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.

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.

Excellent perfomance: no more Alternator Squeal

The price is right and if you need a stereo-mini ground loop isolator, look no further. My Aux-in was very noisy until I used this filter. Just plug it in right before the Aux-in.

Works perfectly

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.

Problem Solved!

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.

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!

Essential little piece of equipment

I've been doing audio demonstrations with some pretty unstable power outlets and the SNI-1/3.5 has become a required filter in my audio chain. Whether connecting up my laptop or an iPod, it pretty much eliminates all the nasty buzzing noise on the line. It's not super cheap but I have yet to find another ultra-portable filter that works as well. I ended up buying two.

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.

Works great!

I was having an issue playing music over my car stereo through my smartphone's audio out while charging, and someone recommended I get a ground loop isolator to solve the problem. I did some hunting around, but most solutions I found were for home stereos, and I didn't want to mess around with adapters.

This unit was exactly what I needed, and at the right price. It's small enough that it's not too obtrusive in a car, and more importantly, it works really well. I'd definitely recommend this to others.

WORKS!

After doing research on how to eliminate the ground loop hum/buzz I was getting on my SoundWorks amplified 2.1 speaker system connected to an Iogear Miniview DVI 4-Port USB KVM Switch I decided to give this product a try. I checked online and found that it was available for an excellent price at Sonix Electronix. I ordered four of them, one for each computer connection. Installing them on each of the audio outputs of the KVM completely resolved the problem - NO MORE HUM/BUZZ! I highly recommend this product and have done so already to Iogear's technical support.

Not the prettiest little device, but definitely does the job it was purchased for. Super simple install (inline to the AUX jack) and instant results. For reference, this is being used on a 2009 Mazda 3 with the infamous whine induced by having a device (phone in this instance) plugged into AUX audio port and charging from a 12v car charger at the same time. The PAC SNI-1/3.5 has been in place for about a year now and still works like a champ. This is a must-have to eliminate alternator whine.

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.

Yes, it works!

I don't have an iPod, but I have a crackberry with an 8 GB memory chip. I like to listen to my music, and the stereo's aux port works just fine - but whenever I tried to recharge at the same time with the car charger, omg - the hum was unbearable. This little puppy did the trick. Sits behind the dash, never think about it. Awesome. (hope I remember to take it with me whenever I sell this car!)

This unit works exactly as advertised. I replaced my factory installed radio because I wanted to get away from the low-fi FM modulator I was using to listen to my satellite radio, but the ignition noise was making me crazy. Then I found this gem! I saw the reviews and I must say, they were right on the money -- this thing eliminated the ignition noise with absolutely no negative impact on the audio quality that I could detect. It's worth every penny!

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!

Works excellent.

Just as many have said about this type of product ... works very well to cancel out "noise" (hiss) when connecting your satellite radio receiver to your head unit aux input. some have mentioned that these tend to filter out a lot of the highs and lows, but when you are listening to satellite broadcasts, the fidelity of the audio is somewhat muted anyway.

i give this unit a thumbs up for the removal of the hiss, for the quality of the filtered audio, and for the benefit of having to only use your existing audio patch cable. many other units are RCA-type female connectors. they would require larger and more cables to complete your setup.

even if you do not think this would improve your audio, or if you think that your xm/sirius sound is okay, get one of these and realize better sound with your system.

I bought this filter for hooking up my smartphone to my aux input in my car's stereo system.

Cheap & Easy Fix for Poorly Designed Car!

This was very easy to install to cure the problems associated with Ground Loop problems in modern cars. I own a 2008 Prius that has a 3.5mm jack built into the car designed specifically to connect your portable MP3 player to the factory car sound system. It works great until you connect your portable device to 12V car power and then that awful squeal with the audio.

I just plugged the PAC SNIj-1/3.5 into the cars audio port and added a separately purchased adapter/extension cable to the device to my MP3 player and problem solved! NO TOOLS REQUIRED!

Be advised that this device along with any other one you buy will lower the input voltage of the audio slightly which will lower the volume a bit, but it does eliminate the issue 100%. Just make sure you purchase an extension cable with the right gender at the ends so you can hide the PAC in your console or under a seat etc. and it will be out of the way.

Enjoy!
