it's noise-cancelling Bluetooth headset day. At lunch today, Motorola rolled out two new noise-cancelling headsets, the flagship MOTOPURE H15 and the less-expensive H780. The new pair follow up the disastrous MOTOPURE H12, a noise-cancelling headset which in our tests did not actually cancel any noise.
The H15, at least, seems to be doing much better. Motorola dragged me around Grand Central Terminal in Manhattan to show off the noise-zapping functions, and I made several calls to both humans and robots. The H15 did a terrific job of cancelling the noise coming through my mic - the folks on the other end reported not hearing the background noise. But although they sounded clear to me, they weren't all that loud in the earpiece, and I found myself mashing the 'volume up' button futilely
The H15 and H780 use a new version of CrystalTalk, Motorola's noise-cancelling algorithm. Like Plantronics' recent Voyager 835, they use two microphones to detect and cancel outside noise, and alter both the sound profile that they're transmitting out and the frequency distribution in your own earpiece accordingly.
Both headsets have multipoint Bluetooth 2.1 for easy pairing to multiple phones and come with multiple earbuds to fit your ear. The smaller H15 has 4.5 hours of talk time; the larger H780 has 7 hours.
The MOTOPURE H15 will be available for $129 later this year. The H780 will be available for $99 later this year. (www.pcmag.com)
