USB-C to 3.5mm Audio Adapter

This adapter connects a USB-C source to a standard 3.5mm stereo headphone jack. It integrates a digital-to-analog converter so devices without a native headphone socket can drive wired headphones or speakers. The 4-pole jack accepts both TRS and TRRS plugs for broad headset compatibility.

Thermals noise and power draw

The adapter draws power directly from the USB-C port and operates without a separate supply or active cooling. Passive operation means it adds no audible noise to the signal chain. Power consumption remains low enough for typical mobile and laptop hosts.

93dB SNR DAC specification

The built-in DAC delivers a 93dB signal-to-noise ratio for clean audio output. It supports 44.1, 48 and 96kHz sample rates at 16 and 24-bit depth. The ADC input handles 44.1 and 48kHz at 16-bit for microphone or line-in use. Buyers who need higher sample rates or balanced output should consider a dedicated external DAC.

Questions about this item

How do I install the USB-C to 3.5mm adapter and what step do people get wrong?

Plug the USB-C male end into the device port, then insert the 3.5mm plug fully until it clicks; the auto-switch detection only activates when the jack is completely seated.

What maintenance or replacement will the adapter need later?

The adapter has no moving parts or batteries; keep the USB-C and 3.5mm contacts clean with a dry brush and replace the unit only if the jack becomes loose or audio cuts out.

What limit appears first during sustained use?

The DAC supports up to 96 kHz at 24-bit for output and 48 kHz at 16-bit for input, so extended high-resolution playback stays within those sample-rate ceilings.
