### ⭐⭐⭐⭐⭐ Working.
*by T***D on 13 December 2025*

Working properly with 5.1 system connected to Mac mini M4 pro.

### ⭐⭐⭐⭐ Works but overpriced
*by S***S on 5 August 2025*

Works as advertised. But overpriced for what it does

### ⭐⭐⭐⭐⭐ Erfüllt direkt seine Aufgabe
*by D***L on 18 May 2026*

Der Adapter funktioniert tadellos. Ich habe ihn an einer Dockingstation hängen der das Audio Signal von einem MacBook auf einen AV Receiver schicken soll, über ein Kabellänge von 15m. Der Adapter wird direkt erkannt, Treiber oder Konfiguration sind nicht notwendig. Ich konnte in den Mac Einstellungen direkt den optischen Adapter auswählen und der Ton war direkt da wo er sein soll. Ich bin sehr zufrieden, genau die Lösung nach der ich gesucht hatte. Hier gibt es nichts zu kritisieren, absolute Kaufempfehlung.
