BEAN Tech USB to 3.5mm Audio Adapter Dual TRS

SKU CH-813G-8K241

USB audio adapter adds dual 3.5 mm headphone and microphone ports with 16-bit/48 kHz DAC for computers and consoles

  • High-resolution DAC chip delivers 16-bit/48 kHz audio upgrade
  • Built-in DAC provides crystal-clear sound with noise reduction
  • Driver-free USB connection works instantly on Windows, Mac, Linux and consoles
  • Compact ABS housing fits in a pocket for portable use
  • Dual 3.5 mm TRS ports support separate headphone and microphone connections

What It Is

The BEAN Tech USB to 3.5mm Audio Adapter adds a stereo headphone output and a mono microphone input through a single USB port. It uses a built-in DAC to deliver 16bit/48kHz audio and works without drivers on Windows, macOS, Linux, PS5, PS4, Switch, Chromebook, Surface Pro 3 and Raspberry Pi. The compact ABS body makes it easy to carry.

Who It Suits

It suits anyone whose device lacks a working 3.5mm combo jack or needs a quick second audio interface for headsets. Buyers who require 7.1 surround output, optical S/PDIF, hardware EQ controls or a dedicated line-level output will not find those features here. The adapter also does not support PS3 consoles.

Deciding Spec

The critical figure is the 16bit/48kHz DAC resolution, which sets the maximum digital audio quality the adapter can reproduce. If your headphones or recording workflow demand higher sample rates or bit depths, this unit will not meet that requirement.

Questions about this item

Does this adapter need a separate power supply to work with my headset?

No, the adapter draws all its power from the USB port and requires no external power source.

Will my older 3.5 mm headset with separate headphone and microphone plugs connect to the dual TRS ports on this adapter?

Yes, the adapter provides two 3.5 mm TRS sockets — one for headphone output and one for microphone input — matching standard headset plugs.

After plugging it in, how can I check the adapter is running at its stated 16-bit 48 kHz capability?

Open your system sound settings, select the USB audio device, and verify the format shows 16 bit, 48 kHz.
