UGREEN Bluetooth 5.4 Transmitter Receiver - Dual Pairing 2-in-1

Our review of the UGREEN Bluetooth 5.4 Transmitter Receiver finds it best suited for travelers and anyone with older audio gear who wants a simple way to add wireless audio. The clear stand-out is its 2-in-1 design that switches between transmitter (TX) and receiver (RX) modes, so a single adapter turns a TV or airplane audio jack into a wireless source or converts a car stereo and old speakers into Bluetooth-ready targets. The compact, retractable-cord housing and built-in microphone make it convenient for in-car hands-free calls and portable listening without extra clutter.

Key Features

• 2-in-1 TX/RX: Works as a transmitter to send audio from non-Bluetooth devices to wireless headphones and as a receiver to add Bluetooth playback to car stereos and home speakers.
• Bluetooth 5.4: Uses the latest Bluetooth 5.4 technology for lower latency and clearer audio, helping keep audio and video more closely synchronized.
• Dual Pairing: Connects two Bluetooth headsets or earbuds at once so two people can listen to the same source simultaneously.
• Built-in Microphone: Lets users answer calls hands-free while the device is connected to a phone and playing music, avoiding the need to disconnect audio playback.
• Retractable Spring Cord: The retractable cable stores neatly and adjusts length automatically, making the adapter easier to carry and position in a car or bag.
• LED Display: Provides a simple readout of mode or connection state so users can confirm TX or RX operation at a glance.

Who It's For

This adapter is ideal for frequent flyers and commuters who need to connect modern Bluetooth headphones to in-flight entertainment or TVs without Bluetooth. It is also a good match for owners of older car stereos and home speaker systems who want to stream music from a phone or laptop without replacing their equipment.

Those who need studio-grade wireless performance, precise audiophile tuning, or multiroom speaker integration should look elsewhere; the UGREEN is focused on practical wireless conversion, portability and convenience rather than professional audio features.
