The human race enjoys shoving plastic and metal into (or around) the ear, but a new patent shows just what Microsoft had in mind to make this more enjoyable for those who listen to music while on the go. Think headphones, think Zune, now think of both of those connected as one, slapped on top of your skull.
As one can see in the above image, the headphones enable the user to connect a Zune music player to the side, while the opposite connector is free for rechargeable battery packs, storage extensions, WiFi adapters, and more. The Zune device looks to be a fairly minute music player, presumably along the dimensions of the Apple iPod Nano.
According to the documentation, the headphones could also house controls to operate peripherals, not to mention an optional microphone and even USB ports. It's an interesting concept that allows the consumer to personalise the headphones to suit the individual needs.
The only downside is this patent was filled back in 2008 and we know that Zune hardware is no longer with us. Who knows, perhaps Microsoft also planned to include voice control - "Beam me up Ballmer!"
