I don't normally write reviews, but I didn't see any for this product and took a chance on buying it, and it worked out well, so I thought I should write one.

I have an iPhone that I use to play music via the aux-in port in my Prius and there was a lot of noise in the signal, especially if the headlights were on, and this was particularly problematic if I turned the volume way up for soft music (e.g. Renaissance lute music).

With this noise filter, that problem is gone.

I have a car stereo with an AUX-in port. Unfortunately, when my car is running and I have my iPod plugged in, I get a very obnoxious electronic whine (more noticeable during the summer at night, with the headlights on and the ac running...the more electrics running in your car, the louder the whine). It would get so bad that it would make listening to music more of an annoyance than anything.

Searching on Amazon for an auxiliary charger for my iTouch, I came across this in a "Buy these two devices together and save" item. And I am happy to say it completely eliminated all electronic whine/feedback. It could not be simpler to install...plug one end of the isolator into your AUX port, and the other end into your iPod/mp3 player/auxiliary accessory(Griffin AutoPilot FM Transmitter for iPod, Kensington LiquidAUX Auxiliary Car Kit with Remote for iPod; iPhone 1G, 3G, etc.) It works like a charm. The way it works is its circuitry isolates any ground loops in your stereo (depending upon how it was installed, you may have a bad ground and that can cause an annoying whine).

HIGHLY recommended for anyone who wants to listen to their music and charge at the same time.

Completely eliminated the ground noise I was getting from the Belkin Bluetooth receiver I bought to get music and hand free calls over my car stereo.

I have two cars that with AUX inputs that I'm using with a Griffen AutoPilot to power my iPod and connect to the AUX input. The AutoPilot makes a high pitched sound that cycles on and off in both of my cars. I also was getting a lot of alternator whine in one of my cars. I was a bit skeptical of the PAC SNI-1/3.5, but I figured with it's low price, I'd buy one and try it out. The device cured both of the noise issues I was experiencing without compromising sound quality. The device works so well that I ordered a second one for my wife's car.

I had a ignition/alternator whine in my Sirius radio that was most noticeable when the volume was turned up. This noise fluctuated depending on the revs. of the engine. I plugged this filter in line and the noise is GONE!! No noticeable loss in volume or sound quality either. If you've got your satellite radio, iPod, MP3 player, or similar audio equipment plugged into your car stereo with a patch cable and you're getting noise like I described above, try this filter!!!

So cheap group loop isolators are fairly notorious for killing your bass, but I'd had PAC recommended as a low cost solution without the drawbacks. Not so - fitting this between my smartphone and car aux port filtered out all the low frequencies making audio (even speech) sound like it was coming from a 5 dollar pair of earplugs. Terrible - I'll put up with the power interference until I can find a better GLI manufacturer.

I have an old Dell PC in my living room that I'm using as a DVR. I had a line out from the sound card to an Onkyo receiver hooked up to the TV. Unfortunately, there was an annoying hum. I plugged this in between the sound card and the receiver and the hum went away. Simple as that.

Pros: Isolated and removed noise it was intended to remove.
Cons: Lowered and distorted volume to a degree that it was unusable.

I have a 2010 Honda Element, which has a 3.5mm aux port. Before this product, whenever I would plug the cord into my phone for music, if music wasn't playing, it would pop and crackle very loud.

I installed this product in between. It did eliminate the pop and crackle, but I was amazed at how much it lowered the volume of the music. I had to turn the stereo almost all the way up, as well as my phone just for it to be somewhat audible. Either the isolator or simply the fact that it was turned up so "loud," created an incredible amount of distortion.

I would have loved for this to work, but it just doesn't with my set up.
