These headset-microphones use a
digital voice system and have an active noise reduction feature, along
with an electricpowered microphone. Because on-ear headphones are less effective at providing passive
noise reduction (the physical blocking of noise), Bose engineers had to

headphones. Telex is introducing three new active noise reduction (ANR)
headsets under the Stratus brand name. |
