### ⭐⭐⭐⭐⭐ 簡単
*by ゆ***ん on July 14, 2025*

簡単！すぐ使えました。

### ⭐⭐⭐⭐⭐ 機内でコード気にせず普段のノイキャン、快適！
*by A***ー on September 25, 2025*

快適です。機内で映画見てても全く遅延気にならないですが、電子ピアノに変換プラグ経由で接続すると多少遅延を感じます。でも機内で映画見る時は気づかないレベルで、出張多い皆さん必需品です。

### ⭐⭐⭐⭐ 程よい大きさ
*by A***ー on May 28, 2025*

簡単に接続ができ、本体も程よい大きさです。機内放送とは若干の遅延がありハウリングしますが、普通に使う分には問題を感じなかった。
