Bluetooth 5.0 Audio Adapter

The BAISHUN CJX-C027-BK adds Bluetooth 5.0 connectivity to non-Bluetooth devices such as TVs, PCs, vintage stereos, speakers and car audio systems. It operates in two modes: transmitter mode sends audio from a wired source to wireless headphones or speakers, while receiver mode streams audio from a phone or tablet to a wired sound system. A built-in LCD screen displays the active mode, pairing status, connected device name and volume level. The unit is powered via a DC 5 V supply.

32 GB TF Card Playback and 10 Metre Range

In receiver mode the adapter accepts a TF card up to 32 GB for direct music playback without a paired device. Audio connections are provided through RCA left/right outputs and a 3.5 mm AUX jack for broad compatibility with home stereos, car stereos, projectors and portable players. Bluetooth 5.0 delivers a working range of 33 ft (10 m) in open space. The adapter supports the A2DP profile for stereo audio streaming and requires no driver installation for plug-and-play use.

Compact Low-Power Design

Measuring 2.63 in by 2.59 in by 0.82 in and weighing 0.105 kg, the device fits easily into tight spaces behind a TV, in a car centre console or on a desktop. It draws power from a standard DC 5 V source such as a USB charger or vehicle port, so no high-wattage supply is needed. The LCD screen provides clear status information without adding noticeable heat or fan noise, keeping operation silent in living rooms, bedrooms or vehicles.

Questions about this item

Will the CJX-C027-BK connect to my older car stereo that only has RCA inputs?

Yes, the adapter supports RCA L/R output in receiver mode so you can pair your phone via Bluetooth 5.0 and play audio through the stereo's RCA jacks.

How do I confirm the adapter is paired and in the correct mode after I plug it in?

The built-in LCD screen displays the active mode (Tx or Rx), pairing status, connected device name and current volume level.

Does the package include a TF card or do I need to buy one separately for music playback?
