Sony Ericsson can be pretty schizophrenic when it comes to mobile phone speakers. While it has some prettyat one end of the spectrum, it can be utterly practical at the other. Take, for example, its new car speakerphone.
The Bluetooth HCB-150 clips onto the visor as do many others, with 25 hours of talk time and 700 on standby. But it has a particularly convenient technology that stands apart from the competition: A "text to speech" feature literally tells you who's calling, according to SlashPhone. That way, you can ignore those after-hours office calls without taking your eyes off the road.
