Short answer: the Nothing Ear. Both are rated 3.8/5 for sound quality (#569 and #568 of 1291 in-ear headphones), and the Nothing Ear costs $69 against $74.99 for the Pula Unicrom, so with nothing between them on sound quality, price settles it.
The case for the Nothing Ear: A smooth response in hobbyist measurements on squig.link, at a 1.8 dB standard deviation and a preference score of 71, with every band from 20 Hz to 10 kHz within about 2 dB of target. The catch: A 6.2 dB dip near 10.5 kHz trims some top end sparkle, and a 4.5 dB peak near 7.9 kHz can add a little edge to sibilance.
The case for the Pula Unicrom: The median of 17 hobbyist measurements gives it a solid Harman preference score of 71 with a 1.92 dB spread, and its mids sit within about 0.9 dB of target, so vocals and instruments sound natural. Watch for: Its 1.92 dB spread is less even than the best measured sets.
Buy the Nothing Ear. Both are rated the same for sound quality, and it costs $5.99 less than the Pula Unicrom.
