reduction technologies. They use a sophisticated proprietary electronics

approach to active noise reduction, placing microphones both inside

and outside the earbud. The electronics system senses the sound in

almost any environment and then measures, compares and reacts –

instant by instant – to produce an opposing cancellation signal. New,

patented tip technology from Bose creates a gentle seal at the entrance

to the ear canal that enables full-spectrum noise reduction.

In Aware mode, Bose

microphones within the earbud to pick up surrounding sounds and send

them to the user's ear. This makes it possible for the user to hear what is

going on around them while still listening to their audio. At the same time,

Aware mode enhances the listening experience by maintaining a

minimal amount of noise reduction to block certain background noises

while still allowing the user to be aware of most ambient sounds.

As with any headphone, the signal from the audio source can dominate

the ability to hear your surroundings. If the source volume is at a

moderate level, Aware mode will provide the user with the ability to hear

their surroundings.

Proprietary TriPort

maintaining a small size. The result is better audio and active noise

reduction from a smaller, lighter, more comfortable headphone. TriPort

headphone technology is used in all of our consumer headphones.

Active EQ (equalization) involves electronically tuning the frequency

response to closely match the proprietary Bose

headphones. The closer the frequency response comes to matching the

target curve, the more lifelike the audio performance.
