an easy call rather than a real tradeoff. 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.
What the Austrian Audio Hi-X55 does well: The closed back blocks outside noise and keeps sound from leaking, so it works in shared rooms and studios. Watch for: oratory1990’s measurement shows a deep 9.9 dB dip near 2.3 kHz and presence about 3.9 dB below target, so vocals and guitars sound recessed and distant.
What the JBL Tour One M3 does well: Active noise cancelling is paired with a long claimed battery life of 40 hours with ANC on and 70 hours with it off. The tradeoff: In two hobbyist measurements on squig.link it scores 55.7 for Harman preference, held back by a 4.9 dB presence dip in the 3 to 6 kHz range and a 10 dB dip near 9.2 kHz.
Buy the Austrian Audio Hi-X55. It is rated higher for sound quality than the JBL Tour One M3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
