Paris, France — September 9, 2006 — RadTech, makers of iPod and
mobile computing accessories and more, today announces the debut and
immediate availability of Westone UM Series in-ear monitors with True
Fit technology at Apple Expo 2006 — Porte de Versailles, Hall 5,
Booth C-60.

Experience the best sonic reproduction possible, with noise isolation
far surpassing that of cumbersome and complicated active
noise-canceling phones. External isolation is a noise-silencing 30dB,
allowing listeners to hear the full dynamic range of recordings
without having to play them at unnaturally high volume levels. And
nearby people won’t hear a note – even when the monitors are driven
at full volume.

Westone monitors provide a pure and clean listening experience which
is unmatched by other earphones — listeners will discover new
dimensions of subtleties and instruments which previously went
unheard. The UM series’ low-profile and secure design practically
disappear when worn and they won’t fall out of the wearers’ ears,
even through very active use.

One key feature, Westone’s True Fit eartips, offers numerous benefits
over other tips; they don’t require rolling, squeezing, licking or
ear pulling to obtain a good seal. True Fit tips are constructed from
a softer and denser material that block outside sound and noise much
more efficiently. Two tip sizes are included to fit all users, and UM
Series monitors can be fitted with custom ear molds at any time.

Two models are currently available; the single driver UM-1 with a
frequency response which matches or exceeds that of most high-end
phones; 40-16,000 Hz. And the premium dual-driver UM-2 that far
exceeds the performance of virtually all other phones with an amazing
response of 20-18,000 Hz. Built to the highest professional
standards, The UM-2’s dual drivers and built-in passive crossover
combine to deliver the truest, studio-quality sound possible.

Westone’s UM-Series monitors transform virtually any audio system
into a rich personal soundstage, while providing industry-leading
levels of isolation, accuracy and sound output.

UM Series Monitors start at $109.95 US, and include four pair of True
Fit eartips, A zippered storage/carry pouch and a sound conduit
cleaning tool.
