Short answer: the Simgot SuperMix 4. It ranks #29 of 1291 in-ear headphones by sound quality, rated 4.8/5, at $169.99. The Moondrop Voyager ranks #56, rated 4.7/5, at $149.99, $20 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Simgot SuperMix 4: Across 48 hobbyist measurements on squig.link it scores 83 for preference, with an average deviation of only about 1 dB, so the overall balance is even and easy to like. The tradeoff: A roughly 3 dB dip near 6.5 kHz and a presence region about 2 dB under target make vocals and guitar attack a touch recessed, while a 5.7 dB peak near 11.9 kHz adds a hint of glare up top.
What the Moondrop Voyager does well: These wireless earbuds track the Harman target unusually closely, with a preference score of 82.1 and only 1.2 dB of deviation in hobbyist measurements, and bass through the upper mids stays within half a decibel of target. Watch for: The 3 to 10 kHz range sits about 2.5 to 2.7 dB below target with a 4.8 dB dip near 9.7 kHz, which softens cymbals and detail slightly.
Buy the Simgot SuperMix 4. It is rated higher for sound quality, and the $20 saving on the Moondrop Voyager is not enough to make up the difference.
