Shock warning for iPhone, iPod users

iPhone and iPod users may experience a "small and quick" shock via their earbuds due to a build-up of static electricity, Apple has warned.

People listening to one of the devices in extremely dry air are most at risk of receiving a static electricity shock through the earbuds, according to a warning posted on Apple's website. The post likened the condition to the discharge that occurs when a person drags his or her feet across a carpet then gets a shock by touching a door handle.

However, Apple asserted that this condition did not necessarily indicate that Apple's equipment was malfunctioning.

"This condition is not limited to Apple hardware and static can potentially build up on almost any hardware and could be discharged using any brand of earbuds," Apple said.

Apple's warning didn't mention what prompted the company to issue the warning but a discussion thread on the company's support site showed a few users had voiced concern about the condition.

Apple made several suggestions in the warning on how to remedy the condition when indoors, including the use of a humidifier to raise the moisture level of the air, hand lotions to moisturise dry skin, or an anti-static spray.

The site also recommends users wear clothes made of natural fibres instead of synthetic fibres. When users are outdoors, Apple suggests users keep their device in a bag or a case to keep it out of the wind and refrain from frequently removing it from pockets as the rubbing may cause static build-up.
