The New York Times' David Pogue looks at the progress of what he calls the "personal audio odyssey," noting that "you can now buy a single pair of wireless headphones that bring both cellphone calls and iPod tunes to your ears."

These headphones, Pogue says, include the Motorola HT820 for $84 and the Plantronics Pulsar 590a for $121 -- and, he says, "they work beautifully."

The idea is simple, but what it enables is amazing. "You walk along, listening to music from the iPod in your purse or briefcase," Pogue writes. "If someone calls your phone, you hear a pleasant chirp in the headphones. You tap the big Call button on the earpiece; the music pauses automatically, and you're connected wirelessly to the cellphone in your pocket. When you tap to hang up, the music resumes automatically. No swapping of ear equipment is ever required."

Oakley's O Rokr sunglasses for $250 do the same thing, and they have the added advantage of looking like cool shades rather than bulky headphones.

What's missing from this equation, Pogue notes, is a Bluetooth-enabled iPod. There are third-party solutions to solve that problem -- but it's just plain silly that Apple hasn't yet taken that step, adding both Wi-Fi and Bluetooth to the device.
