Phone Headsets

The cs50 works on 900mhz, just like your old cordless phone at home. I believe there are 11 channels available with 900mhz, and after that you get cross talk.

The voyager 510 is bluetooth, which is 2.45mhz. I love wikipedia.

What's more important than the radio frequency is the modulation method and protocols used. The CS50 is spread-spectrum. Some cordless phones use this too (but not all 900 MHz phones do, so you have to check carefully). Spread-spectrum's security is pretty good. For what it's worth, the CS50 is currently the only wireless headset that is approved by our company to use for company business.

Bluetooth's security was almost nonexistent in the original version. I know that a lot of work has been done on it, but I don't know what the status is at this point.

One other thing: Plantronics makes good stuff. That's what NASA people all use. I've had to wear one for 18+ hours at a time during missions, and they stay pretty comfortable. My personal preference is a full-coverage headset; I've never gotten comfortable with the in-ear ones.
