SMUGDESK 2-in-1 Bluetooth 5.0 Audio Adapter 3.5mm AUX Transmitter Receiver

SKU CH-88CD-PX2JH

Wireless 3.5 mm AUX adapter adds Bluetooth 5.0 streaming to speakers or headphones in a compact, rechargeable design

  • Wireless audio streaming from phone to car stereo via Bluetooth 5.0 receiver mode
  • Bluetooth 5.0 transmitter sends TV sound to wireless headphones without cables
  • 5 mm AUX jack fits speakers, headphones, televisions and car audio systems
  • Compact mini body travels easily for home, vehicle and portable use
  • Rechargeable battery powers long listening sessions after a single charge

Portable Wireless Audio Adapter

The SMUGDESK 2-in-1 Bluetooth 5.0 audio adapter adds wireless capability to wired sound systems through a single 3.5mm AUX connection. It functions as both a transmitter and a receiver, allowing non-Bluetooth sources to stream to wireless headphones or wired speakers to receive audio from mobile devices.

Home and Vehicle Audio Upgrades

This adapter suits listeners who want to stream music from a phone to an older car stereo or home speaker system without cables. It also fits users who wish to watch late-night television through Bluetooth headphones. Buyers needing aptX Low Latency codec support, multi-point pairing, or optical digital audio connections should consider alternative solutions.

Dual Mode 3.5mm Connectivity

The defining specification is the 2-in-1 design combining transmitter and receiver roles in one unit switched by a single button. A 3.5mm AUX jack and included audio cable provide the physical link for both modes, while the upgraded Bluetooth 5.0 chip handles the wireless link. This specific combination of dual-mode versatility and analogue connectivity determines whether the adapter matches the user's equipment.
