Nokia recently unveiled their new Nokia Lumia 920 and Lumia 820 Windows Phone 8 handsets and they have also introduced their latest audio accessories. In a collaboration with Monster, the Purity Pro Wireless Stereo Headset delivers stereo sounds through a Bluetooth connection and features Monster’s active noise cancellation technology. The noise cancellation activates automatically when the headset is unfolded to block out ambient noise. The headphones have been created to color-match the available vivid phone shells offered with the phones themselves. You can view the phones alongside the headphones below which will be available later this year.
