Short answer: the JVC HA-FW1500. Both are rated 3.4/5 for sound quality (#359 and #366 of 450 in-ear headphones), and the JVC HA-FW1500 costs $766.28 against $899.99 for the DUNU Zen Pro, and with sound quality even, the cheaper one is the better buy.
What the DUNU Zen Pro does well: A single dynamic driver with bass, low mids and upper mids all within half a dB of target in squig.link’s hobbyist measurements, so voices and instruments keep a natural, even body. The catch: An 8.3 dB dip near 6.4 kHz and a 4 dB shortfall across 3 to 10 kHz dull cymbals and blunt the edge of vocals, while a 4.6 dB peak near 11.5 kHz adds a little uneven sparkle.
The case for the JVC HA-FW1500: The 11 mm dynamic driver rates a manufacturer specified 6 Hz to 52 kHz, and Crinacle’s measurement shows a Harman preference score of 66 with a mild warm tilt of 0.53 dB. The tradeoff: A score of 66 is middling and a deviation of 2.69 dB means audible coloration, which is hard to justify at a flagship price.
Buy the JVC HA-FW1500. Both are rated the same for sound quality, and it costs $133.71 less than the DUNU Zen Pro.

The Two Headphones In Full
DUNU Zen Pro: $899.99 HiFiGo eBay
Pros: A single dynamic driver with bass, low mids and upper mids all within half a dB of target in squig.link’s hobbyist measurements, so voices and instruments keep a natural, even body. It matches the rating of the Unique Melody MEST Mk2 at a much lower price. At 16 ohms and 112 dB sensitivity it is easy to drive from a phone.
Cons: An 8.3 dB dip near 6.4 kHz and a 4 dB shortfall across 3 to 10 kHz dull cymbals and blunt the edge of vocals, while a 4.6 dB peak near 11.5 kHz adds a little uneven sparkle. Sub-bass sits about 3.5 dB below target, so the deepest rumble is lighter than the midbass suggests, and its 3.1 dB deviation makes it one of the less even tunings at this level.

JVC HA-FW1500: $766.28 Amazon eBay
Pros: The 11 mm dynamic driver rates a manufacturer specified 6 Hz to 52 kHz, and Crinacle’s measurement shows a Harman preference score of 66 with a mild warm tilt of 0.53 dB. The 16 ohm impedance and 103 dB/mW sensitivity make it easy for a phone to drive. It has been out since late 2019.
Cons: A score of 66 is middling and a deviation of 2.69 dB means audible coloration, which is hard to justify at a flagship price. The HIFIMAN RE2000 and FiiO FD5 are both rated higher, and the FiiO costs far less. It is wired only and lists no microphone.
