The headphones use XXL speakers with patented Varimotion
diaphragms
for a dramatically improved sound.
A swiveling external antenna on the transmitter and a
digital
antenna diversity
receiver maximize signal quality and minimize
dropouts. All signal processing is performed in the digital domian
to maintain the full dynamic range. The
sound quality of the
headphones is
equivalent to that of a high-end hardwired
model
. The self-adjusting headband made of genuine leather
looks great and it gently and automatically conforms to every head.
