ACTIVE NOISE REDUCTION | COMFORTABLE

FOLDABLE | SUPERIOR AUDIO

The superb-sounding Altec Lansing AHP712
headphones with Active Noise Reduction are ideal 
for the frequent traveler and anyone in a noisy
environment. Active Noise Reduction technology
uses small microphones to “listen” to ambient
sounds and special circuitry to create a sound wave
180 degrees out of phase from the ambient sounds.
When the sound wave is played through the
headphones, it reduces ambient noises, such as
airplane engines and subway rumbles, to allow you
to focus on your music, movies or games.
