Patriot-F+™ High Noise Surveillance Series Earpiece Patriot-F+

Patriot-F+™ High Noise Surveillance Series Earpiece

Professional Armature Speaker for High-Noise Enviroments. The highest quality speaker made is now built into this all-new Patriot-F+ earpiece.Works with Kyocera Dura Series on Sprint PTT Network and Casio Ravine, and Samsung Convoy on Verizon PTT Network. It uses an armature device that acts like a piston going up and down to create the sound - it is this sound that is the closest to True Voice. It eliminates most of the bass, which is only needed when listening to music. This optimizes the high frequencies for voice clarity. Most earpiece speakers use a moving diaphragm that vibrates, the subsequent vibration produces a dull, bass sound.
