The SWAH8-D AH8 AirLine 88 Wireless Fitness Headset Microphone Transmitter from Samson offers true wireless freedom without a bodypack or cable when paired with a CR88 wireless receiver (sold separately). It combines a micro transmitter and an adjustable gooseneck for a low-profile headset that molds to the shape of your head. It can be used to capture audio for Yoga, Pilates, Zumba, and cycling instructors. This model is intended for use between 542 to 566 MHz.
Featuring water-resistant components, including a marine-grade stainless steel gooseneck, sealed circuit board, and a AE50X micro-miniature microphone capsule, the wireless headset is built with an internal 8-hour rechargeable lithium-ion battery, gain and mute controls, and IR sync to wirelessly match the receiver and transmitter frequency.
