Short answer: the TANGZU XuanNv. It ranks #59 of 450 in-ear headphones by sound quality, rated 4.6/5, at $79. The Tin HiFi T4 Plus ranks #70, rated 4.5/5, at $69, $10 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the TANGZU XuanNv: Its dual dynamic drivers score 80.4 in squig.link hobbyist measurements, with a smooth 1.32 dB deviation and a slightly warm tilt. The catch: Presence sits about 3.1 dB below target with a 5.2 dB dip near 6.2 kHz, so vocal articulation and snare crack lose some bite.
Why pick the Tin HiFi T4 Plus: Across ten squig.link measurements it scores 80.0 for preference, with sub-bass sitting right on target down to 30 Hz and a 2.2 dB bass lift that gives drums and electric bass a satisfying thump. The tradeoff: Treble climbs to a 4.8 dB peak near 11.9 kHz, which some listeners hear as hiss or shimmer that sits above the music.
Buy the TANGZU XuanNv. It is rated higher for sound quality, and the $10 saving on the Tin HiFi T4 Plus is not enough to make up the difference.

TANGZU XuanNv: $79.00 Amazon eBay
Pros: Its dual dynamic drivers score 80.4 in squig.link hobbyist measurements, with a smooth 1.32 dB deviation and a slightly warm tilt. Bass and low mids stay within half a decibel of target and sub-bass extends cleanly to 20 Hz, so it suits warm and bassy listeners who want fullness without boom. Treble peaks are mild, topping out at 1.5 dB near 8.2 kHz, which keeps cymbals and sibilance relaxed for long sessions.
Cons: Presence sits about 3.1 dB below target with a 5.2 dB dip near 6.2 kHz, so vocal articulation and snare crack lose some bite. The 98 dB sensitivity is a little lower than most in-ears, so expect to turn a phone up further than usual.

Tin HiFi T4 Plus: $69.00 Amazon eBay
Pros: Across ten squig.link measurements it scores 80.0 for preference, with sub-bass sitting right on target down to 30 Hz and a 2.2 dB bass lift that gives drums and electric bass a satisfying thump. The midrange stays within about 1 dB of target, and a 3.9 dB air lift keeps it from sounding closed in. At 4 g per earbud and 106 dB sensitivity it is light and easy to drive.
Cons: Treble climbs to a 4.8 dB peak near 11.9 kHz, which some listeners hear as hiss or shimmer that sits above the music. A 3.3 dB dip near 5.9 kHz slightly blunts snare and vocal consonants.
