Emax Wireless, Inc. USB-C to 3.5mm Audio Adapter accessory

USB-C to 3.5 mm Adapter for Mobile Devices

This compact adapter connects wired headphones to USB-C smartphones and tablets that lack a built-in jack. It targets commuters, students and office workers who want to keep using existing analogue headsets for music and calls without carrying a separate Bluetooth headset. The inline remote supports playback control and call handling on compatible handsets.

Integrated DAC Handles Stereo Playback and Voice

A built-in digital-to-analogue converter translates the phone's digital output into an analogue signal for standard 3.5 mm plugs. It drives typical in-ear and on-ear headphones at normal listening volumes for music, podcasts and phone conversations. Very high-impedance studio headphones or multi-driver in-ear monitors may not reach desired loudness because the adapter's output stage is designed for mobile-level loads.

Passive Cable Runs Cool and Silent

The 12 cm copper-core cable draws power directly from the host device and adds no active electronics beyond the DAC, so it produces no audible noise and remains at ambient temperature during use. Current draw is negligible compared with the phone's own audio subsystem, leaving battery life effectively unchanged. The aluminium-foil shield resists everyday bending and corrosion without adding bulk.
