Multi-function Bluetooth Receiver and Transmitter with Bluetooth 5.3 and 3.5mm Interface

This multi-function Bluetooth receiver and transmitter adds wireless audio capability to devices that use a 3.5mm connection. It uses Bluetooth 5.3 and works in RX mode for receiving audio or TX mode for transmitting audio. In RX mode the 300mAh battery lasts about 6 hours, while TX mode runs for about 3.5 hours. Charging is through a Type-C interface, so no external power supply is required. The effective working radius is up to 10 metres in open areas, and the unit measures 57x33x13.5mm and weighs about 22g. It is supplied with a USB cable, a 3.5mm connector, and an instruction sheet.

Features and Construction

The adapter is built around Bluetooth 5.3 and a 3.5mm audio interface. Its small 57x33x13.5mm body and 22g weight make it easy to place near audio equipment. Power comes from an internal 300mAh battery charged via Type-C.

Material and Build

The source text lists the interface, Bluetooth standard, battery, and dimensions but does not specify the outer material. Construction details are limited to the 3.5mm interface, Type-C charging port, and internal 300mAh battery. The device is designed for audio conversion rather than for harsh environments, so normal handling is appropriate.

Size and Practical Fit

At 57x33x13.5mm and about 22g, the adapter is compact enough to sit beside a stereo or in a car without taking up much space. The 3.5mm connector allows it to link with compatible audio equipment. The 10-metre open-area working radius supports movement around a room or vehicle when conditions are clear.

Uses and Placement

This Bluetooth audio converter is intended for wired audio devices that need a wireless link. It can be used with home stereo systems or car audio through the 3.5mm interface. RX mode receives audio, while TX mode sends audio from a wired source.

Event or Professional Use

For events or professional setups, the adapter can connect a wired audio source to a Bluetooth receiver or speaker when used in TX mode. RX mode can feed a wired speaker or amplifier from a Bluetooth source. The stated range of up to 10 metres in open areas gives some flexibility in placement, though walls and obstacles may reduce that distance.

Everyday Home Use

At home, the receiver can turn a wired stereo or speaker into a Bluetooth-compatible system. The 300mAh battery supports about 6 hours in RX mode, which covers typical listening sessions. Type-C charging means it can be topped up from common USB power sources, and the compact size helps it sit discreetly near the audio equipment.

Benefits and Buying Value

The main value comes from adding Bluetooth 5.3 audio conversion to existing wired equipment without replacing it. The dual RX and TX modes cover both receiving and transmitting audio, and the rechargeable battery avoids the need for a permanent external power supply.

Reuse and Low Maintenance

Because the adapter works with a 3.5mm connection, it can extend the usefulness of wired speakers, stereos, and car audio systems. Maintenance is limited to charging through Type-C and handling the unit normally. The source text does not give specific care instructions beyond the supplied components and interface details.

Why Choose This Product

Choose this adapter if you need a compact Bluetooth 5.3 audio converter with both RX and TX modes. It offers a 300mAh battery, about 6 hours in RX mode, about 3.5 hours in TX mode, Type-C charging, and a 10-metre open-area range. The package includes the converter, USB cable, 3.5mm connector, and instruction sheet. No external power supply is required, which keeps the setup simple.
