SMUGDESK B27 Bluetooth 5.0 Audio Adapter 3.5mm

SKU CH-ZGGN-NSDS5

Adds Bluetooth 5.0 to any 3.5mm audio device as a transmitter or receiver with hands-free calling

  • Dual transmitter and receiver modes add Bluetooth to any 3.5mm audio device
  • Bluetooth 5.0 chip gives stable pairing and lossless stereo sound
  • Built-in microphone enables one-touch hands-free calls while driving
  • Universal 3.5mm AUX jack fits car stereos and home speakers
  • Compact plug-and-play design needs no drivers or complex setup

Versatile 2-in-1 Bluetooth adapter

The SMUGDESK B27 adds wireless audio to devices that lack built-in Bluetooth by working as both a transmitter and a receiver. It streams music from a phone to a car stereo or wired speakers in receive mode, and sends TV or PC audio to wireless headphones in transmit mode.

Simple 3.5mm connection and hands-free calls

A standard 3.5mm AUX jack plugs directly into most car radios, amplifiers or desktop sound systems without drivers or complicated setup. The built-in omnidirectional microphone enables one-touch hands-free calling, letting drivers answer safely while keeping the adapter permanently connected.

Bluetooth 5.0 range and single-stream limits

Bluetooth 5.0 provides faster pairing, stronger anti-interference and a longer effective connection distance for stable stereo streaming. The adapter handles one audio stream at a time, so simultaneous multi-device playback or high-bitrate codec negotiation beyond the core specification is not supported.
