Multi-function Bluetooth Receiver with Bluetooth 5.3, 3.5mm Interface and Type-C Power

This multi-function Bluetooth receiver and wireless audio converter is built for adding Bluetooth 5.3 connectivity to audio equipment that uses a 3.5mm connection. It can work in RX mode to receive audio from a phone, tablet or other Bluetooth source, or in TX mode to send audio from a non-Bluetooth device to Bluetooth headphones or speakers. The unit measures 57x33x13.5mm and weighs about 22g, so it is small enough for a desk, shelf, car interior or stereo cabinet. Power comes through a Type-C interface, and the built-in 300mAh battery gives around 6 hours in RX mode and around 3.5 hours in TX mode. The open-area transmission distance is up to 10 metres.

Features and Construction

The main hardware details are stated clearly in the source data: Bluetooth 5.3, a 3.5mm interface, Type-C power input, a 2.4Mbps transmission rate and a 20MHz operating frequency. These specifications define what the unit can connect to and how it should be powered, without needing guesswork about extra features.

Material and Build

The source text does not list the exact housing material, so the description stays with the confirmed hardware. The 3.5mm interface supports wired audio connections, while the Type-C interface is used for power. The unit has a 300mAh battery and a stated weight of about 22g. No external power supply is required, which simplifies placement near audio equipment. The converter is supplied with a USB cable, a 3.5mm connector and an instruction sheet.

Size and Practical Fit

At 57x33x13.5mm, the converter occupies very little space. Its 22g weight means it can sit discreetly behind a speaker, beside a receiver or inside a car without adding noticeable bulk. The effective working radius is up to 10 metres in open areas, which supports normal room-to-device use where there is a clear line of sight. The compact footprint also makes it easy to move between locations when needed.

Uses and Placement

The product is intended for audio conversion where one device uses Bluetooth and another uses a 3.5mm wired connection. The two operating modes cover both directions: receiving Bluetooth audio for a wired speaker system, or transmitting audio from a wired source to Bluetooth headphones or speakers. The Type-C power method and built-in battery make it suitable for temporary setups as well as fixed installations.

Event or Professional Use

For events or temporary audio setups, the 10m open-area range and dual RX and TX modes allow quick connection between Bluetooth sources and wired sound equipment. The 300mAh battery supports around 6 hours in RX mode or around 3.5 hours in TX mode, which can cover shorter sessions. The small 57x33x13.5mm body can be placed near a mixer, speaker or display without taking up much room.

Everyday Home Use

At home, this converter can add Bluetooth 5.3 to a wired speaker, hi-fi system or other audio device with a 3.5mm input. In RX mode it receives audio from a phone or tablet, while in TX mode it sends audio from a non-Bluetooth device to Bluetooth headphones. The Type-C interface makes charging straightforward, and the 22g weight keeps the unit unobtrusive on a shelf or desk.

Benefits and Buying Value

The practical value comes from the combination of Bluetooth 5.3, dual RX and TX modes, a 3.5mm interface and Type-C power in a small 57x33x13.5mm unit. The stated battery performance gives clear expectations for RX and TX use, and the included accessories mean the converter can be set up without needing extra parts beyond what is supplied.

Reuse and Low Maintenance

By converting audio between Bluetooth and a 3.5mm wired connection, the unit can help existing audio equipment stay in use rather than being replaced. Recharging is done through the Type-C interface, and the 300mAh battery supports around 6 hours in RX mode or around 3.5 hours in TX mode. The source text does not state specific cleaning or maintenance methods, so care should follow the instruction sheet supplied with the product.
