We know that a speaker microphone can improve effective communication and make using a radio more convenient. However, sometimes we overlook a related accessory that can also have a huge impact on user experiences...the earphone kit. The advantages of an earphone kit are that they make communications more discreet because only the radio wearer can hear the chatter on the radio, and they are easier to hear in noisy environments. They also don't call attention to the sound of a blaring radio, which can be important in crowds or sensitive situations.

Now there is a new, better kind of earphone kit. Incorporating hearing protection technology from SureFire™, The OTTO™ Earphone Kit with SureFire™ Noise Reducing Filters provides all the benefits of an earphone, plus protection from dangerous sound levels. It provides an option to either hear the sounds around you OR to block out 21dB of unwanted ambient noise, simply with the sliding of a switch.

The SureFire™ difference is situational awareness with impulse noise protection. SureFire™ Noise-Reducing Filters allow users to hear ambient sounds-including normal conversation-while reducing loud noises to safe levels. SureFire™ Earlock earpieces with Noise Reducing Filters have been used on shooting ranges for years, and now in partnership with OTTO™, SureFire™ technology is available for radio communication as well.

With OTTO™ earphone kits using SureFire™ technology, users can also close switches on the earphone to block up to 21dB of ambient noise, like the sounds of a crowd at a stadium. It only takes a second to switch from full situational awareness to effective hearing protection.

OTTO™ earphone kits with SureFire™ Noise-Reducing Filters are great for public safety officers, security personnel, stadium workers, and anyone working in loud environments. They are also backed by the OTTO™ guarantee of quality.

Both single-ear and dual-ear comm versions are available. Even on the single-ear comm model, OTTO™ provides a tethered second earpiece for SureFire™ protection for both ears.
