A friend and I went to Fry's today, and he bought the no-name Bluetooth headset currently on sale there for $18. I was chagrined, once we got it home, to find that it supports roughly the same feature set at the $70 Plantronics I bought there a few days ago, including good support for the handsfree profile…
I'm still trying to decide whether to return mine and purchase one like his; I doubt it though. Mine is supposed to be slightly more noise immune, and it's pretty comfortable. In any case, I'm not sure I even have the packaging anymore. Oh well; learning experience.
We also found that my friend's phone, a Motorola Razr V3, does support voice dialing. I looked at the online manual without success; he found out how to train his voice dialing by playing with the phone. The only information in the manual about this feature seems to be buried in a section called "Learning to Use Your Phone" in a subsection called "Using the Phonebook", on a second page which isn't obvious from the PDF. Once I knew the phone did voice dialing, I eventually found the feature in the manual by PDF keyword search.
Looks like the current standard cellphone configurations are being shipped automotive-ready. Nice change from a year or two ago. (B)
