2-in-1 Bluetooth 5.0 Audio Transmitter and Receiver Adapter for TV, Car and Home Stereo

This 2-in-1 Bluetooth 5.0 audio transmitter and receiver adapter is a compact wireless audio solution for sending sound between wired and Bluetooth devices. In transmitter mode, it takes audio from a non-Bluetooth TV, home stereo system or CD player and sends it wirelessly to a Bluetooth headset or speaker. In receiver mode, it takes audio from a Bluetooth-enabled mobile phone, tablet or computer and sends it to a wired stereo, speaker or headset. A single press of the switch changes between the two modes, so one adapter can cover more than one audio setup. It measures 44 × 44 × 12mm, weighs 18g and carries a 200mAh lithium polymer battery that charges in 2 hours. The operating range is up to 10m (33ft) without obstruction.

Features and Construction

This section sets out the main hardware facts stated in the source data, including Bluetooth version, supported profiles, battery type and the physical size of the adapter. It covers what the device is made from, how it is measured and what the black metal housing means in practice for placement and carrying. No waterproofing, dust resistance or codec details are stated in the source, so those points are not included here.

Material and Build

The adapter is described as bare metal with a black finish and overall dimensions of 44 × 44 × 12mm. Its 18g weight makes it light enough to sit on a desk, shelf or car console without adding noticeable bulk. The metal housing gives the unit a solid feel, but the source does not state any impact rating, corrosion resistance or weatherproofing, so it should be kept dry and used indoors or in a protected area. The black colour is the only option listed. The micro USB power cord, RCA cable and 3.5mm auxiliary cable are all included for connection.

Size and Practical Fit

At 44 × 44 × 12mm, the adapter is small enough to fit in a backpack or laptop bag alongside other accessories. The 10m (33ft) operating range is measured without any obstruction, so walls, furniture and other solid objects may reduce that distance in real use. The 200mAh lithium polymer battery is charged through the micro USB port in 2 hours. Because no standby time, playback time or charging input voltage is given in the source, those figures are not claimed. The pairing name is kn321, which is the name that appears when a Bluetooth device searches for it.

Uses and Placement

This section looks at the practical situations the adapter is designed for, based on the transmitter and receiver modes described in the source. It covers event or professional use, everyday home use and how the included cables support each scenario. The focus stays on the supported audio connections rather than any sound quality claims, as no audio performance data is provided.

Event or Professional Use

In transmitter mode, the adapter can send audio from a non-Bluetooth TV, home stereo system or CD player to a Bluetooth headset or speaker. This suits situations where a wired source needs to reach a wireless listener, such as a presentation, a temporary setup or a room where running cables is not practical. In receiver mode, it can take audio from a Bluetooth-enabled phone, tablet or computer and send it to a wired stereo, speaker or headset. A single press changes the mode, so the same unit can be moved between roles without extra hardware. The included 3.5mm and RCA cables cover the wired connections needed for these setups.

Everyday Home Use

At home, the adapter can connect a computer, laptop, home stereo system, headset, smartphone, MP3 player or CD player, depending on which mode is selected. The 44 × 44 × 12mm size means it can sit near a television, hi-fi unit or desk without taking up much space. The 10m (33ft) unobstructed range allows some freedom to move around a room while listening through a paired Bluetooth headset or speaker in transmitter mode. The 2-hour charge time and 200mAh battery are the only power details supplied. No remote control, app or voice assistant support is mentioned in the source.

Benefits and Buying Value

This section explains the practical value of the adapter using only the features stated in the source, such as mode switching, cable compatibility and portability. It avoids price comparisons, durability claims and performance promises that are not supported by the product information. The aim is to show where the adapter fits into an existing audio setup and what is included in the box.

Reuse and Low Maintenance

The 2-in-1 design means the adapter can be used as either a transmitter or a receiver, so one unit can serve two different audio chains. Switching modes requires only a press of the switch, with no need to remove or reconnect the device. The black metal housing can be wiped with a dry cloth when needed, but the source gives no specific cleaning or maintenance instructions, so harsh liquids and immersion should be avoided. The rechargeable 200mAh lithium polymer battery removes the need for disposable batteries, and the micro USB power cord is included for charging.

Why Choose This Product

This adapter is a practical choice for anyone who needs to move audio between non-Bluetooth and Bluetooth devices without replacing existing equipment. It supports Bluetooth 5.0 with A2DP and AVRCP in receiver mode only, has a pairing name of kn321 and works within an unobstructed range of up to 10m (33ft). The package includes the adapter, a micro USB power cord, an RCA cable, a 3.5mm auxiliary cable and a user manual, so the main connection leads are supplied. Buyers should note that the source does not state waterproofing, codec support beyond A2DP and AVRCP, multipoint pairing or warranty terms.
