iFi audio iDefender+ Reviews
WOW!! This Thing Works!
I am using a RODE Podcaster running through my Fender Passport and I have my desktop plugged in. I had a constant low buzz in my speakers, and it was worse when I used my mouse. I tried everything from grounding to balanced cables and nothing worked. I finally resorted to YouTube for help, and someone suggested the iDefender. I ordered it last week and it showed up this morning. When I first plugged it in, the low buzz went away, but now I had a high-pitched whine....that was not good and even actually worse than the buzz. I then decided to just plug it into a power supply with a USBC and low and behold, all the noise went away! I am a happy man. Thanks for a great product!
Works as advertised!
I recently upgraded from PreSonus Eris E3.5 speakers to some KRK Classic 5's to use with my Audient EVO 4 interface and noticed some annoying static after the upgrade. I'm using EWI balanced TRS cables from Audiopile, which have always been high-quality and reliable for me, so that wasn't the issue. After some Googling, this is apparently a common issue with USB interfaces. Long story short, finally pulled the trigger on the iDefender+ and am glad I did. Even though having to buy yet another piece to the setup is a bummer, it did exactly what it claims. Since my USB ports are a bit cramped, I got a braided right-angle USB-C cable from Amazon and the fitment is great. That paired with an iPhone power adapter works perfectly. If you have static/noise with a USB interface, this is exactly what you need.
Being the skeptic that I am, I was gobsmacked at how well this removed all of the noise in my speakers. Actually, it didn't at first and I thought it was just another bit of snake oil, but then I plugged in the external power on the side and POOF, no more hissing or crackling. Couldn't be happier!
Fixed motherboard noise on my Scarlett Solo
I had a lot of background noise on my microphone and mechanical noises that would play through my speakers. After buying this (and using a type C phone charger to re-power it), all of my problems went away. I have clear microphone quality as well as speaker quality. The background humming and unusual noises have come to an end.
finally able to stop the buzz!
My monitors are hooked up to my laptop via a docking station and a Firefly DAC. A while back they started buzzing pretty bad - couldn't figure out what changed. I tried everything, then just stopped using the monitors and didn't know what to do. Did some research and found this device, and it did the trick and solved the buzzing!
This is supposed to isolate the ground loops. I am an electrical engineer, I know what I am talking about. Didn't do it. The proof is the USB device connected got power through it! Obviously the noise I was trying to prevent in the audio didn't change. The only reason I am not returning it for a refund is, it is not that much money. Maybe the unit I received was defective. Good luck.
