When it came to improving how earphones felt when worn, it was common to create an organic shape, but there were also times when this actually didn’t work out owing to there being an infinite variety of ear shapes. Having gone right back to the start and rethinking earphones and how they fit, we realized that it was possible to achieve a good fit for a great variety of ear shapes by holding the earphones to the ear at one point. The geometrical shape arrived at as a result of this realization doesn’t look like it would fit well based on conventional common sense; the fit, however, actually feels as though the shape of the product has been customized to the shape of the user’s ears. The metal housing, which produces high sound quality, is weighty, but you do not feel this weight owing to the good fit of the product. You can customize these earphones by replacing the inner filter yourself to find a sound quality that suits you; in doing so, you can gain a variety of “optimums”.

装着感をよくするためには有機的な形態にすることが一般的でしたが、実際は千差万別の耳の形にはそれが当てはまらない場合もありました。 装着感をゼロから考え直した結果、イヤホンをポイントで耳に当てることがより多くの耳の形に有効な装着感を得られることがわかりました。 その結果できた幾何形態の形は今までの常識では装着感が良さそうには見えませんが、実際はまるで耳の形に合わせてカスタマイズしたかのような装着感です。 音質の良い金属筐体は重さがありますが、装着感の良さから重さも感じることはありません。 内部のフィルターを自分で付け替えられて音質を好みに合わせてカスタマイズすることができるこのイヤホンは、様々な「最適」が得られます。
