CROSTALK

Music heard through one ear isn't stereo. It's half a mix, half the spatial experience, half the music. CROSTALK was built by a lifelong musician who lost stereo hearing overnight and refused to lose his music. It's a personal audio processor for people who hear from one side, and it does one remarkable thing by creating the illusion of stereo audio. The width comes back. The soundstage comes back. Your music comes back. This is the free companion app that puts it under your control. Hearing, your way. THE MIRROR CONTROL The heart of CROSTALK. Slide it to pull the far side of the mix toward the ear you favor. The stereo image is expanded back into balance. Guitars panned away from you return. Harmonies you've been missing show up again. THE MIXER A real four-channel mixer including control for: MIC, LEFT, RIGHT, MEDIA. With intuitive faders, meter, and mute on every channel, plus playback controls. Built like audio gear, with simplicity first. CHANNEL EQ Bass, mid, and treble, shaped per channel. Sync it or sculpt each side on its own. FAVES Your sound isn't one setting. Save profiles for the places you live your life. Speech and Music are ready out of the box, with custom slots you can name and switch with one tap. SETUP WIZARD A short first-run setup plays soft tones in each ear and tunes CROSTALK to you. Retake it anytime. DSP EFFECTS Compression, De-Noise, and Loudness. Each with its own amount control, each yours to dial in. FIRMWARE UPDATES Your CROSTALK gets better over time. Updates ship right from the app over Bluetooth. DEMO MODE No CROSTALK yet?
