## Customer Reviews

### ⭐⭐⭐⭐⭐ なーぜなーぜ
*by バ***ル on October 21, 2023*

10MHz OCXOマスタークロックとDDCと併用。値段も安いし期待していなかったが音は良くなった。PCを使用する限りiDifenderとiSilencerは外せない。これを取り付けると、PCがスリープする度にDDCとの接続が切断されてしまうのが面倒だが、外す気になれないくらいの効果はある。

### ⭐⭐⭐⭐ 期待どおりでした。ホワイトノイズが激減しました。
*by A***ー on March 23, 2022*

スマホのC-TYPEメスに接続するため、C-TYPEオス-メス接続がamazonに残り後１個と表示されていたので購入に進んだのですが、別のC-TYPEオス-A-TYPEメスを選んだことに勝手に置き換わりました。希望製品が選べなかったのが残念ですが、何とか接続できて、ホワイトノイズが激減しましたので満足しています。
