Sound in a Collapsible Lightweight Package
The UR40 delivers
digital quality sound in an ultra-lightweight design for listeners on-the-go.
The UR40 features dynamic elements for a wide frequency response from 15-22,000
Hz. A 2 mil. titanium coating on its diaphragms increases the rigidity of the
elements, minimizing mechanical distortion and ensuring exceedingly accurate
sound reproduction. Computer-optimized neodymium iron boron rare earth magnet
structures enable the UR40 to deliver greater volume, even with low-voltage
portable devices. Oxygen-free copper voice coils improve signal transmission
and conduction for cleaner, clearer sound. With its hybrid design, the UR40
combines the best of closed-style and open-style headphones. Closed leatherette
ear cushions form a light seal around the ears, enhancing bass frequencies.
Screened ear cups provide an open, hear-through sound that lets listeners stay
in touch with the world around them. The result is a full frequency, clean
sound that turns any recording into a "live"
At just over six ounces the UR40 wears
comfortably even after hours of continuous listening. The airy mesh sling
provides soft breathable support, ideal for those with touch-sensitive scalps.
An adjustable headband accommodates all head shapes and sizes for maximum
comfort. When not in use, the resilient, lightweight frame folds into a compact
configuration thats protective, easy to carry and convenient to store. Perfect
for travel, the UR40 includes a straight dual-entry four-foot cord. A
gold-flashed 3.5mm (1/8") plug, L-shaped to minimize cord stress, and a
gold-flashed 6.3 mm (¼") adapter are included.
