Avantree Audikast 3 - Bluetooth 5.3 TV Audio Transmitter with Enhanced Optical Volume, 100ft Range Long Range, Dual Connection - Universal Bluetooth Device Compatibility

Review: FACIL, RAPIDO, CONEXION ESTABLE ;) - llevo 1 mes con el dispositivo, y muy contento. FINALMENTE SE PUEDEN CONECTAR 2 AURICOLARES A LA VEZ, UNA ALEGRIA ! Se instalò en un momento, y de momento no ha dado ningun tipo de fallo. Es mas, es la primera vez que los cascos tienen un alcanze mas lejos de siempre... PERFECTO
Review: Ausgereiftes Qualitätsprodukt - Bei einem vergleichbaren, etwas günstigeren, ebenfalls namhaften Kokurrenzprodukt gab es mit meinen Kopfhörern alle paar Minuten Verbindungsabbrüche. Ein Firmeware-Upgrade wurde dort nicht angeboten. Anders hier. Eine mittels QR-Code am Produkt erreichbare, sehr gute Online-Anleitung (auch als PDF erhältlich) führte sehr einfach u. a. in deutscher Sprache Schrtt für Schritt durch die Inbetriebnahme und gab gleich zu Beginn den dringenden Hinweis auf die sinnvolle und unkomplizierte Installation (Windows + MacOS) eines möglichen Fimeware-Upgrades. Nach dessen Installation funktionierte alles wunderbar. Problemloses Pairing und keine Verbindungsabbrüche über Stunden bis zur Erschöpfung der Akkus in den Kopfhörern. So soll es sein. Die Kabel sind gut brauchbar - solider als beim Konkurrenzprodukt. Achtung: Das Gerät hat keinen Akku, benötigt also eine USB-Buchse zur Stromversorgung. Ich hatte das vorher gewusst und mich bewusst dafür entschieden, weil ich Wegwerfprodukte mit fest verbautem (nicht austauschbarem) Akku verabscheue. (Die Akkus in Handy und Kopfhörern von Fairphone kann ich nachkaufen und selbst austauschen.) Ladebuchsen sollte es in jedem Haushalt ausreichend geben, und bei Bedarf tut es auch eine Powerbank. ;-)

## Features
