In addition to its HBV-100 Bluetooth headset combination for computers. The package unites the company's existing PV705 Bluetooth earpiece with a special USB adapter that connects the earpiece with a PC for hands-free Internet telephone calls and other voice functions on a PC. The headset and USB adapter are already paired out of the box, Sony-Ericsson says; this eases the setup process for newcomers by limiting the installation to a simple driver installation.

The headset is not limited to computers, however, and can be linked to a cellphone for as much as 12 hours of continuous talk time or 300 when on standby. It includes its own rechargeable internal battery and a dedicated charger to recover power regardless of where the headset may be used. The HBV-100 is set to launch later this month, though pricing remains unlisted.
