During our demo, Bose engineers emphasized that the key was to not give up audio quality over the added wireless functionality. And I'm happy to report they succeeded, albeit my impressions are based on a controlled setting -- I listened to simulated subway noises and a few songs inside a New York City building. Still, it doesn't take much to realize the potential of the QuietComfort 35. Bose says there are "night and day" improvements to the sound, designed to make sure that music is crystal clear whether you're listening at a low, mid or high volume.
Noise-cancelling works like a charm too, thanks to the combination of built-in microphones and a digital chip that sense the noise around you and block it accordingly. What's more, Bose claims the Bluetooth-powered QuietComfort 35 have 20 hours of battery life, or up to 40 if you use the included 3.5mm cable. If at any point the headphones run out of power, you can continue to use them -- the only thing you'll miss is the noise-cancelling. All in all, everything we mentioned above makes for a very intriguing package.
The QuietComfort 35 are available now for $349, and for £290 in the UK from mid-June.
