With no new features, Sony Ericsson’s three new headsets have got nothing more than having new names. Anyway, the list includes HBM-75, which is a run-of-the-mill wired stereo earbud set, the HBH-PV702 and the HBH-PV710. Both the latter are Bluetooth headsets with the same pen-shaped make. Where is the innovation Sony? The HBH-PV710 comes colored in brown and red and has a standby time of 12.5 days. The PV710 will be out for sale in late winter, the PV702 in early spring, and the HPM-75 in late spring this year. No words on pricing.
