What it is and who it’s for

This USB-C to 3.5 mm audio adapter lets you connect wired headphones or an aux cable to devices that lack a built-in headphone jack. It is aimed at listeners who want to keep using analogue headsets with recent smartphones, tablets or laptops that only provide a USB-C port.

Practical limits of the USB-C audio interface

The adapter relies on the host device to support audio output over USB-C; some phones or tablets do not implement this mode and will not produce sound. It carries analogue stereo only, so multi-channel or high-bitrate digital streams are not possible through this connection.

Installation and common issues

Plug the dongle into the USB-C port and attach your 3.5 mm headphones — no driver or software is required. The most frequent problem is a host that does not recognise the adapter, which usually means the device’s USB-C implementation does not support audio accessory mode.

Questions about this item

Should I choose this adapter or a different version for my USB-C device?

This single adapter works with the listed iPhone 16, 15, iPad Pro, MacBook, Galaxy S24, S23, S22, Pixel and OnePlus models, so no other version is needed.

What does the 12000 bending-test rating mean for daily use?

The relief-strain design survived over 12000 bends in testing, so the cable resists wear from frequent plugging, unplugging and pocket storage.

Does the USB-C plug carry analogue audio or digital, and what limits the sound quality?

The built-in DAC chip converts digital USB-C audio to analogue 3.5 mm output, so quality depends on the chip and your headphones, not on the phone’s internal DAC.
