Ich habe mir den Adapter primär für die Nutzung auf Langstreckenflügen zugelegt. Mein Fazit nach 2 Mittel- (> 3 Std.) und 3 Langstreckenflügen (> 8 Std.): Top! Für mich ist es ein Gamechanger, endlich meine Bluetooth-Kopfhörer (JBL Live Pro 2) mit dem Bordentertainment verbinden zu können - um einerseits Filme in besserer Tonqualität genießen zu können, aber auch eventuelle Störgeräusche ausblenden zu können. Folgende Kriterien waren entscheidend dafür, dass ich mich für den Avantree Relay entschieden habe: - lange Akkulaufzeit: wird mit ca. 20 Stunden angegeben. Kombi aus Mittel- und Langstrecke mit in der Summe je 14-18 Stunden hat das Gerät anstandslos mitgemacht! - schnelles Wiederaufladen: wird mit ca. 20 Minuten angegeben. Ich habe keine Stoppuhr gestellt, aber es geht wirklich verdammt schnell, bis das Gerät wieder einsatzberei ist, nachdem der Akku leer war. - Low Latency-Unterstützung: Ich war im Vorfeld etwas skeptisch, da ich immer wieder von Verzögerungen bei der Ton- im Vergleich zur Bildübertragung gelesen habe. Um diese zu vermeiden, müssen sowohl Bluetooth-Adapter als auch Kopfhörer diese Funktion unterstützen. Bei mir hat das mit dem Avantree in der Kombi mit dem JBL Live Pro absolut einwandfrei funktioniert! - Design und Funktionen: ich empfinde es als praktisch, dass man auch am Adapter eine Möglichkeit zur Lautstärkeregulierung hat. Allgemein ist der Adapter nicht nur klein und leicht, sondern wirkt auch wertig verarbeitet und ist intuitiv bedienbar. In blau passt er sogar farblich zu meinen Kopfhörern! Das war zwar kein Kriterium, ist aber trotzdem nett ;-) Der Artikel war gut verpackt und der Lieferumfang umfasst neben dem Adapter selbst auch noch ein Ladekabel und einen Dual-Aux-Adapter, dazu noch ein kleines Täschchen, in dem sich alles für die Reise perfekt verstauen lässt. Von mir eine klare Kaufempfehlung - ich bin wirklich sehr zufrieden.
