As we mentioned, the Voyager 520 has a dramatically different look from that of the Voyager 510. Going for a more contemporary look and eschewing the Borg-like design of the 510, the Voyager 520 has a simple tear-drop Bluetooth headset design. It is long and narrow, measuring about 2.5x0.7x0.5 inches and weighing close to 0.63 ounce. We can't say we're too thrilled with the style of the headset, since it does look a little conspicuous when you're wearing it, and the black-and-silver color scheme is a tad dull.
But the design isn't the important thing--it's the fit and comfort that count. And it's here that the Voyager 520 shines. Behind the headset is a simple in-ear earpiece that sits comfortably just inside the ear canal without any discomfort. The Voyager 520 also has an ear hook that's made out of a really flexible silicone material, and it can rotate to fit either ear. We were able to wear the headset for hours without any problems at all.
Probably our only real gripe with the Voyager 520 has to do with the multifunction toggle, which can be pressed down for handling calls, and acts as a volume rocker when moved up and down. Pressing it down was easy enough, since it juts out above the surface of the headset. However, toggling the rocker up and down can be a tad tricky. The switch often felt quite stiff, and sometimes our fingers would slip off the rocker when trying to move it. Above the toggle is an LED that glows blue or red depending on the function.
Unlike the Voyager 510, the Plantronics Voyager 520 doesn't come with too many extraneous accessories aside from a charger and a charging cradle. You can, however, purchase additional accessories from Plantronics.
We tested the Plantronics Voyager 520 Bluetooth headset with the BlackBerry Pearl. The pairing process went very smoothly, especially thanks to Plantronics' QuickPair system that automatically sets the Voyager 520 to pairing mode the moment it's turned on. Once it's paired, the QuickPair mode will remain inactive until the devices have been unpaired. Call quality was really good, probably thanks to Plantronics' AudioIQ technology that reduces background noise and enhances the sound of the natural voice. There was some disturbance in windy environments, but it wasn't too serious.
Other features of the Plantronics Voyager 520 include the typical ability to answer, receive, and end calls; last number redial; voice dial support; the ability to transfer calls from the headset to the phone and vice versa; as well as a battery indicator. You can also pair it with more than one Bluetooth device, then toggle between the two with the Voyager 520's MultiPoint technology. The Voyager 520 has a rated battery life of 8 hours of talk time and a promised standby time of 7.5 days.
