Short answer: a tie on sound quality. Both are rated 3.9/5 (#299 and #277 of 450 in-ear headphones), so choose on features and fit.
What the Kiwi Ears Orchestra does well: Eight balanced armatures per side earn a preference score of 72 in crinacle’s measurement. The tradeoff: Presence sits 5.5 dB below target with a 6.7 dB dip near 5.3 kHz, which pushes vocals and guitar bite back and makes some recordings sound distant.
Why pick the Tin HiFi T4: It earns a preference score of 73 in crinacle’s measurement, and across squig.link measurements bass and mids stay within about 1.3 dB of target from 20 Hz to 3 kHz, giving natural voices and well judged bass. The tradeoff: In squig.link measurements a 6.7 dB dip near 10 kHz and about 3 dB less presence from 3 to 6 kHz take some sparkle and edge off cymbals and guitars.
Buy the Kiwi Ears Orchestra or the Tin HiFi T4 on features: they are rated the same for sound quality at close to the same price.

Pros: Eight balanced armatures per side earn a preference score of 72 in crinacle’s measurement. Across hobbyist measurements on squig.link the bass and lower midrange sit within 1 dB of target and the largest treble peak is only 2.4 dB, so the sound stays clean and free of harshness. At 17 ohms and 111 dB it plays loud from a phone or small dongle.
Cons: Presence sits 5.5 dB below target with a 6.7 dB dip near 5.3 kHz, which pushes vocals and guitar bite back and makes some recordings sound distant. Sub-bass runs 4.4 dB under target and is 5.3 dB down at 30 Hz, so the all armature design gives less deep rumble than a dynamic driver set. It is wired only.

Tin HiFi T4: $89.00 Amazon eBay
Pros: It earns a preference score of 73 in crinacle’s measurement, and across squig.link measurements bass and mids stay within about 1.3 dB of target from 20 Hz to 3 kHz, giving natural voices and well judged bass. Sub-bass is only about 1 dB down at 30 Hz, so kick drums keep their weight. At 32 ohms and 102 dB it runs from a phone, and it rates level with the Etymotic ER2XR for less money and above the KZ PR1 at a similar price.
Cons: In squig.link measurements a 6.7 dB dip near 10 kHz and about 3 dB less presence from 3 to 6 kHz take some sparkle and edge off cymbals and guitars. Listeners who want a brighter, more vivid top end may find it slightly polite.
