Short answer: the Moondrop Blessing 3. It ranks #106 of 909 in-ear headphones by sound quality, rated 4.4/5, at $359.99; the DUNU SA6 MK2 ranks #614, rated 3.1/5, and costs $559, so there is not much of a tradeoff to weigh.
The case for the DUNU SA6 MK2: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. Watch for: Presence sits about 6.8 dB low with an 8.6 dB dip near 5.6 kHz, so vocals and instruments lose some bite.
The Moondrop Blessing 3 is the better-sounding option. Crinacle’s measurement gives it a preference score of 79, and the median of 38 hobbyist measurements on squig.link keeps every band from 20 Hz to 10 kHz within 2 dB of the Harman target, with a smooth 1.65 dB deviation. The catch: The Etymotic EVO matches its rating for noticeably less money.
Buy the Moondrop Blessing 3. It is rated higher for sound quality than the DUNU SA6 MK2 and costs less, so only choose the other one for a particular feature it does better.

DUNU SA6 MK2: $559.00 Amazon $559.00 eBay
Pros: Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. Upper treble lifts about 4.5 dB for extra air and sparkle. Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 6 x balanced armature with an easy 24 ohm load.
Cons: Presence sits about 6.8 dB low with an 8.6 dB dip near 5.6 kHz, so vocals and instruments lose some bite. A Harman score of 63 places it in the lower part of the in-ear rankings.

Moondrop Blessing 3: $359.99 Amazon $359.99 AliExpress $359.99 eBay
Pros: Crinacle’s measurement gives it a preference score of 79, and the median of 38 hobbyist measurements on squig.link keeps every band from 20 Hz to 10 kHz within 2 dB of the Harman target, with a smooth 1.65 dB deviation. The result is balanced, natural sounding vocals and instruments with full bass extension. At 14.8 ohms and 120 dB/V it is easy to drive from a phone, and it rates above the Kiwi Ears Orchestra Lite and the FiiO FH5s.
Cons: The Etymotic EVO matches its rating for noticeably less money. A 3.8 dB dip near 6.9 kHz next to a 3.6 dB peak near 8.1 kHz gives the treble slight unevenness, and sub-bass sits about 2 dB under target, so it lacks the extra rumble bass lovers may want.
