We’ve all had dust, grit, or some liquid fall into our headphone jack on our mobiles, only to find the sound is now just a little bit wonky (and if you haven’t yet, count your blessings). Well it seems there’s now a solution for this, and it’s been invented by an Aussie.

Called the iCatchi Plug, this simple device is a plug designed to block your 3.5mm headphone jack when it’s not in use. It comes in lots of colours, designs, and costs $7.95, making it an easy and affordable solution to stopping dirt or water from getting into your headphone hole.


Every iPhone has a liquid contact indicator inside the headphone jack, including the iPhone 3G/3GS (left) and iPhone 4 (right).

Liquid is, sadly, one of the easiest ways to damage your phone. Most smartphones have what’s called a “liquid contact indicator,” a tiny sticker that will change colour when exposed to water, usually from white to red. If the indicator is red, the manufacturer of your smartphone – such as Apple, HTC, or BlackBerry – might not cover the repairs of your headphone port if it ever gets ruined.

While some companies are beginning to relax their conditions, the iCatchi looks like a great option for anyone at all concerned about accidentally damaging their phone when it rains.


The iCatchi comes with different designs and in different sizes.
