#113 EarSonics ES2: $289.99 Amazon eBay
Pros: Two balanced armature drivers and a very high 119 dB/mW sensitivity mean it reaches loud levels from any phone or dongle with little effort. The closed in-ear design isolates well from outside noise.
Cons: Crinacle’s measurement gives it a preference score of only 29, one of the furthest from the Harman target among in-ears, so its tonal balance will sound off to most listeners without EQ. The Oriolus Finschi Hifi rates higher and costs less, and the Westone W20 matches its rating for less money.
