Short answer: a tie on sound quality. Both are rated 4.3/5 (#156 and #145 of 450 in-ear headphones) at nearly the same price ($59 vs $59), so choose on features and fit.
What the Tin HiFi T3 Plus does well: Crinacle’s measurement gives a preference score of 77 with only 1.78 dB of deviation around the target, an unusually smooth response for an inexpensive in-ear. The tradeoff: Presence and treble sit about 2 dB under target with a 5.7 dB dip near 6.3 kHz in the squig.link measurements, which softens cymbals and sibilance for a slightly relaxed sound.
Buy the EPZ K5 or the Tin HiFi T3 Plus on features: they are rated the same for sound quality at close to the same price.

Tin HiFi T3 Plus: $59.00 Amazon eBay
Pros: Crinacle’s measurement gives a preference score of 77 with only 1.78 dB of deviation around the target, an unusually smooth response for an inexpensive in-ear. Across 16 hobbyist measurements on squig.link sub-bass holds within 0.5 dB down to 20 Hz and a gentle 1.6 dB bass lift adds warmth without boom. A single 10mm dynamic driver at 32 ohms runs easily from a phone, and it rates higher than the pricier Tin HiFi T4.
Cons: Presence and treble sit about 2 dB under target with a 5.7 dB dip near 6.3 kHz in the squig.link measurements, which softens cymbals and sibilance for a slightly relaxed sound. It is wired only and has no built-in microphone for calls.
