​【極美品】改良版IE900 7mmX3Rユニット 標準MMCX

機材整理のため、大切にコレクションしていたイヤホンを豪華セットで出品します。
国内の著名個人ビルダー「イヤホンの道」氏より直接購入した、徹底的なこだわりが詰まった改良版DIYモデルです。さらに、「Dr.Nakamoto」氏から購入した8芯銀メッキケーブル(4.4mmバランスプラグ)をセットにしてお届けします。高域の抜けと圧倒的な解像度を引き出す、相性抜群の構成です。
本機は非常にポテンシャルが高く、イコライザー(EQ)の微調整でさらに大化けします。ご購入後、取引メッセージにて、圧倒的な奥行きと立体感を引き出すための「21バンドおすすめイコライザー調整値」をお伝えさせていただきますので、ぜひお試しください。

​高精度アルミ削り出し筐体: オリジナル同様にアルミブロックから美しく削り出されたハウジング。実物にはロゴが美しく入っています。
​7mmX3R OEMユニット: 海外OEMのポリマーブレンド素材振動板を搭載。左右を手作業で精密マッチングした妥協のない仕様です。
​標準MMCXジャック採用: 汎用性の高い標準MMCXへと改良されております。
​高品質4.4mmバランスケーブル: カーボン調の美しいプラグシェルを採用した、Dr.Nakamoto氏製の極太8芯銀メッキ線です。
​音質傾向の​圧倒的な分離感と広大な音場: ハウジングの絶妙な通気孔設計により閉塞感がなく、まるで開放型ヘッドホンで聴いているかのような「見渡せる」広い空間表現です。
​引き締まった高品質な低域: タイトで深く引き締まった低音は、多すぎず少なすぎず絶妙な量感です。
​聴き疲れしない解像度: SE846等と比べ解析力のベクトルが異なり、若干ウォーム寄りのサウンドで長時間のリスニングも快適です。

音出し確認済み。金属特有の輝きもしっかり残っており、目立つ傷のない大変美しいコンディションです。
​付属品: 8芯銀メッキケーブル(4.4mm)、専用キャリングケース、交換用イヤーピース(未開封)
​※ご注意:本商品はSENNHEISER製のIE900ではございません。優れた音響設計を参考に組み上げられたDIYカスタム品です。純粋に音質やDIYのクラフトマンシップを愛せる方にお譲りできれば幸いです。
