SLVR), or use a hydra-headed contraption like the Plantronics MX-100 headphones, you've probably missed a few calls when you've been cranking the tunes. At the very least, you've had to deal with the dreaded headset shuffle, as you frantically swap earbuds or cram your phone over your ear. UK company Mavizen has come up with what may be a better solution, in the form of the Blueye, a Bluetooth device that you connect to the earphone jack of an audio player and then pair with any Bluetooth phone. You then connect a headset to the Blueye, and listen to your music. When a call comes in, Blueye mutes the music and routes the call directly to the headset. Of course, there are some tradeoffs: the music is just muted, not paused, and you're stuck using a wired headset with your Bluetooth phone. But unless you really do use a musicphone as your main source of sounds (and we're not saying there's anything wrong with that), this could be reasonable solution. Or you can just keep missing calls. That's what voicemail's for, right?
