INVISIBLE EARPLUGS?
================
The "Canal-Only" Style of the Model AF ear plugs and DisappEar color
option give you the closest you can get
to an invisible ear plug. A great choice for everyone who
loves to go to clubs and concerts, but who wants a natural sound hearing
protector they can wear without attracting unwanted attention, like, "Dude! I
didn't know you had a hearing aid!?"
|
Alpine is the primary provider of specialty hearing protection devices
throughout Europe, and now the benefits of the unique Alpine Tuned Acoustic Filter system are available
in the US through Ear Plug Superstore!
The unique Alpine Tuned Acoustic Filter System provides hearing protection that is
tuned to your specific application through selection of one of five
different filters. By closely following the frequency
response of the human ear, Alpine noise filters turn down the volume of the noise
you hear without distorting the quality of the sound you hear. That means you will
be able to hear the sounds you need to hear, accurately and comfortably, while
still getting the protection you need from dangerous or disturbing environmental noises.
Custom Natural Sound
Ear Plugs: Model ER vs Model AF
We also offer our Perfect-Fit™ Model ER and Westone Model 49 Natural
Sound ear plugs, both of which feature the Etymotic Research (ER) acoustic filters, the most popular
natural sound solution in the US. The ER filters offer a little more accuracy in
sound than do the Alpine Filters used in our Model AF, however you may find the benefits of our Model AF
outweigh the slightly higher sound accuracy of the ER filters. Model ER plugs come with two drawbacks: (1) the ER filters are large and cannot be hidden in the
ear canal, and (2) the ER filters are available only in three variations.
The
Model AF addresses both of these problems: (1) Alpine's Tuned Acoustic Filters are tiny, so they can be
installed in even the smallest canals for the least conspicuous solution
possible, and (2) Alpine's Tuned Acoustic Filters are available in five different attenuation levels for the greatest
flexibility, so you can choose a solution that accurately fits your unique hearing protection needs. Please note: our top recommendation for professional musicians
are the ER filter models.
For all other applications, we believe both types of filters offer excellent
results.
Alpine Tuned Acoustic Filters are installed in your Perfect-Fit™ Model AF Ear Plugs when they are made so they are shipped to you ready to
use. Alpine Tuned Acoustic Filters are then interchangeable; one set of filters
may subsequently be changed out for a different set of filters at any point. If
you later decide you want a different set of filters, you can order replacement
filters separately and install them yourself. Alternatively, you can send your
Perfect-Fit™ Model AF Ear Plugs to us, and we will change the filters
for you at no charge.
