When I was 7 years old I was given a Walkman (that should date me). On the first day of ownership, I set it down on a table, with the headphones on my head, and walked away. You can imagine what happened after. This isn’t such a huge problem now that electronic devices are drop tested and built to withstand regular freefall trips to the floor, but the idea of having a magnetic audio jack that disconnects when you tug is brilliant. It’s a lot like Apple’s MagSafe connector, only for your audio cables; plug one end into your device, while the other accepts your earbuds or headphones or anything you use to listen, and disconnects when pulled hard. More importantly, the makers have thought about making it possible to leave the MAGjack in (that’s the side that plugs into your device) without your phone thinking you have something plugged, so the sound isn’t routed to your earphones unless they’re actually plugged in. In this fashion, you don’t have any “installation” to do when you want to listen, you just have to snap the two halves together and you’re good to go. It’s pretty nifty, and it’s also cheap at $35, which gives you one MAGcap (the part that plugs into your earbuds) and two MAGjacks.
