Short answer: the Tin HiFi T4 Plus. It ranks #70 of 450 in-ear headphones by sound quality, rated 4.5/5, at $69; the QKZ Khan ranks #139, rated 4.3/5, at $69. The price gap is small enough that the sound-quality ranking should decide it.
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. Watch for: 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 Tin HiFi T4 Plus. It is rated higher for sound quality than the QKZ Khan at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

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.
