#9 EPZ G20: $49.99 Amazon eBay
Pros: The G20 is one of the most accurate inexpensive in-ears measured, with a preference score of 86 and under 1 dB of unevenness in the median of twelve hobbyist measurements on squig.link. Bass, midrange and lower treble all land within about 1 dB of target, and sub-bass stays full down to 20 Hz. It matches the rating of the costlier Truthear Zero Blue 2 and includes an inline microphone.
Cons: A 6.3 dB peak near 11.9 kHz adds extra air that can make some recordings sound a little hissy or splashy. The EPZ Q1 Pro earns the same rating for a bit less money, and the 100 dB sensitivity figure is unremarkable, though still fine for a phone.
