Binary Acoustics is a Chinese in-ear monitor maker founded in 2017 around the idea of letting the ears "convey sound and emotion," with sound, minimalism and comfort as stated priorities. Little-known outside China until its Gizaudio-tuned Chopin, it has also produced sets such as the EP1D, Unicorn, VIOD, D1 and D2.

A $200 Harman-style hybrid whose clean midrange and deep sub-bass win most listeners over — and whose long, wide nozzle, mid-bass tuck and treble flavour are exactly what they argue about.

A $310 MEMS-tweeter tribrid that measures close to Harman and wins near-universal praise for detail, imaging and comfort — then splits its listeners down the middle on how much bass, how much warmth and how much vocal body that clean, airy tuning really has.
