Product Description

Amazon.com

Have you tried using a phone connecting cable in your car for your MP3 player or SmartPhone and been bothered by a "hum" that accompanies the sound?  The best way to avoid that bothersome humming is to connect directly into your car's AUX port so you get pure sound without interference from the car's electrical system.  The Kensington Noise Reducing Car Audio AUX Cable lets you do that easily and efficiently.

The direct AUX connection and noise reducing technology of the Kensington AUX Audio Cable combine to deliver clear, clean sound through your car's stereo.  The 4 foot long, 3.5mm audio cable is braided for long term durability and to keep it from tangling.  The cable plugs into your car's AUX port and into the headphone jack of your portable device.  And you're in business.  The only humming you'll hear will be your own!

Note: Your car must be equipped with an auxiliary port (most newer models are) and your device must come with a 3.5 mm headset jack.

  • Provides a direct connection to your car's AUX (auxiliary) port for pure sound

My 2007 Toyota Camry Hybrid had terrible problem with ground loop noise. It was unbearable that when I play music through the Aux jack while having the charger plugged in (any devices). There were "weeeezing" noises that drowned the music. I had to unplug my devices from the charger if I wanted to listen to clear music. This Kensington Noise Reducing device works wonder. 100% of the noise was gone. I hear no trace of ground loop noise playing music while charging my devices! The length of the cable is plenty for me. Well worth the money!

Does what it claims, if you hear hissing or feedback when running your iPod (or, I presume, any other audio device) through your aux jack this should clear it up. In my case I use a Kensington LiquidAux running into a cassette adapter (my car predates aux jacks). I listen mainly to audiobooks and had an issue with clipping and distortion of the spoken high frequencies. Once I installed this between the cassette adapter and the LiquidAux, the problem disappeared. I also like the braided cord better than the usual plastic/vinyl cord you see, it feels sturdier.

The only thing I would change is the length of the cord. I chose this device over the competing product by Griffin because the cord was 2' shorter - and even the 4' cord of this device is overkill for my setup. I have about 3' of extra cord coiled up inside my console. Of course depending on your situation maybe you need the extra cord, but I didn't. The other thing to remember is that you will likely need at least one 1/8" adapter (I needed 2, because of the cassette adapter) in order to plug this device into a LiquidAux or similar system. If you don't buy the adapters here, try Radio Shack.

I purchased this product in August because I got sick of the humming from my stereo when I was charging my iPhone 4. This cord ABSOLUTELY eliminated ANY and ALL noise created by my car stereo. BUT, the plug had been coming loose from the cord on the smaller end of the cord for the last week or two, but I hadn't much noticed it. Well, the cord stopped working yesterday. Overall, I really wish I had kept shopping for a different product because this product just isn't very durable.

UPDATE (2/18/11): On a lark I contacted Kensington Customer Support and they are sending me a new cord to replace the defective unit that I purchased previously.

I bought this cable to eliminate the whine heard on my portable XM receiver and my iPhone 4S. The product worked great on my XM receiver, but reduced the iPhone volume by 60%. When I increased the volume on my car radio to compensate, the whine returned.

I was all happy when I received my skydock through the mail. I immediately hoooked it up in my 2002 Chevrolet Silverado 1500 (non factory receiver). I then became instantly angry, because I would hear this terrible wine/hum/hiss coming from the speakers that would only get louder as I would accelerate. After researching, I read that it could be a bad ground, or some form of feedback from the alternator. This issue was not only with the skydock, but any accessory that I plugged into my AUX jack. So I asked a friend and he pulled up some filter on Amazon. As I went to pull up the page of the link that he sent, I saw this device as one of the items in the, "other people who looked at this item also bought this" section. There this item was, so I clicked on it and read all about it. I saw where other people who had the same issue as mine bought this item and were instantly satisfied, so I bought it. It came yesterday and I went and hooked it up, all of 3 minutes. The cord is a little long for the application, but I took care of that with a long clear twist tie and tucked the excess out of the way. I woke up this morning, and was on my way to work, and was like amazed. Not one hiss/hum/wine came form the stereo system. I could not wait to get to work and write this review. It works perfectly, and I have no regrets. I read where some people stated that it wears down easy, well it comes with a 2 year waranty, so if I do have that problem, I will just send it back in. People are too quick to throw away all of the packaging when they get stuff. My advice, keep all of the packaging and staple your Amazon purchase receipt for proof of the dates and file it in a drawer somewhere in the event you need it. I do not plan on continually plugging and unplugging mine. I bought it for the skydock and it will remain a permanent fixture in my vehicle. If it starts to wear, then I will update at that time. For now, I am loving it!

I bought this to remove the hum and whistle coming from my IPad and IPhone connected to my car. HUGE disappointment! This not only removed the noise, it reduced the sound quality of both bass and treble.

Those who gave this a good review must be either hard of hearing OR have a seriously poor sounding stereo in there car from the start.

Be forewarned...if you really like listening to good music in your car, this will make it sound terrible.

This cable does help cancel the 'buzz' of the charger feedback, unfortunately, it also muddles the sound quality. I use it for listening to audio books on long trips as the effect isn't really as noticeable but I can't really use it for music playback.
