Audio-technica (http://www.audio-technica.com) has released the
US$219.95 ATH-ANC7b active noise-canceling, over-ear headphones. The
ATH-ANC7b has the same 85% noise cancellation but incorporates
improvements from the previous model to offer even better sound
quality, comfort and convenience, according to the folks at
Audio-technica.
The ATH-ANC7b sports large-aperture 40 mm drivers and neodymium
magnets. The headphones employ QuietPoint active noise-cancellation
technology that detects environmental noise via miniature
microphones, and applies a corresponding sound-canceling signal to
block up to 85% of outside noise. The headphones are designedfor use
with the iPhone, iPod touch, iPod, portable music and DVD players,
laptop computers, in-flight entertainment systems and other devices.
The headphones have 109 dB sensitivity. The ATH-ANC7b also works when
the noise-cancellng function is turned off, and operates in passive
mode without batteries. The headphones fold for storage and come with
two 1.6 m (5.2-feet) and 1.0 m (3.3-foot) detachable cables, a
1/4-inch adapter, an airline adapter and a hard carrying case.
