STR7-Rh2+ earphone re-cable

イヤフォンリケーブルSTR7-Rh2+は定評のある弊社オリジナルのケーブルSTR7(Spiral77構造)を採用し、 当製品で初採用となる、下記新開発のオリジナルコネクタを採用しました。 MMCXコネクタ:センターピンをロジウムメッキ処理し、金属素材・樹脂素材共に高音質設計を施した特別モデル。 2pin:ピンをロジウムメッキ処理し、金属素材・樹脂素材ともに高音質設計を施した特別モデル。 更に、採用の4.4mm、2.5mm、3.5mm端子はロジウムメッキを施した高品質なプラグを 採用しています。

その他、7層からなる遮蔽シールドを部分的に配置、振動対策、CNT(カーボンナノチューブ※1)を適切な箇所に施工することで音作りをしています。 STR7-Rh2+は前作UPG001Rh+のエッセンスを引き継ぎ、大幅に完成度を高めたモデルです。 Ref.モデルと双璧を成すBriseAudioの定番ハイグレードモデルとして開発しました。 特に相性が良い音源としては、打ち込み系、テクノ系、アニメソング系、ポップス系などで、 現代音楽に合うようキレのある音作りしております。
  Typical properties of CNTs are 20 times stronger than steel, 10 times more thermally conductive than copper, and half the density of aluminum.


STR7 (Spiral77 structure) was developed in pursuit of the ideal portable audio cable. Without sacrificing sound quality. Without sacrificing flexibility. Aiming for both, we developed this cable with the basic structure shown in the schematic diagram and our own know-how. The conductor is made of high-performance high-purity copper, in which state-of-the-art technology is applied, and 196 strands are efficiently arranged in a three-dimensional structure in order to further demonstrate its true value in portable applications.

STR7 [Spiral77) Schematic of the structure

Adopted cable slider

All processes are performed and manufactured in Japan. It also has an effect as a vibration stabilizer. Various materials are considered and adopted.


We have adopted titanium wire, which is specially treated after evaluating sound quality and selecting the material.

The tip is bent to prevent ejection & for safety measures.

Newly developed original high sound quality plug

This plug was adopted from STR7-Rh2+. All parts have been carefully examined and developed from scratch, making this plug suitable for the Rh2+ grade.

You can now also choose a dedicated terminal for SONY earphones (IER-M7 IER-M9 IER-Z1R).

High-quality rhodium-plated plug

A high-quality rhodium-plated type plug is used to match the STR7-Rh2+'s sound production.
