iFi Audio iSilencer Plus USB C to C Electrical Noise Conditioner

After installing on our system the buzz went away

Will smooth out usb audio. Dont expect pure magic though.

Unfortunately in my case I did not have "moderate" GPU noise. My RTX 4070ti polutes the 5V rail for USB insanely. I couldn't NOT review this product however. It cut down the worst squealing and chopping sounds I have ever heard to a bare minimum. It's very obvious my scenario is pushing this thing to it's absolute limit and it's putting up a damn good fight. My recommendation for intense GPU noise would be the iFi Audio Defender+ but don't count this thing out. It dropped noise nearly ten fold in the wrong application. I can only image what it does in the correct application.

This isn’t galvanic isolation so it won’t block all noise but it will increase bass quantity by about 10 - 15% depending on setup and headphone type.Mids and treble are cleaner because of less HF noise getting through the digital power so if you have silver cables in your system this will especially make it sound smoother because 4 - 6khz is elevated when treble is introduced due to the material properties.

If you use PC you must have a device like this. Cleans up the audio signal immediately.
