My new Treo 680 has built-in bluetooth connection, which is pretty much a standard feature of all new cell phones. To get the most out of my new phone, I set out to buy a bluetooth headset so that I can talk wirelessly. I browsed alot bluetooth headsets and eventually decidded to get the Plantronics 510, which is PC Magazine editor’s choice. The 510 looks quite stylish, unlike other bluetooth headset with a big chunky module clip to the ear, the hardware module of the 510 is very light, compact and hidden nicely behind the ear. Just like any other bluetooth headset, the 510 is very easy to use, just fully charge it, turn it on, pair it up with the phone and you are ready to go. The voice quality is very clear and it has a good range. I can walk around my apartment without losing connection. Using the wireless headset is more natural than holding the phone or with a wired headset. It feel like talking face to face instead of on the phone. I can even have noodle soup and talk at the same time without feeling awkward. You will never go back to the old way once you had experienced a wireless headset.
