Earphone Re-Cable NAOBI-LE

NAOBI-LE earphone re-cable adopts the original wire material "NAOBI", which was newly developed to pursue ease of use in various applications such as commuting to work and school, and to ensure the maximum sound quality. The new wire material "NAOBI" will be released for the first time in the earphone cable NAOBI-LE.

イヤフォン側コネクタには弊社オリジナル開発のパーツ含め、弊社基準をパスしたもののみを使用。 プラグにはYATONO-LE.で初採用の、弊社オリジナル高品質L字プラグ(4.4mm、2.5mm、3.5mm)を採用しました。 弊社ケーブルの特徴である様々な素材を組み合わせた高音質施工も施し音質調整がされています。 ブリスオーディオらしい音は残しつつ十分な密度感があり、繊細で細かな音の再現性は線材ラインナップ中最高レベルのポテンシャルを秘めます。

NAOBI線材はSTR7と同じSpiral77構造を採用。ただし、最小構成単位の素線はさらに細い線を使用しています。 組み合わされる4.4㎜、2.5㎜、3.5㎜プラグはLEグレード専用のオリジナルL型端子で目指す音質を考慮し素材から見直し開発しています。 素材メーカー&国立の研究機関と共同開発のオーディオ用にチューニングを施したCNT(カーボンナノチューブ)を採用。 2ピン、MMCX、A2DC端子なども音質を考慮しオリジナル端子などを採用。


Typical properties of CNTs include
20 times stronger than steel, 10 times more thermally conductive than copper, and half the density of aluminum.    
Excellent shielding ability. Various other useful physical properties.   
(The properties of CNTs vary depending on single-phase or multilayer structure, etc.)
