Sound system bridges music, phone

As the evolutionary convergence of the mobile phone and media player forges ahead, so too do accessories that play to both camps. The "B-Tube" from Linx, for example, is a portable stereo that can be used as a sound system or a speakerphone.

Using Bluetooth 2.0 connections, the aluminum cylinder can transfer MP3 music wirelessly from a phone or computer or allow hands-free conversations with its built-in microphone. TechShout says it's also small enough to be stored "just about anywhere." Just be careful not to mistake it for a cigar tube.
