The SP-746 is a waterproof, wireless headset that has been certified with an IP67 waterproof rating - this specification means that the 746 is tested waterproof at a depth of 1 meter for a minimum of 30 minutes. Even if you are never in the water, this means that this headset is completely unaffected by sweat. This headset has been custom wired with a Hirose (four pin) connector to work with Audio Technica bodypack wireless systems. This unit comes with a microphone clothing clip that allows the user to attach the cable to their clothing. This microphone incorporates all of the heavy duty waterproof features as the H2O but does not have the detachable cable. Don't be fooled by imitators that actually charge more and then rust out!
