I refuse to own brain dead GSM phones for this very reason. Computers, Cars, Audio Systems, Headphones, Sound Docks anything with a Speaker is vulnerable. I love when I hear a broadcast on the Radio or TV and the person they are interviewing transmits the "Beeeeeeep daht daht daht..." to the microphone. Same folks that worry about using "Power Plug" transmission, or spend massive dollars on power filtering then buy one of these EMI noise bombs.

If you think listening to music is fun, try learning an instrument.
