  • Killing my buzz
Number of Items: 1
Tried two other similar products to eliminate buzz in my home theater subwoofer and neither worked at all. I have a long RCA running through the wall and ceiling from the amp to subwoofer that was already installed when I moved in. Doesn’t appear to be a shielded cable. Even the slightest increase on the subwoofer volume dial would produce a loud buzz basically making the subwoofer useless. This isolator made an enormous difference. Still a very slight buzz when I turn the volume up high, but at reasonable volume levels no noise at all. I can now use the subwoofer with pretty much no noticeable interference. Because this item has 3.5 mm input and output I had to use RCA adapters and the setup worked perfectly. Definitely recommend trying this product if you’re having a similar home audio problem. ... show more

  • Simple and immediate solution to unwanted noise!
Number of Items: 2
I bought two of these. I had two different sound issues and they were both resolved by this ground loop noise isolator. One was used with a work laptop. The 1/8" audio cable from the laptop to my mixer was the first place I used it. It immediately resolved my issues. The 2nd isolator was plugged into my gaming pc that runs into a mixer. It had low level static. This fixed the issue completely. Highly recommended! ... show more

Just received. It removed the majority of the static, not all, but most. Also, it made my speakers a bit louder and increased bass in which I appreciate. Overall, I’m satisfied.

  • Reduced the Noise, but Didn’t Completely Eliminate It
Number of Items: 1
I bought this to deal with an annoying humming/whining noise coming through a 3.5mm audio connection. Installation couldn’t be much easier—just connect it inline between the audio source and the stereo. It made an immediate difference and reduced most of the background noise. However, in my setup I could still hear a faint amount of interference when the volume was turned up with nothing playing. I also noticed a slight change in the sound compared with connecting the cable directly, although it wasn’t significant enough to bother me during normal listening. For such a small and inexpensive device, it did a good job solving most of the problem without requiring any changes to the wiring. Just don’t expect it to magically fix every type of audio interference. Useful little adapter and worth keeping around, but because it didn’t completely eliminate the noise in my setup, I’m giving it 4 stars. ... show more

  • Reduced Hiss on Cardo Spirit Communicator
Number of Items: 1
Bought to use with a Cardo Spirit communicator with Shure 215 IEMs. There is a very noticeable hiss when the communicator is actively transmitting audio that is likely negligible with the included speakers, but is evident with greater sound isolation and quality. This noise isolator greatly reduced the hiss, to be effectively inaudible when audio is playing. Would recommend for similar use cases. Great price, but a little bulky on a helmet for motorsports/atv/etc. ... show more

  • All inference was gone!
Number of Items: 1
Bought an aftermarket carplay unit which could only be used with an auxiliary cable rather than bluetooth. There was interference with the pandora playing out the speakers. Both this noise isolator and it makes a huge difference. No more interference and the sound from the speakers is now great!

  • Replacment for razer audio mixer pc

It worked to remove the buzing like sounds i would hear on my nova pros when i plugged in my razer audio mixer to my nova pro dac. Idk if it's how im now running my audio but seem like a very slight drop in over all audio loudness just enough if so for it to be questionable but like I said I am also running my audio differently to use the device regardless if it is or isn't its a 5 star for me ... show more

It took almost all the hiss out of my signal chain. Unless you are recording with it, most people will find this suitable. Easy connection. Versatile, I used it before the aux in on my mixer, and the phones out.
