Portable Bluetooth 5.0 Audio Adapter

This compact 2-in-1 device adds wireless audio to non-Bluetooth equipment or upgrades wired speakers with Bluetooth reception. It connects via USB power and a 3.5 mm jack, making it suitable for TVs, car stereos, PCs and home audio systems. The CE and FCC certified unit is new and ready for everyday streaming.

Transmitter and Receiver Modes Explained

In TX mode the adapter sends audio from a TV or player to Bluetooth headphones or speakers. In RX mode it receives audio from a phone or tablet and outputs it to a wired stereo or headphones through the 3.5 mm connection. Switching modes requires a double power-cycle if the device has stayed in one mode for a while, otherwise a single restart toggles the function.

Low-Power USB Operation

The adapter draws power directly from any standard USB port, so no separate supply is needed. Bluetooth 5.0 provides a stable link with minimal energy use, keeping the unit cool and silent during extended listening sessions. Its lightweight build adds no strain to the host port.

Questions about this item

Does the adapter generate noticeable heat or noise when powered from a USB port all day?

The unit draws power from a USB port and uses Bluetooth 5.0 only, with no fan or moving parts, so it runs silently and stays cool during continuous use.

What cables must I already have to use the transmitter and receiver functions?

You need a 3.5 mm audio cable for both modes and an RCA audio cable if you want to connect the transmitter to equipment with RCA inputs.

Will the Bluetooth 5.0 link work with the older stereo system I plan to keep?

In receiver mode the adapter pairs as MSD168 and outputs analogue audio through its 3.5 mm jack, so any stereo with a 3.5 mm or RCA line input can be used.
