We are often asked what makes our iPods the best. Unlike other waterproofing processes, we completely encapsulate all of the electronic components in sealant. The inside of our shuffles are entirely filled with sealant resulting in no voids or empty air spaces. Because of this difference, there is no way for water to access the electrical components. So when people say our waterproofing is “solid”, it’s not just a figure of speech. Other waterproofing techniques try to use sealant to fill in the gaps in the shuffle housing to prevent water from entering. This method results in empty space between the sealant and the electronics it is meant to protect. Because there is empty space inside the shuffle, as the external water pressure builds it is eventually able to push the sealant out of the way, into the empty space, and allow water to enter. In contrast, as the pressure builds on our shuffles it simply presses the sealant harder against the electrical components. This is the why we are able to get much better depth ratings than other companies. Other companies often disable the on/off slider on their shuffles because using it over time will dislodge the sealant around the slider. Since the entire inside of our iPods are solid sealant, moving the on/off slider back and forth still doesn’t give the water any way to access the internal components. On our shuffles all of the buttons work, and there aren’t any absurd limitations like not being able to plug in the headphones while submerged.
