If you’re one of the unlucky few to still be rocking unshielded speakers around your work or living space, then you’re probably painfully aware of just how annoying that cell-signal “buzz” can be.

The problem is, speakers that aren’t shielded from electromagnetic (RF) interference will pick up on the radio frequency perturbations associated with incoming or outgoing cellular calls and interpret them as an incredibly annoying “buzz.” So, what do you do if you’re speakers are buzzing whenever you bring your iPhone too close?

iPhone RF ghetto shield

Well, if buying shielded speakers isn’t an option, you can just cut out a can of Sugar-Free RedBull and wrap it around your iPhone. The solution is reportedly quite effective (I’d give it a go, but all my speakers are shielded), and doesn’t seem to drastically affect cellular signal reception. The mod requires that you cut the can carefully in to a shape roughly approximately the iPhone and sticking it with some double-sided tape to the iPhone dock.

Docking the iPhone in the newly ghetto-fied dock gives you a much needed respite from iPhone (or any other cellphone) interference.

Oh, and make sure you use Sugar-Free RedBull – complicated quantum physics dictates aspartame trace.
