If you are like most folks, you probably hate when you plug your portable music player into the 3.5mm (headphone jack) aux input on your car stereo and get an annoying whine that interferes with music playback. Well if so, the PAC SNI-1/3.5 is the answer for you. PAC's SNI-1/3.5 preamp noise filter plugs in between your receiver's auxiliary input and your portable music player and helps reduce noise caused by ground loops. The filter includes a female 3.5mm input, a male 3.5mm output, and 10 inches of cable for each jack.

Good value but
This is the third SNI-1/3.5 I've bought, and they seem to work great for the first year or so and then the audio quality begins to get muffled and I have to buy another. I should note that I use this unit for my music input in a small (noisy) airplane, and there's lots of vibration the unit needs to deal with. So that said, it's seems to be a good unit but wouldn't recommend it in a high vibration environment.

eliminates static in car
I got this gadget to eliminate the bad static I heard when listening to my DroidX through the car speakers and plugged in to the car charger at the same time. Works like a charm! A friend had recommended it and it works great for him too on his iPhone.

Worked magically. A MUST have item.
I almost gave up on the noise coming from the audio jack of my Droid X when it's hooked to the power supply from my car. Then I found this product and it worked beautifully. Now I play music using Droid X while I'm driving without any problem. I finally succeeded in replacing my old iPod with my Android phone.

Recently bought a Mazda5 with an AUX jack. Problem was, when I plugged my iPod into it, it sounded like the noise was coming through a lawn mower. After some searching, I came across this little gem. Plugged it in between the headphone jack of my iPod and the AUX jack of my Mazda and voila, no more lawn mower noise, just sweet, sweet music. Thanks Sonic!
My one complaint - seems like this probably could have been a bit more sleek. It hides well enough (it's about a 2" cube) but something a bit slimmer would have been even better. That's just a minor quibble though.

This device eliminated the interference I experienced when I had my iPhone connected to the car's power source and sound system. It fits nicely in the console box of my 2007 Prius and plugs into the port for auxiliary devices. I plug the audio cable directly into the device. Simple. Inexpensive. Effective.

Handled non-standard use perfectly
I grabbed two of these to correct an issue with a custom audio network between two computers, an office phone, a cell phone, and one headset with microphone.
Understandably, this generated a lot of hum, hiss, and clicking on its own, especially when the cell was plugged into the computer to charge...
With both phone outputs run through these, there is not a single click or hum left in the sound, and the stereo separation has actually improved.
In short, these have done the seemingly impossible - highly recommended!

The cure for satellite radio hum
My VW has an audio input which I use for my Siruis s50 sat. radio. Before using this device any acceleration / deceleration would register through my loudspeakers. With this device in between the radio and the sat device all hum was removed, however this device appears to be failing only after 6 months use.

Works as advertised
I bought this for my Toyota Camry with an auxiliary input. With some cars, if you try to plug in the power as well as the audio cable to your iPod/media player, there will be electronic interference and cause a slight buzzing through the speakers. By putting this adapter in between the player and the input for your car, this can reduce (and for me, remove) any of that interference.
Great product, highly recommended!

I had a slight buzzing noise coming from my TV after I hooked up computer speakers to it. I tried everything, then bought this. Still didn't work. Buzz is low enough that I can live with... I am rating this item ONE star only b/c it didnt fix what I bought it for. Maybe I bought the wrong item or attempted the correct a problem that isnt suppose to be fxed by this kind of product. I dont know.
