Review: Good daily for daily use - Very comfortable to wear. Much better comfort than inear type earbuds Bass sounds quite punchy for an open ear type. Unfortunately right side broke after a month but Tozo support was quick to send me a replacement.
Review: These are great! Such a great buy. - I ordered these last week and they arrived fast enough for me to be able to use them as soon as I can. Audio quality from the open buds are very nice. May it be from music, down to calls. Perfect. Painful? Nope. They are very much comfortable to wear on the ears. Even if you use them for a long time. I bought these most especially for calls. The mic is great. A week of calls made using these open buds, and there has been no complaints about how unclear my voice is (which happens a lot when I use most of my old earphones). Which means the mic works very fine. And they surely make me happy. These work well too, even with some bit of distance between me and my device. And lastly, they are very comfy when you are the type of person who likes to move around much while having something to listen to a lot. I run and use these at the gym and they are amazing. Definitely worth the buy! Worth recommending. Thanks.

### ⭐⭐⭐⭐⭐ These are great! Such a great buy.

### ⭐⭐⭐⭐ ナチュラルではないが楽しい音で使い勝手もいい
*by R***C on August 8, 2024*

海外勢の評価が高かったので購入してみました。マルチポイント対応で切り替えも早く、またアプリで各種操作を自由に設定できる等使い勝手が非常にいいです。音は良くも悪くも派手めな音作りがされていて、決してナチュラルな音ではない（特に低域）のですが、屋外であっても音楽聴いてて楽しめる感じにうまくチューニングされてると感じます。2軸可動なフック構造のおかげでフィット感やユニット位置を微調整でき、音量も得られやすいので、運動時のBGM使い等自然な鳴りより迫力や楽しさを求める向きにおすすめです いい点 使い勝手のよさ 2軸調整の機構はかなり有用と感じる 音量も大きく元気で量感のある低域（好みはありますが） マルチポイント対応 イマイチな点 中低域あたりがややマディ 実はあまり伸びてない低音 わりと無骨なデザイン フィット感 二軸で調整できる機構のおかげでキツめにもユルめにもできますし、ユニットの位置も微調整できます。オープンイヤー型は外耳孔とユニットの位置関係で大きく音が変わってしまうので、これがベストな場所に調整できるのはとても有用だと感じました。ある意味アコースティックなEQとしても使えるので面白いです。 使い勝手 マルチポイント対応なので複数のスマホとタブレット等に同時接続できます。切り替えもかなり早い。また、各種操作は専用アプリで設定でき、シングル/ダブル/トリプル/長押しを左右それぞれ（計8操作）割り当て可能です。 前述のフィット調整も含め、できることは全部カスタム可能にしてみました感があって使い勝手はかなりいいです。 音質・音色 音質とはちょっと違いますが、オープンイヤー型としては最大音量がかなり大きいと感じます。ユニット位置を細かく調整できるのでそう感じるのかもしれません。 音色は基本的にはドンシャリ傾向。高域は刺さるような感じはなく中低域が元気に鳴ります。ただボリューム60 -70%あたりから低域はあまり変わらず中〜高域を中心にゲインが上がるようで、最大音量に近づくにつれフラット気味になっていきます。とはいえ前述の通り最大音量が大きいので、個人的にはそこまで音量上げて使うことはないかな。 音質的には中〜中低域がちょっとマディ。ちょっと疑問を感じたので低域にsine波送って確認してみたんですが、下は意外と伸びてないです。具体的には70Hzあたりから倍音が乗り始め、50Hz以下になると倍音中心で基音はほぼ聞こえなくなります。このsub-bassの倍音が中低域の曇りに繋がってるんだと思います。本機について海外のレビューで「低音がしっかり出てる」というのをよく見かけますが見通しはあまりよくないのでご注意を。 ということで、ナチュラルな音を求める人にはあまり向きません。また中低域が強調されますので動画視聴では人の声等にちょっと違和感を覚えます（逆にSEの迫力なんかは出やすいです） とはいえ元気で楽しい味付けですし、そもそも「ながら聴き」のためのオープンイヤーなので使っててそこまで気になるようなものではないです。屋外で環境音も聴きたい時や、周囲に人がいる状況で使う時などはむしろこの味付けのおかげで小音量でも楽しく聴けます。イメージ的にはドンシャリ傾向で低音が元気なBluetoothスピーカーって感じかな。カナル型でこの感じだとちょっと微妙だけどオープンイヤーなら全然アリだと思いました。 マルチポイント対応で使い勝手もよく、フィットも微調整が可能で聴いてて楽しい音、かつ価格も控えめ……ということでオープンイヤー型の中では良い機種だと思います。音量も取れますが小音量でこそ威力を発揮する感じの味付けで、ワークアウトやキッチンなんかでも使いやすく女性にもお勧め。見た目がちょっと無骨なのがちょっと惜しいかな。
