Review: 音質の違いはわかりませんでしたが、耳から絶対落ちないなと確信を持てるぐらい密着感があります。 ここの評価は人によりけりかと思います。密着感が強くて安心ですが、逆を言えばイヤホンが耳についていると主張してくるわけで、付けてるのを忘れるようなつけ心地を求めている人には合わないです。
Review: 遮音性とフィット感がいいですね、デメリットは透明なので少し耳垢が目立ちやすいです。

QC ULTRAで使用しています。 純正の装着感がイマイチ頼りないので変えてみました。 まず装着感が向上します。純正は外れやすい傾向がありますが、本商品はサイズさえ合わせられれば、非常に安定します。外れやすさは全く感じませんでした。 QC ULTRAは、BOSEらしい低域の出るイヤホンだと思いますが、本商品に換えることで密閉がしっかり取れるので、低域がさらに増強されます。 曲によっては若干ブーミーになるので、気になる人はEQで調整した方が良いかもです。 密閉が上がるのでノイキャンもさらに増強され、航空機内や地下鉄などのシビアコンディションでは、もはやAirPodsPro2などでは全く相手にならない、異次元のノイキャンが体験できます。 外す時には耳穴に貼り付く感じを若干受けますが、装着中は気になりません。 結構なお値段ですが、導入メリットは価格に見合ったものだと思います。特に、高いノイキャン性能を求める人におすすめします。
