音声の途切れ、ノイズ

投稿者名Reviewed by：tar0 【埼玉県】

Apt X LLが使える普及価格帯のイヤホンは現状これくらいしかないので買いました。

Apt X LLならではの低遅延は良いのですが、Bluetooth接続の品質がかなり悪い（弱い）です。

切れることはありませんが、トランスミッターから1mくらいの近距離でもノイズや音の途切れが発生します。トランスミッターとの間に自分の腕や肩が入るだけで音が途切れます。
同条件で他のBluetoothイヤホンと比べても、圧倒的に弱いです。

ぜひ改善してほしいところです。

画期的な製品だとは思うが

投稿者名Reviewed by：h87108610 【愛媛県】

もともと有線だったイヤホンをBluetoothで使用できるのは非常にいいと思う。遅延も大して気にならず、音質の変化も感じなかった。
ただ接続の不安定さにはイライラさせられている。
5分に10回のペースで音が途切れたりノイズが走ったりするので、聴いていて非常にイライラする。
普段ストレス発散のために音楽を聴いてるが、これでは自分の胃とイヤホンのどちらが先に駄目になるか気が気でない。
自分が運悪く不良品を掴まされただけかもしれないが、ネックレスとしては良いデザインをしているので、少々高いアクセサリーとしては十分な商品ではないだろうか。
