Plugfones: Wireless Earplugs With Audio

There are a few different models of Plugfones; David Frane looks at the most basic corded model and a Bluetooth model. The corded version plugs into the jack of a smartphone or media device. The Bluetooth version allows you to listen to audio without a wired connection—and allow you to answer the phone or ignore a call with the push of a button—when paired with a phone or media device.
