What are the Bose QuietComfort 45 Headphones?
Bose QuietComfort 45 Headphones is the successor to QuietComfort
35 Series II. They deliver high-fidelity audio performance and
world-class noise cancellation that allow users to hear more of
their music and movies - while traveling, at the office or at
home. QuietComfort 45 delivers a new Aware Mode, improved battery
life now up to 24 hours, and an updated design.
Bose QuietComfort 45 Headphones?
QuietComfort 45 Headphones offer the same unmatched combination
of audio performance, while delivering improvements in key areas
such as ANR performance, voice pick up, and up to 24 hours of
battery life. In addition to the performance improvements,
QuietComfort 45 introduces a new Aware mode, a noise rejection
array for clear calls in noisy environments, and connects with
the Bose Music App.
Product Technology
What is Acoustic Noise Cancelling headphone technology?
Acoustic Noise Cancelling headphone technology is a method of
reducing unwanted noise by electronically creating a signal that
is the mirror image of the unwanted noise. Microphones in the
earcups monitor sound at the user's ear and externally. The
monitored sound (music and noise) is compared to the sound the
user wants to hear (the signal coming from the audio input - this
could be music or silence). The difference between the monitored
sound (from the earcup's microphone) and the sound the user wants
to hear (music or silence) is noise. The electronics in Bose
QuietComfort 45 Headphones instantly process the noise signal,
and a precise equal and site signal (correction signal) is
created. This site signal is then sent to the speaker in the
earcup along with the sound the user wants to hear (again, this
could be music or silence). The result is three signals being
presented to the user's ear: noise from the environment, the
sound the user wants to hear, and the correction signal from the
electronics. The noise and the correction signal nearly cancel
each other, providing a clean, high-fidelity sound signal at the
ear.
What is TriPort acoustic headphone structure?
Proprietary TriPort acoustic headphone structure utilizes
external ports to vent the earcups and effectively the
acoustic volume, without increasing the size of the earcup. The
result is better audio and active noise reduction from a smaller,
lighter, more comfortable headphone. TriPort acoustic headphone
structure is used in all our consumer headphones and headsets.
How is the total noise cancellation in Bose QuietComfort 45
Headphones achieved?
Bose QuietComfort 45 Headphones utilize both active and passive
noise reduction technologies. They use a sophisticated
proprietary electronics approach for active noise reduction,
placing microphones both inside and outside the earcups. The
electronics system senses the sound in almost any environment and
then measures, compares, and reacts - instant by instant - to
produce an sing cancellation signal. Meanwhile, passive noise
reduction is achieved by the combination of earcup fit, design,
and clamping force of the headband.
What is Aware Mode?
Aware Mode turns on the external microphones of the QuietComfort
45 Headphones and feeds ambient sounds into the headphones,
enabling awareness of the sounds in the environment, such as cars
and emergency vehicles, while still enjoying audio content. When
there is no music playing, the effect is that it feels like
you're not wearing headphones at all.
What is Active EQ?
Active EQ (equalization) involves electronically tuning the
frequency response to closely match the proprietary Bose response
curve for headphone audio. The closer the frequency response
comes to matching the target curve, the more lifelike the audio
performance.
What is full-spectrum noise reduction?
Think of a piano keyboard as the full spectrum of human hearing,
from the low notes at one end, to the mid-range notes in the
middle, to the high notes at the site end. Through a
combination of advanced active electronics and passive
attenuation, Bose QuietComfort 45 Headphones reduce noise across
the full range of human hearing (all the keys on the keyboard).
Other noise reduction headphones may be effective at only some
frequencies (only some of the keys on the full keyboard).
What is electronic noise floor?
Noise floor is the electronic "hiss" that may be heard with some
noise reduction headphones. This noise can be annoying and can
take away from listening enjoyment. Bose QuietComfort 45
Headphones use sophisticated electronic circuitry to minimize
noise floor and make it virtually undetectable. This is
especially important when using the headphones in transparency
mode, where you're feeding sounds of the outside world into the
driver signal. Noise in the system can be ampflied, impacting the
naturalness of how you hear the outside world.
What is Bluetooth technology?
Bluetooth technology is a wireless standard used in mobile
devices to wirelessly connect them to headphones. This standard
allows for audio to be transmitted wirelessly to the headphones.
The standard also supports microphones for communications;
multi-point, the ability to connect to two mobile devices
simultaneously; and a remote to control your media.
What is A2DP?
A2DP is a Bluetooth profile that streams stereo audio content.
Using A2DP, Bose QuietComfort 45 Heaphones allow you to listen to
videos, music, calls, and podcasts wirelessly from a Bluetooth
mobile device.
What codec do Bose QuietComfort 45 Headphones support?
A codec is a digital audio encoder and decoder used to transfer
data to Bluetooth audio devices like headphones and loudspeakers.
Bose QuietComfort 45 Headphones support the Low Complexity
Subband Coding (SBC) and the Advanced Audio Coding (AAC) codec
standards.
What is multi-point?
Multi-point is a technology that allows Bose QuietComfort 45
Headphones to maintain a connection to two devices at the same
time so you can, for example, conveniently watch a movie on a
while still being connected to your phone. Bose software
will then seamlessly transition between the two devices when you
have an incoming call so you're always connected to the active
source device
Product Performance
How good is the audio performance of Bose QuietComfort 45
Headphones?
A combination of technologies enables Bose QuietComfort 45
Headphones to achieve high standards in headphone audio
performance at any volume setting. Volume-optimized active EQ
enhances clarity throughout the entire spectrum of sound for
lifelike audio reproduction. TriPort acoustic headphone structure
fosters a bass response not commonly found in such small
headphones, and a low noise floor reduces the annoyance of an
electronic hiss commonly found in other noise reduction
headphones.
How much noise do Bose QuietComfort 45 Headphones cancel?
Bose doesn't make cls about percentage reduction because it is
difficult to establish one number that is valid for different
environments and situations. Bose QuietComfort 45 Headphones
reduce unwanted noise to a level that is noticeably more
comfortable when compared to the same situation without using the
headphones, especially in noisy environments like an airplane or
a train. We encourage consumers to try it for themselves in a
variety of situations, both with and without an external audio
source.
How durable are Bose QuietComfort 45 Headphones?
Bose QuietComfort 45 Headphones use proprietary materials
specifically engineered to be comfortable and light while
exceeding rigorous product quality testing. Glass-filled nylon is
used to achieve a high level of durability while maintaining a
light design. Stainless steel is used for the headband spring and
pivots to ensure the headphones are durable enough for everyday
use. They carry a one-year limited warranty in the U.S. for
defects in materials and workmanship.
How comfortable are Bose QuietComfort 45 Headphones?
These headphones were designed to maximize all the features that
contribute to user comfort, especially when using the headphones
for extended periods of time. All materials have been selected
for their comfort and lightweight properties. Protein leather is
used for its comfort, durability, and acoustical properties. The
earcups rotate easily for a uniform, comfortable seal. And most
importantly, stability is achieved with minimal clamping force,
allowing for hours of comfortable wear.
