HearDefenders-DF™
natural sound variable noise reduction ear plugs offer a unique set of
features including a durable silicone structure, two acoustic filters in
each ear plug, one of which is removeable giving you two levels of
attenuation, a form factor that lets you remove the outer filter and fit
them onto a standard two-way radio headset earpiece, a removeable neck
cord and a pocket carry case.
Dual Acoustic Filters
HearDefenders-DF™
ear plugs with both acoustic filters in place, give you an NRR 22 which
is ideal for motorcycle highway cruising, wear at really loud clubs and
concerts, shooting with small caliber weapons, airplane travel and use
in OSHA regulated industrial environments up to about 107 dB.
Single Primary Acoustic Filter Lowers Attenuation When You Need To Hear Better
Remove
the outer, secondary filter, and HearDefenders-DF™ become an NRR 12 ear
plug that is perfect for many applications in which you need to hear,
but with just a little lower volume. HearDefenders-DF™ with the primary
acoustic filter are ideal for clubs and concerts, for motorcycling in
the city, for professional musicians, for those with hyper-acusis and
other conditions causing excessive hearing sensitivity, as well as
industrial settings up to about 97 dB.
Variable Noise Reduction Depending on the Volume
(See
the attenuation chart above)
HearDefenders-DF™ provide a new kind of attenuation profile. As the
noise gets louder, the attenuation increases, providing greater
attenuation up to the full rated NRR of the earplugs only when needed,
and therefore allowing you to hear music and converse easily, but still
have the noise protection you need when you need it, all without
removing the ear plugs.
Enhances Two-Way Radio Headsets
HearDefenders-DF™
offer an excellent way to upgrade the ear tips on your two-way radio
headset. Just remove the outer acoustic filter and replace the hard
plastic tips that came with your headset, with your HearDefenders-DF™.
The primary acoustic filter then helps to protect your hearing from
gunfire and radio volume spikes, without interfering with your ability
to hear comm traffic. Most users find HearDefenders-DF™ a great deal
more comfortable than the hard tips that came with their headsets as a
bonus.
HearDefenders-DF™ are available in black or red-orange,
and in three sizes to fit nearly everyone, from about 5 years to adult.
Each pair comes with two acoustic filters in each plug, removeable neck
cord, pocket carry case and instructions for use. HearDefenders-DF™
carry a one-year manufacturer's warranty.
