Short answer: the EarFun Air Pro 4, if you are buying new. The EarFun Air Pro 2 ranks higher than it (#302 vs #735 of 1490 in-ear headphones, 4.3/5 vs 3.7/5) but is discontinued, so only consider it used; the EarFun Air Pro 4 is still sold new at $53.16.
The EarFun Air Pro 2 is the better-sounding choice. Budget wireless ANC earbuds with a preference score of 77 and bass boosted about 3 dB down to 20 Hz. Watch for: A 5 dB peak near 9.4 kHz adds some sizzle, and the warm tilt (minus 0.56) can sound heavy.
The EarFun Air Pro 4 is the longer-running option. The median of 5 hobbyist measurements gives it a solid Harman preference score of 70 with a 2.30 dB spread, and its mids sit within about 0.7 dB of target, so vocals and instruments sound natural. It is rated for 11 hours of battery against 7 for the EarFun Air Pro 2. It supports LDAC Bluetooth, which the EarFun Air Pro 2 lacks. Watch for: Its 2.30 dB spread is less even than the best measured sets.
Buy the EarFun Air Pro 4 if you want one new; the EarFun Air Pro 2 is discontinued, so only look for it used.
