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.
