なーぜなーぜ
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。

好みの問題ではある
たぶんノイズ対策の効果はあると思いますが、良くいえば柔らかい音、悪くいえば少しこもった音になります。

期待どおりでした。ホワイトノイズが激減しました。
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。

Its works great for USB ground loop
It works, I had a ground loop issue on my USB ports via my MB, and now its silent, Little to no noise coming from my monitors, The only noise is just some hiss from my monitors themselves. This adaptor will only work if your USB port has any group loop issues. Best way to find out is plug your audio interface/Speakers/Headphones in a different laptop with the power plugged in, If you still hear buzz with you or device and if you cant hear anything you have ground loop may be via your USB port. If you hear any noise through your audio interface/Speakers/Headphones, You have a power ground loop problem, If your audio interface/Speakers/Headphones don't make any noise with the power plugged in your laptop you have ground loop on your USBs and this product should fix it Finally, make sure to use the 5v input on the adaptor or it will not work, You don't need to buy the external PSU from the company, Just use a USB charger and make sure its 5v dc @ 2A.

Money wasted! :(
Should remove the computer rumble from speakers, but doesn’t work as promised. Tested with several setups, cables and power outlets scenarios. Sadly 60 euro’s wasted:(

Maravilloso!!
Después de actualizar mi equipo con nuevos altavoces e interface de audio empezó un ruido horrible que cuando usaba según qué apps era ensordecedor. Después de mucho research acabé comprando este aparato sin demasiadas expectativas y es magia. Todo ruido infernal ha desaparecido!! Es hasta raro escuchar el silencio que hay cuando simplemente no hago nada en el ordenador. Eso sí, con un alimentador de 5v, si no... En mi caso no funciona, pero una vez alimentada la llave... Es mágico? Por pega podría decir que me hubiera gustado la versión usb a en ambos lados... Pero nada que un adaptador no pueda solucionar.
