StarTech.com USB-C to 3.5mm TRRS Headphone/Headset Adapter, 5in — 32-bit DAC & Mic Support

StarTech.com's 5-inch USB-C to 3.5mm TRRS adapter converts a USB-C or Thunderbolt port into a full-featured headphone/headset jack with a built-in 32-bit DAC for high-fidelity playback and microphone support.

Many modern phones and laptops omit a dedicated audio jack; this compact dongle restores wired headset compatibility and adds a quality digital-to-analog converter (DAC) so your headphones and headsets perform as intended. The adapter supports broad sample rates and bit depths, offers clear mic input, and works across major operating systems without manual driver installs. It’s designed for everyday portability with a flexible TPE jacket and soft-touch finish.

How good is the audio quality compared with a device’s native jack?

The adapter uses a 32-bit stereo DAC and supports sample rates from 44.1 kHz up to 384 kHz, plus 16-, 24- and 32-bit audio, delivering a high dynamic range and low distortion. For microphone input, the stereo ADC provides clear voice capture suitable for calls and recordings.

• 32-bit DAC for high-resolution playback
• Output dynamic range: 105 dBA signal-to-noise ratio
• Mic ADC: 94 dB SNR, 48 kHz, 16-bit sampling
• Realtek ALC4030U chipset for reliable conversion

Will this adapter work with my phone, tablet, or laptop?

This dongle is universally compatible with USB-C and Thunderbolt hosts and works driverless across Windows, macOS, Linux, iOS, and Android. It supports headsets that use TRRS connectors and in-line controls, restoring full functionality when a native 3.5mm jack is missing.

Is the adapter durable and convenient for travel?

At 5 inches (127 mm) long, the adapter is short enough to carry in pockets or laptop bags and long enough to avoid strain on the connector. It features a flexible, durable TPE outer jacket and a soft-touch finish to resist wear and provide a comfortable grip.

• Compact 5-inch length ideal for mobile use

What can I expect when using a headset with in-line controls?

• Supports headsets with microphone and control buttons
• Media play/pause and call answer functions usually compatible
• Some advanced headset remotes may have limited support depending on host device
