2 In1 Bluetooth 5.3 Transmitter Receiver Adapter 3.5mm AUX Jacks for Car Speakers Audio Music Receiver Handsfree Headset

It works as described and reliably. Operation is simple and convenient. The quality of the design corresponds to the low price. I appreciate that a pair of these adapters are capable of pairing together, so that two adapters can be used as a wireless replacement instead cable between two devices, neither of which is originally equipped with bluetooth capability (see photo). Unfortunately, the quality is incomparable with good cabel. The use of these adapters is not suitable for concentrated listening quality music signal. However, for casual listening without higher demands or for listening to spoken speech, it can definitely be recommended. Information about some of hree LEDs is missing (indication when discharged, during charging, after full charged the battery ...)
