Short answer: the HIFIMAN Sundara. Both are rated 4.0/5 for sound quality (#61 and #70 of 216 over-ear headphones), and the HIFIMAN Sundara costs $179 against $199 for the HIFIMAN Deva Pro, with sound quality a draw, the lower price decides it.
Why pick the HIFIMAN Deva Pro: A preference score of 81 with a deviation of 2.2 dB in oratory1990’s measurement shows a smooth, slightly warm response with the midrange close to target. The catch: Sub-bass is about 7.5 dB under target, so deep bass lacks rumble.
The case for the HIFIMAN Sundara: Crinacle’s measurement gives a preference score of 82, and the midrange and treble stay within about 1 dB of target in hobbyist measurements on squig.link, so voices and instruments sound natural with a neutral balance. The catch: Sub-bass falls about 5 dB below target under 60 Hz and is 6.1 dB down at 30 Hz, so kick drums and synth bass lack deep rumble.
Buy the HIFIMAN Sundara. Both are rated the same for sound quality, and it costs $20 less than the HIFIMAN Deva Pro.

The Two Headphones In Full
HIFIMAN Deva Pro: $199.00 Wireless Amazon eBay
Pros: A preference score of 81 with a deviation of 2.2 dB in oratory1990’s measurement shows a smooth, slightly warm response with the midrange close to target. The planar magnetic driver is easy to drive at 18 ohms and 93.5 dB, and it can connect wirelessly or by cable. The open back gives a roomy sound.
Cons: Sub-bass is about 7.5 dB under target, so deep bass lacks rumble. Treble from 6 to 10 kHz is about 4.1 dB low with a 9.4 dB dip near 9.2 kHz, which dulls cymbals and detail. At 360 g it is heavy, and the open back leaks sound with no isolation.

HIFIMAN Sundara: $179.00 Amazon eBay
Pros: Crinacle’s measurement gives a preference score of 82, and the midrange and treble stay within about 1 dB of target in hobbyist measurements on squig.link, so voices and instruments sound natural with a neutral balance. The air band is lifted almost 4 dB above 10 kHz, adding openness and detail without a harsh peak. The open-back planar design gives a spacious presentation, and it is rated equal to the AKG K612 while costing less.
Cons: Sub-bass falls about 5 dB below target under 60 Hz and is 6.1 dB down at 30 Hz, so kick drums and synth bass lack deep rumble. At 94 dB/mW it needs more power than most over-ears and can run short of volume from a phone, and 372 g is heavy. The open back leaks sound and offers no isolation.
