Many accessories to mobile phones make the ease of talking while driving a big issue. You want to be able to stay in contact with others and have less distraction, right? Take a look at the Nokia Speakerphone HF-300 as an option for just that.
For a hands-free and cable-free choice, the Nokia HF-300 snaps on your visor or another object in your location and allows you freedoms that you might not have realized with an in-ear piece. The bluetooth technology used gives you a clear voice to both hear and speak with. Also features illuminated lights to keep things easy at night.
Has up to 20 hours of talk time using its own batteries and will turn itself off after a certain period of time to save those batteries for later chats. Nokia claims a powerful speaker and digital signal processing which will cancel out noises and other unwanted sounds. Sells for around $122 and comes in at 2.8 ounces so it's light and can be placed almost anywhere.

Motorola has had something similar to this and it’s been out for a while…
Motorola T305 Portable Bluetooth

I tried both speakerphones. While it’s on the visor, if you want people to hear you, you have to speak pretty loudly. If you pull your visor down just a little and closer to your mouth – it seems to work a lot better. Also, if you can get it to stay on your seatbelt instead (like I did with the first one)- it works so much better! If I’m in the car I use it because headsets usually fall off of my ears while I’m driving. Worth the money if you have the same problem. It’s $80. You can get it on eBay for about $50.
