3.5mm Bluetooth 5.4 Receiver Transmitter Adapter for Car and Home Audio

This 3.5mm Bluetooth adapter offers two-in-one functionality, acting as both a receiver and a transmitter. It allows audio equipment that lacks built-in Bluetooth, such as a car stereo or wired speaker system, to send or receive audio wirelessly. The adapter uses Bluetooth 5.4, operates at 2400 MHz, and has a transmission rate of 100 Mbps. With an effective working radius of 10 metres, it supports flexible placement in a vehicle or room. It is plug and play and requires no external power supply, so setup involves connecting the 3.5mm plug to a compatible aux port. The package includes one receiver transmitter unit.

Features and Construction

This section covers the main functional elements and physical interface of the adapter, based on the available product information.

Two-in-One Function

The adapter works as both a receiver and a transmitter. In receiver mode, it can accept Bluetooth audio and output it through the 3.5mm connection. In transmitter mode, it can take audio from a device with a 3.5mm output and send it to a Bluetooth receiver. This dual function means one unit covers two common audio routing needs. The Bluetooth 5.4 standard is used, and the operating frequency is 2400 MHz. The transmission rate is listed as 100 Mbps.

3.5mm Interface and Plug and Play

The 3.5mm interface is a common audio connection found on car stereos, portable speakers, and home audio systems. The adapter is plug and play, so it does not require software installation or an external power supply. You connect it to the 3.5mm aux port of your audio equipment, and it is ready for use within the stated Bluetooth working range. No additional power cable is needed, which keeps the setup simple.

Uses and Placement

This part outlines typical situations where the adapter can be used, using only the details provided in the source text.

Car Audio Use

In a car, the adapter can connect to the vehicle's 3.5mm aux input. This allows a phone or other Bluetooth device to send audio to the car stereo, or it can transmit audio from a non-Bluetooth car media player to a Bluetooth speaker or headset. The effective working radius of 10 metres is more than enough for use inside a vehicle. The plug-and-play design means no external power supply is required.

Home and Wired Audio Use

At home, the adapter can connect to wired speakers, amplifiers, or other audio gear with a 3.5mm port. It can receive audio from a Bluetooth phone or tablet, or transmit audio from a wired source to a Bluetooth receiver. The 10-metre working radius supports normal room-to-room placement. Because it is plug and play, no external power supply is needed.

Benefits and Buying Value

This section summarises practical advantages that are directly supported by the product information.

Single Unit for Two Functions

Having both receiver and transmitter functions in one unit reduces the need for separate adapters. The 3.5mm connection is widely used, so the adapter can work with a range of audio devices that have a matching port. The Bluetooth 5.4 standard and 100 Mbps transmission rate are stated specifications. The 10-metre effective working radius gives flexibility in car or home settings.

Simple Setup and Low Maintenance

The adapter is plug and play and needs no external power supply. This means there are no extra cables or power adapters to manage. Setup consists of plugging the 3.5mm connector into a compatible audio port. The package includes one receiver transmitter unit. For care, keep the adapter dry and avoid force when inserting or removing the 3.5mm plug, as no specific maintenance instructions are provided.
