I/O Audio

I/O Audio is a Shenzhen in-ear monitor brand that appeared in April 2024 and launched at the top of its own range with the Volare, a nine-driver tribrid combining a custom dynamic driver, four balanced armatures and four Sonion electrostats. Its shells are 3D-printed by HeyGears, and its products are distributed by Shenzhen Audio; a second model, the Sogno, followed. The name is styled inconsistently across its own packaging and its reviewers — I/O Audio, I\O Audio, IOAUDIO and I/O Acoustic all refer to the same company.
