Bose Noise Cancelling Headphones 700 Faq

What is the difference between Bose Noise Cancelling Headphones 700 and QuietComfort 35
wireless headphones II?
Both QuietComfort 35 headphones II and Bose Noise Cancelling Headphones 700 are wireless
Bluetooth headphones. For music, both are engineered with proprietary active equalisation, so
they avoid boosted bass, vocals and treble that create listener fatigue over time, opting instead
for faithful reproduction that's clear, natural and balanced. Both headphones also feature
controllable noise cancelling; however, while QuietComfort 35 offers three settings, Headphones
700 offers 11—including a full-transparency experience that gives the term "off" an entirely new
meaning. While the highest setting delivers the most powerful silence, the lowest lets your
surroundings pass through the earcups fully—so with the flick of a switch, you hear yourself,
others and everything else like you aren't wearing a headset at all. Conversation Mode lets you
gain the same awareness while enjoying content—so you can pause entertainment and noise
cancelling simultaneously, chat face to face or listen for announcements, and resume where you
left off when you're done.
How does the noise cancelling in Bose Noise Cancelling Headphones 700 work?
Bose Noise Cancelling Headphones 700 use both active and passive noise reduction
technologies. Active noise cancelling relies on a sophisticated proprietary-electronics approach
using microphones both inside and outside the earcups to monitor the sounds around you and
instantly produces an opposite signal to cancel the noise. Meanwhile, passive noise reduction is
achieved by the combination of the acoustic structure and the earcup fit.

What is TriPort acoustic headphone structure?

Bose Noise Cancelling Headphones 700 feature our proprietary TriPort acoustic headphone
structure, which uses external ports to vent the earcups and maximise the acoustic space inside,
so your audio content sounds big and bold.
How many microphones do the Bose Noise Cancelling Headphones 700 have?
Bose Noise Cancelling Headphones 700 feature a total of eight microphones. Six microphones
dramatically cancel noise, so it doesn't reach your ears. Two of those microphones combine with
two others to dramatically improve voice pickup. A beamform-array isolates your speech,
suppressing everything else that's audible. A rejection-array adds a second line of defence,
tracking then blocking the most disruptive remaining sound—from a coffee grinder to other
dialogue nearby. It all happens in real time, adapting as you move or your environment changes.
It works with any VPA, any phone paired to the 700s, or any phone or phone/headphone
combination on the far-end.
