For flat sound faithful to the original sound of the ER4SR, the ER4XR emphasizes low frequency with high resolution and produces powerful and dynamic sound that you won't think of a balanced armature type. The mid-high range is not buried at low ranges, allowing you to play crisp music with your flagship.

Review: さすがの遮音性と再現性 - 接続部が独特なのでリケーブルは専用品が必要です
Review: Made in USAが欲しくて中古で買いました。 - 値段は以前の定価くらいでしたが、Made in USAのもの(パッケージが赤基調)が欲しくてあえて中古で買いました。 ヘッドホンはHifiman ANANDAで以下の構成でレコードのDSD5.6MHz録音を聴いています。 環境設定をする時に夜使う時に動作確認用に購入しました。 Rock5b→FX-AUDIO-PGN2→iFi hip dac2→TOPPING A30 Pro イヤホンはIE800しか持っておらず、感度とインピーダンスがANANDAに近くなる本製品を選びました。 TOPPING A30 ProはデジタルボリュームなのでMAX0dBで使うことができるのがポイントです。 想定通りANANDAと同じボリューム設定で聴けています。 最初、高音側があまり出ていないので失敗したかなと思いましたが、フィルターを交換したら綺麗な高音が出ました!
