接続の安定性が高い

本機をパソコンの3.5ジャックに繋ぎ、bose　QuietComfort Ultra Earbudsをペアリングして壁厚３００ミリの隣の部屋に移動しても接続が不安定になったり、音が途切れたりすることはありませんでした。また、音ズレは全く気になるレベルではありませんでした。

Easy to set up!

What a great product for the bedroom. Bought this for me and the wife and a couple of bluetooth headphones so that after the kids are in bed we can watch some TV together without having to worry about the volume waking the kids up.It does come with instructions but there is a qr code right ontop of the box and it walks you through the steps so simply I can't imagine having a hard time setting it up. It did take me a few minutes as I am not the most tech savvy person but again the instructions were super easy to follow!

Świetny

Działa jak powinien, dźwięk super jakości na coxial złączu, nie zrywa, nie zauważyłem opóźnienia w stosunku do wyświetlanego obrazu. W końcu mogę wieczorem oglądać filmy na odpowiedniej głośności, nie przeszkadzając przy tym innym domownikom. Dla starszych TV bez BT rewelacja.
