Short answer: a tie on sound quality. Both are rated 3.1/5 (#962 and #979 of 1291 in-ear headphones) at nearly the same price ($2,000 vs $1,999), so choose on features and fit.
Why pick the HIFIMAN RE2000 Pro: A single dynamic driver in-ear with a preference score of 63 in crinacle’s measurement, close to the similarly priced 64 Audio U18S in rating. The catch: Its response deviates about 2.9 dB from target on average, so its tuning is noticeably uneven for the money.
The case for the Ice Lab Spectrumica: Bass is lifted about 2.7 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The catch: Presence sits about 6 dB low with an 8.2 dB dip near 3.5 kHz, so vocals and instruments lose some bite.
Buy the HIFIMAN RE2000 Pro or the Ice Lab Spectrumica on features: they are rated the same for sound quality at close to the same price.
