We saw what are currently available in terms of retro style Bluetooth headsets, but here's what they need to do, in spirit of the second pillar, classiness.  The headset would be about as small as the plain ones, but it would be able to fit securely in your ear with a rounded flared ear piece similar to ones you see on piezo electric earphones.  It would still be a two inch ma bell receiver style, available in light blue and tan beige.  The crystal radio set pages linked from our site shows pictures of the kind of piezo phones we're talking about.  It's better than a conventional set of ear buds, because it stays in your ear instead of dropping out like ear buds do.  Ear buds rely on that cartilage gap being small enough to accommodate a thin audio wire, but that's only true of true believers of The Responsibility Age, because being such causes their ears to be exactly shaped the right way for the ear buds.  If Microsoft were an automaker, new car seats will force everyone to have the same size butt.
