In the past, I’ve tried both aluminum foil and cigarette foil paper to block the iPhone’s GSM/Data interference from entering my car speakers (also notorious with computer speakers). Both worked okay, blocking most, but not all, of the speaker noise (I’d say about 80% was blocked).

Recently, I found a solution that blocks 99% of GSM noise, Static Free Bags (like the kind a new hard drive or RAM is packaged in):

Long time readers may remember my second post on corewerkz: How to prevent iPhone audio interference in speakers. Basically, I used aluminum foil to block the GSM cell-phone signals from getting into my car speakers (or computer speakers).

Although this solution kept the noise out of the speakers, and didn’t seem to effect cell signal, it did have an impact on bluetooth reception. I was getting lots of static when the iPhone was more than about 12″ from my bluetooth headset (both Plantronics and Jawbone). Needless to say, using bluetooth on a daily basis became a hassle.

I have found a new and improved technique that will keep bluetooth static to a minimum and the noise out of your speakers; instead of aluminum foil, use the foil-paper that you find in a pack of cigarettes. For whatever reason, it seems to block the exact right amount of GSM and keep bluetooth interference to a minimum. In fact, it may even block the speaker interference better – I haven’t heard a peep since the foil-paper.

Ever since I started listening to music in my car from my iPhone, I’ve been dealing with the annoying electromagnetic interference problem (loud buzz / static / popping / digital noise coming through car speakers). I set out to find a solution today, and to make a long story short, here’s what I settled on: taping two small pieces of aluminum foil on the back of the iPhone in a specific location, as seen below.

Here’s what I did:
