Connect 3.5 mm headsets via USB

This BUCIER adapter adds a stereo headphone jack and a microphone jack to any device with a free USB port. It supports 16 bit audio at 44.1 kHz or 48 kHz sampling rates and drives headphones from 16 to 600 ohms. The unit measures 3.16 in by 2.78 in by .83 in and works with Windows, Linux, macOS, iOS, Android and PS5.

Volume and bass controls on the unit

A master volume knob and a bass adjustment knob sit on the adapter itself, letting you change output level and low-frequency response without opening software mixers. The package includes a USB cable and a user manual so the hardware is ready to use straight from the box.

Driver-free setup with one-way audio path

Plug the adapter into a USB port, connect a single 3.5 mm headset that combines headphone and microphone signals, and the operating system recognises it immediately. Audio travels only from the USB port to the 3.5 mm ports, so the device cannot capture line-level input or work with separate headphone and microphone plugs. It also does not function with PS3, Xbox, TVs, amplifiers, car systems or Audacity.

Questions about this item

Will the volume and bass knobs or the 3.5 mm jacks wear out and need replacing?

The adapter has no user-replaceable parts; the knobs and jacks are soldered to the board, so any failure means replacing the whole unit.

What limits continuous use — does the USB-C power port overheat or the headphone amp clip first?

The USB-C port only supplies charging power; the headphone amp drives 16–600 Ω loads at 16 bit / 44.1 or 48 kHz and will clip before the port overheats.

How much heat or fan noise appears when the adapter runs all day?

There is no fan and the aluminium case stays barely warm because the circuit draws only the USB bus power needed for 16-bit stereo playback.
