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.
1) Will it work "backwards"?
2) Will it attenuate sound?
So here's what I discovered:
1) It most definitely works "backwards". Since the car kit necessitates me placing the output from my phone into the "input" side of the device, I really had no choice on how to "route" the signal. Immediately I noticed a tremendous improvement. The whine is still there, but I need to turn the volume up to 30 to hear it at all during a pause in playback. Since I normally listen at 10-15 which is plenty loud for me, this was a non-issue. It did what I needed it to do perfectly, the whine is not audible at idle during silence between tracks, the whine is not audible at 60+ MPH during silence between tracks.
2) This was the big concern for me as several reviews mentioned this cut audio and killed frequency response. The music was just as loud, and using the "8 Mile" soundtrack as my testing album, bass response was just the same, deep and powerful. Highs were crisp and clear. This device did not attenuate sound at all.
The only thing is that the jack sleeve is a bit thick to ensure a solid insertion into my phone's headphone jack with the case on. So I need to remove the case in order to ensure a good connection. I almost docked a star because of this, but that is not really a flaw with the device. If you have a loud whine while charging your phone and listening via Aux-In and are on the fence about this device, don't be. It works, and works great.
1. Removes static
2. Decent cord length
1. Muffles sound.
2. Does not work well if trying to use the stereo system as a hands-free phone device. The other end hears screeching feedback.
3. Male to female connector means you still need your own audio cable to compliment this.
I bought this to remove the static sound when my phone is playing music while charging. This magically turned it into a silent audio experience. I don't mind the audio being muffled since I'm not into the high fidelity audio stuff. However, I used an audio cable with a built-in microphone button to turn my stereo system into a hands-free calling system. This device kills that feature completely as the person on the other end hears nothing but feedback when they talk - Four stars
Update: 3/6/2013 - Exactly 3 years and one month later -
I recently bought a Bluetooth receiver to use as a hands-free device in the car. It works well enough, except for the constant static hiss because the receiver uses the car's USB power. So I dug this unit up from storage and chained it between the Bluetooth receiver and the stereo system, and the hiss miraculously disappeared, without any loss of sound quality experienced using the direct wired method. I changed the rating to 5 stars for that.
