Review: 3年ほど使っていた安物イヤホン(3000円)がついに壊れモノラルになったのでこちらに買い替え。 箱やケースから圧倒的に価格感が違うので感動しました。 低音も高音も不満がなく、アプリにて気軽に音質を触れるので曲に合わせてイコライザーを変えて楽しんでいます。 フィット感は個人差があるようですが…同封されているフィッティングパーツで自分は問題なかったです。 ノイキャン機能は特に必要ないので個人的にはこれで十分に満足できています。
Review: 立て続けにワイヤレスイヤホンが壊れるので安いヤツにしようと思い、グレードダウンしました。 音はまあ及第点ですが、やはりノイズキャンセリング、外音取り込み機能がないのは痛い…
