USB-C to 3.5 mm Audio Adapter Pack

This two-pack supplies USB-C to 3.5 mm audio adapters for phones and tablets that lack a built-in headphone jack. Each unit contains an integrated DAC chip with noise-reduction circuitry. The adapters suit users who want wired headphones or a headset for music and calls on modern USB-C devices.

USB-C Audio Interface Limits

The adapters rely on the host device to deliver digital audio over USB-C; they cannot add analogue output to ports that only carry data or charging. Audio quality and volume depend on the source device’s DAC implementation and software volume control. In-line remote functions such as play, pause and call answer work only when the connected headset and the host operating system both support the same wire-control protocol.

Plug-and-Play Installation

No driver installation is required on supported phones, tablets or laptops; the adapters are recognised automatically when inserted. The braided cable and reinforced strain relief are rated for over 5000 bend cycles, reducing the risk of cable fatigue. The most common issue is a loose fit in recessed or worn USB-C ports, which can cause intermittent audio or remote-control failure.

Questions about this item

Should I pick the single or the 2-pack version?

The listing is a 2-pack, giving you two identical grey adapters so you can keep one at your desk and one in your bag.

What does the built-in DAC chip actually do for my headphones?

The integrated DAC converts the phone's digital signal to analogue, providing noise reduction and high-resolution audio without needing any driver install.

Does the USB-C plug carry audio only or also charging?

This adapter is audio-only; it passes the 3.5 mm headset signal through the USB-C port but does not support power delivery or data.
