If you are like me, you like to use your mobile device to listen to music. If you don't need a huge 40gig library of mp3s with you, an SD card works fine. But at times it would be nice to have the music without all the ambient background noise of people talking around you. There are headphones built for that purpose, like the
Etymotic ER6 Isolator earphones. I picked those only because they were the first Google item returned, but ironically it turns out that they are sold by Palm as a
LifeDrive accessory also!
Well, you can make your own set from swimming earplugs. Instructables has the
information you need. But don't drive or ride your bike with these things in, and don't blame me if you blow your ears out. You've been warned!
