Humidifiers are the new must-have iPod accessoryWritten by Duncan under Humidifiers | 1 Comment
They say, “It’s possible to receive a small and quick electrical (static) shock from your earbuds while listening to iPod or iPhone.” And go on to recommend, “raising the moisture level in the air of the local environment by using a portable humidifier” as “Very low humidity (dry) environments are conducive for static buildup.”
Other things they say you can do to avoid a shocking experience whilst iPodding indoors include using an anti-static spray on the air and using hand lotion (on our hands or our ears?) or wearing natural fibres instead of synthetic. When you go out and about they recommend keeping your device in a bag or case and avoiding rubbing it on materials by not taking it out of your pockets frequently.
If none of the fixes above work, you could try some of this fancy anti-static footwear . Not sure if the straps will be long enough to stretch to your iPod though.
