GRAIN

グレイン

Info

You often hear of features that exist, but have not been mastered or are not being used. Therefore, we aimed for compactness by intentionally discarding useless features.

GRAIN is a product that has been developed based on the objective of being the “smallest true wireless earbuds in the world.” The resulting earbuds are roughly the size of a woman’s pinkie, are extremely light at just 1.3g each, fit perfectly in the ears of both men and women, and are so comfortable that you may forget that you are wearing them. Additionally, the only feature available is to naturally listen to music and videos as a result of our pursuit of the smallest possible size. Because we even discarded the buttons, which normally exist, usage has been simplified to the point where they easily connect just by taking them out of their case. You cannot make phone calls, nor can you adjust the volume or skip forward, but you will never call for Siri by accident. That alone can provide relief. The appearance is also as simple as possible. Both the earbuds and the charging case are white cylinders with no adornments whatsoever. They are so light and simple that you may worry if they are actually inside. What they may lack in appearance, they make up for with the reliability and high functionality inside.

  • Independently developed a speaker with a diameter of 4mm for minimization.
  • Comes with a small rechargeable battery that is made in Japan, ensuring safety and peace of mind.
  • An ultra-dense circuit board is installed for minimization.
  • The latest LDS antenna is installed to achieve a stable signal that is resistant to interruptions.
  • Equipped with Bluetooth® Qualcomm QCC3026. Compared to existing models, it has improved power-saving abilities, lower latency, better audio quality, and a more stable signal. The design, development, and mass production are all carried out in Japan.

    There is no need for this and that. Many things have been removed for ease of use while keeping it powerful. GRAIN is a pair of one-of-a-kind complete wireless earphones made real with such intentions.

 

機能があっても

「使いこなせない」「使っていない」

よく聞く話である。

だから無駄な機能は敢えて捨てて、小さくしよう。


GRAINは「世界一小さな完全ワイヤレスイヤホン」を目標に開発したプロダクトである。

完成したイヤホンの大きさは女性の小指程度で片耳1.3gと極めて軽く、男女問わず耳にすっぽりとおさまり、つけていることを忘れるほど違和感がないものに仕上がった。

また、極限まで小ささに拘ったことで、逆に音楽や動画を視聴する以外の機能を排除した。本来あるはずのボタンまで捨てたことでケースから取り出すだけで簡単に接続できるシンプルな使い方になった。通話はできないし、音量調整も、早送りもできないが、操作を間違えてSiriを呼び出すことは完全になくなった。それだけでほっとする。

プロダクトの装いも極めてシンプル。
イヤホンも充電ケースも、加飾を一切施していないただの白い円筒型。

軽いし、ほんとうに中身が入っているのか心配になるシンプルさ。
しかし、装いとは裏腹に中には安心と高機能が詰まっている。

  • 最小化のために直径4mmスピーカーを独自開発。
  • 安全・安心国産の小型充電池を搭載。
  • 基板は超高密度実装を施し7.5mmまで小型化。
  • aptXコーデックに対応し、遅延なく高音質で再生が可能。
  • 筐体の内側全周囲にLDSアンテナを搭載し、途切れにくく安定した通信を実現。
  • Bluetooth® Qualcomm QCC3026を搭載。従来と比べ省電力、低遅延、高音質、安定通信が向上。
  • デザイン、開発、設計、量産を全て日本で実施。

    あれもこれも必要ない。
    いろんなものを排除し、わかりやすい、なのにハイスペック。
    GRAINはそんな想いを込めて具現化した唯一無二の完全ワイヤレスイヤホンとなった。
