Avantree C81

Review: Doesn’t pair / connect to any audio device - The transmitter dont pair or connect to any speaker or headphone device
Review: Possédant des AirPods Max et une PS5, n'ayant pas envie d'acheter un casque gaming car mon casque ne me sert qu'a isoler le son de mes jeux et en même temps avoir une oreille sur ce qui se passe dans la pièce, je me suis dit que j'allais chercher comment faire pour coupler AirPods / PS5. Avec un câble branché sur la manette ça fonctionne très bien mais c'est bien moins pratique. J'ai essayé un Créative MX3 qui n'a pas fonctionné, je me suis tourné vers celui-ci sans trop y croire et bien ça fonctionne très bien ! Après démarrage de la console j'ai branché le petit dongle, il a été reconnu rapidement, j'ai approché mes AirPods Max et surprise ça a fonctionné du premier coups. Au redémarrage de la console, idem le casque est reconnu directement, ce qui est bien pratique. Il n'y a qu'un seul petit bémol toutefois, si la console est en mode veille et que le dongle reste branché, le casque n'est plus reconnu sur mes autres appareils, mais bon ça ce n'est pas trop important il suffit de l'enlever après la session de jeu. En tout cas pour le moment je suis satisfait c'est exactement ce que je cherchais. A voir dans le temps...

A: Do you use the coming mic or use the built-in mic of your headphone? If you want to use your headphones’ built-in mic, double click the Multi-Function Button on the C81 and enter talk mode.
