Wouldn't it be nice if you could use a single bluetooth headset with both your office desk phone and your cellular phone? Actually you will be happy to know that you can and it is very easy to do. I bought a GN 6210 Bluetooth wireless headset for from Hello Direct and it is an amazing product. It paired with my TREO in about 20 seconds and has worked seamless. The GN 6210 comes with a charging cradle/dock that connects to your desk phone and with a push of a button you can toggle between your cell phone and your desk phone...meaning you can use the same headset with both devices. I have been in my office on my desk phone using the headset...got a call on my cell phone, asked the desk line called if I could put them on hold, then answered my TREO and toggled my headset onto the TREO...finished the call and then toggled back to the desk phone with another push of the button.
If you want a simple to use headset that has a long batter life (8 hours of talk time) I really like the GN 6210. If you have seen the Jabra BT250 headset...the GN 6210's actual headset looks pretty much identical but comes with desk dock. I paid roughly $200 for mine through Hello Direct but they now are offering a reconditioned model for only $99. If you want to squeeze some extra work into your day this is an easy way to turn up your productive time to a new higher level.
