Invoxia's AudiOffice, which just launched at Mobile World Congress, is for iOS-loving businesspeople. Pair your iPhone or iPad to the unit using Bluetooth, and you can enjoy enhanced sound quality (when using a corded handset), as well as a better microphone and speakers for greatly improved conference calls. AudiOffice uses "In Vivo Acoustic" technology, which eliminates echoes and background noise and supposedly makes you sound as if you were actually in the room with the person you're talking to. You can also use the high-quality sound system to play music from your device. The AudiOffice is available at the Invoxia site for $299.
