Reviewed in Japan on April 29, 2025Color: whiteVerified Purchase気軽にワイヤレス化をしたかったので購入してみました。装着感、音質、機能、充電機能性能、設定などなど、価格的に考えても優秀であると思いました。不満点はなく満足してます。
ジャズとか真剣に聴きたいのであれば、数万円の商品の方が良いでしょうし、アクティブに体を動かしながらであれば、
形状が異なる物の方が良いでしょう。ワイヤレス環境で気軽に聴きたいだけなら良いと思います。

もう少し音の抜け感があると👍

Reviewed in Japan on April 24, 2025Color: BlackVerified Purchaseクセが無くフラットな音で聞きやすい。ノイズキャンセリングもかなりレベルが高く、特に低音に強い。手持ちのEAHーAZ60と比べて、アコースティック系をじっくり聴き比べると僅かに劣るが、それ以外の音源なら殆ど遜色ないくらいの高音質。バッテリーも公称値通りで誇張なし。
1万以下でこのレベルは驚き。コスパ最高とネットで騒がれているのが納得出来る、素晴らしい製品だと思います。

Reviewed in Japan on March 29, 2025Color: whiteVerified Purchaseまず良かった点から
・付け心地・・・夏季だとどうなるかわからないが、イヤーピースがサラサラした質感で数時間つけていても蒸れにくく、サイズも5段階の大きさがあり困ることはほぼないと思います。
・音質・・・PCなので環境で左右されるがドンシャリのような調整はされていないようなので、AACコーデックでも聴きやすいです。トランスミッターを使うにしても求めやすいaptX系なので満足のいくセッティングができるかと。
・稼働時間・・・他の選択肢が消えるぐらいには長時間で、実際に使ってみてとても満足しています。十年以上前のBluetoothの規格(Ver4.2)でも10時間近く持ちます。最新規格ならばカタログ通りの時間を稼働できることでしょう。
ここから私が良くないなと思ったところ。他のワイヤレスイヤホンでも言えることかもしれませんが、スマホアプリケーションからでしか切り替えられない機能があるという点です。
それは『装着検出』。これが非常に厄介に感じていて、イヤホンを外して指で持ち続けたり、机に置いたりしても一時停止と再生が暴発します。本当に切らせて下さいこれ・・・
そしてもう一点はBluetoothの接続と充電の動作です。
本製品はケースを開いたときに接続を行うのですが。ケースのバッテリー残量を確認したいときにも開ける必要があるので、イヤホン本体を充電中にも接続を始めてしまい。長く使いたい個人としてはあまり好ましくないです。
さらに満充電されたかをイヤホン本体で知ることはできないので、接続してから画面にて確認する必要があり。
「バッテリー切れまで使う→満充電→即接続→またバッテリー切れまで」という使い方をする私にとってはストレスでした。
これらの挙動はイヤホン本体を充電ケースから外したときに接続を始めればいいし、充電中はケースか本体を点灯させ、満充電で消灯するなどで工夫してほしかったです。
