Sony Ericsson HBH-PV720

The Sony Ericsson HBH-PV720 is a Bluetooth headset that is designed for wirelessly taking calls from a Bluetooth-enabled device.  The headset is designed with a flexible earhook, volume controls, and a single multifunction button that is used for answering/ending calls, pairing, and redialing the last number.  It differs from the HBH-PV708 since it has an automatic volume adjustment feature to keep the sound loud in noisy environments but lacks the Fast Port and enhanced data rate of the HBH-PV708.  It also features adaptive frequency hopping technology to reduce wireless interference.  The HBH-PV720 comes with two sizes of earhooks and three coloured faceplates for customizing the headset.  It runs on a rechargeable battery that provides up to 11 hours of talk time and up to 800 hours standby.  The headset has a suggested retail price of $80 and includes a quick-release metal chain for wearing it around the neck when not in use.
