CROSTALK is a personal audio processor for people who hear from one side. If you listen with one ear, music and movies collapse into a flat, one-sided image, half the mix gone. CROSTALK creates the illusion of stereo audio, and you set the balance across a full, natural soundstage.

Mirror is CROSTALK's signature control. Not balance, not fade: it brings the far channel across to the ear you favor, on a dial you set. You find your own balance, and the illusion of stereo audio takes shape around it.

Built by a lifelong musician who lost stereo and refused to lose his music, every CROSTALK pairs a transparent, low-latency mic preamp (natural sidetone, ambient awareness) with a free app that lets you shape the mix, build profiles for any room, and switch on the fly. Start with CROSTALK itself, or go complete with the CROSTALK Bundle.

Not a hearing aid. Not balance or fade. Hearing, your way.
