## Overview

The iFi iDefender+ USB Audio Ground Loop Eliminator is a compact, metallic device designed to reduce unwanted ground loop noise in USB audio setups. Compatible with USB Type A connections, it preserves USB 3.0 high-speed data transfer while disconnecting USB power grounds to minimize interference.

While it significantly lowers noise floors, it may not completely eliminate all ground loop noise in every environment.

## Description

desertcart.com: iFi iDefender+ USB Audio Ground Loop Eliminator (Type A > A) : Electronics

Review: Helped with white noise problem - Made a noticeable difference in the sound quality. I had been dealing with a heavy noise floor for a long time. Tried all the tips for solving ground loop issues and nothing worked. In my case it was what sounded like loud radio static on a dead station. I thought maybe I had a bad SM7B or interface and it was very frustrating. The mic and audio was always unusable due to a super heavy amount of white noise, more than you'd expect from a typical noise floor. This appears to have drastically lowered the noise. It isn't 100% but the audio is absolutely usable now compared to the hot trash I was dealing with prior. It's expensive for what feels like a fancy flash drive, but it was worth it in my case. The noise issue must've been something interfering from inside my PC, if you've done enough troubleshooting with ground loop noise and still have static and think it is your computer that might be the culprit, then this will likely help with your issue too. I also coupled this with a cable that had ferrite as well to further help with reduction.
Review: Doesn't work well at all - I have attached 3 photos showing the line noise from a uac222. One with no usb ground eliminator and the other with the eliminator powered and not powered. Doesn't work well at all. I would have no problem if this was a ground noise reducer bevause then the product you are being sold would be accurate. This does NOT eliminate ground noise. It may reduce audible ground noise to a more acceptable level. Hoever this porduct by no means will elikinate ground loops. The frequencies if searched for can be easily found in a spectrum plotter tool. I have reported this losting to desertcart as being inacurate. If you need to redice ground noise: then this is a good product for you. If you are looking to eliminate it as the product clearly states it will. This will simply not do that. And marketing the product as so is a somewhat dishonest dipictiin of yhis products capabilities. Please see attached images for reference and proof of function.
