What is the difference between the
QC
®
20 and 20i Acoustic Noise
Cancelling
®
headphones?
Both the QC
®
20 and 20i headphones can be used to listen to audio from
a variety of sources.
The QC20 headphones are specifically designed to work
with most Android™, Windows
®
and BlackBerry
®
smartphones. An inline
microphone and one-touch answer/end button allow for seamless
switching between your calls and music. Some phones may require you
to hold the answer/end button for a few seconds to perform these
functions.
The QC20i headphones incorporate an inline microphone and three-
button remote that provide more functionality with select Apple
products. With the inline remote control you can adjust volume,
play/pause tracks, skip forward/back on tracks, fast-forward or rewind
within tracks and change playlists. Depending on your Apple product,
you also may be able to answer/end phone calls, switch between calls,
and decline an incoming call. The microphone supports mobile
communications, and you can access certain voice applications, such as
VoiceOver or Voice Control, where available.
How much noise do the QC
®
20 and 20i
Acoustic Noise Cancelling
®
headphones
cancel when in Noise Cancelling mode?
It is difficult to establish one number that is valid for all the different
environments and situations where the headphones can be used. The
headphones will reduce unwanted noise to a level that is noticeably
more comfortable when compared to the same situation without using
the headphones. We encourage consumers to try it for themselves in a
variety of situations, both with and without an external audio source.
What type of sound quality do the QC
®
20
and 20i Acoustic Noise Cancelling
®
headphones provide when in Noise
Cancelling and Aware modes?
When powered, Active EQ, TriPort
®
headphone technology and low
noise floor enable QC
®
20 and 20i headphones to achieve high standards
in headphone audio performance. Active EQ enhances the clarity
throughout the entire spectrum of sound for lifelike audio reproduction,
while the combination of the seal created by the tips and TriPort
headphone technology structure fosters an accurate bass response not
commonly found in such small headphones.
Can you listen to music when the battery
runs down? What type of sound quality
do the QC
®
20 and 20i Acoustic Noise
Cancelling
®
headphones provide when
listening to audio when unpowered?
These headphones allow users to continue to listen to their source even if
the battery power is depleted. Without power, the combination of the
seal created by the tips and TriPort
®
headphone technology continues to
foster a bass response not commonly found in such small headphones,
but neither active noise cancellation nor Active EQ are able to function.
Audio performance in the unpowered state is similar to that of Bose
®
audio headphones (such as the Bose IE2 audio headphones).
