## Customer Reviews

### ⭐⭐⭐⭐⭐ ゼンハイザーは最高！
*by 玉***ぎ on April 29, 2025*

SNOYノイキャンから買い替え！ゼンハイザーは最高！SONYの３倍は最高！音の解像度がよく、軽いし、耳からも落ちない。そもそも運動中には使わないので、防水性はわからない。少なく見積もっても最高！！！！

### ⭐⭐⭐⭐⭐ 思った以上
*by ®***️ on November 30, 2024*

ジョギング用に購入しました。耳に合っていないのか、走っている時たまに落ちます。ゼンハイザーデビューですが、イコライザーで好きにカスタムできるし、低音パワフルなのにドンシャリも気にならず、とてもクリアな音質。この価格帯でこの音質は大満足。ジョギング以外にも電車利用時にも使ってます。

### ⭐⭐⭐⭐ 自然な音色が耳当たり良い
*by M***E on February 17, 2025*

以前からゼンハイザーの自然な音色に魅了されていました。この製品も音色の再現が素晴らしくお薦めです。
