This is a very useful device to provide Bluetooth connectivity for older stereo amplifiers, tape recorders etc, and it can be used both for input or output (switchable). The built-in amplifier is also powerful enough to drive an older set of hi-fi headphones, as a receiver for use with mobile phones, dab radios, or Wi-Fi tablets & laptops etc. The inbuilt lithium cell lasts for over 6 hours on a full charge, and charges in about 2 hours, but also the device can be operated whilst connected to the 5V charging supply. The device is very small, and a UK 50 pence coin is shown for comparison purposes in my attached photo.

I purchased a pair of this device, connected to my power amp and turn table, one as a transmitter and one as a receiver. The sound quality is excellent and it's very easy to pair.

Simple et efficace. Fonctionne parfaitement en émetteur vers un casque Bluetooth ou en récepteur pour transformer une vieille chaîne hifi en Chaine bluetooth. A vérifier: l’autonomie dans le temps. Je vais en reprendre 2 de plus. Je recommande.

Ne fonctionnait, mais le service client très réactif de Banggood m'a donné satisfaction. J'ai d'ailleurs rarement été confronté à un problème de non-fonctionnement.
