#25 Aoshida E20: $22.99 Amazon eBay
Pros: Across six hobbyist measurements on squig.link, the E20 reaches a preference score of 82.6 with a smooth 1.13 dB deviation from target. Sub-bass sits within a decibel of target down to 30 Hz, and the mids stay within about 1 dB, so vocals sound natural with solid bass underneath. Its dual dynamic driver design and budget price make it a sensible pick for warm or mildly V shaped tastes.
Cons: A 6 dB peak near 8.4 kHz and treble about 2.1 dB above target from 6 to 10 kHz can make sibilance and hi hats sound sharp on bright recordings. Bass from 60 to 200 Hz runs about 1 dB lean, so it has less punch than bass focused alternatives. It is rated level with similarly priced rivals such as the KZ EDZ and DDHiFi Janus 3 rather than above them.
