Dual-mic noise cancellation uses a microphone pointed outwards to test and analyze background noise. It's a pretty common method of noise cancellation. According to Plantronics, what they bring to the table is AudioIQ, an algorithm that alters sound both in the earpiece and the transmitter, rather than just the sound the person on the other end hears.

Unlike the Aliph New Jawbone, the 835 is designed to work best in middle-of-the-road noise environments - out on the street, or in a car with the top down - and not in hyper-noisy situations, Plantronics said. They said they've tuned the headset to The Plantronics Voyager 835 gets 5 days of standby and 5 hours of talk time, and it will be available immediately.

We're pretty interested to review this headset. Plantronics makes some of the best sounding headsets on the market - their Voyager 510 and 520 are two of the best Bluetooth headsets ever, and their 925 isn't so bad, either. But they've also had some voice quality missteps, notably in their 665 mini-headset. We're hoping the Voyager 835 is worthy of the Voyager name.
