Short answer: the Binary Chopin. It ranks #83 of 450 in-ear headphones by sound quality, rated 4.5/5, at $299.99; the Etymotic EVO ranks #114, rated 4.4/5, at $298.98. The price gap is small enough that the sound-quality ranking should decide it.
What the Etymotic EVO does well: Three balanced armature drivers deliver a flat, uncolored midrange, with the 1 to 3 kHz region within 0.5 dB of the Harman target and a preference score of 78. The tradeoff: Bass is lean, with sub-bass about 3.3 dB under target and the 60 to 200 Hz region 1.5 dB under, so kick drums and bass lines have less weight than most listeners prefer.
Buy the Binary Chopin. It is rated higher for sound quality, and the $1.01 saving on the Etymotic EVO is not enough to make up the difference.

Etymotic EVO: $298.98 Amazon eBay
Pros: Three balanced armature drivers deliver a flat, uncolored midrange, with the 1 to 3 kHz region within 0.5 dB of the Harman target and a preference score of 78. Response is smooth, with a standard deviation of 1.89 dB around target. The deep-insertion wired design is passive noise isolating, and the 47 ohm impedance still works from a phone or dongle.
Cons: Bass is lean, with sub-bass about 3.3 dB under target and the 60 to 200 Hz region 1.5 dB under, so kick drums and bass lines have less weight than most listeners prefer. Treble from 6 to 10 kHz is about 3.5 dB low and the response drops 7.4 dB near 11.9 kHz, which makes cymbals and air sound dull. Sensitivity of 99 dB at 0.1V is modest, so volume needs more headroom than the most efficient earphones.
