High-performance micro-size UHF wireless headset system from AirLine series that utilizes the latest in lithium ion battery technology and small, high-quality audio and RF components to bring performance freedom and convenience to a new level. To eliminate continually changing batteries, Samson has designed this micro-size UHF wireless 600 MHz system to be fully rechargeable, supplying lithium-ion rechargeable batteries and USB DC power inputs for both the AH2 micro-size ear-set transmitter and AR2 receiver. A handy docking station for the receiver also provides a USB DC input and a 3.5mm balanced audio output. The complete ear-set transmitter offers total freedom and uninhibited movement. It features an omnidirectional microphone to ensure the voice is picked up and amplified even during periods of fast, heavy movement. Plus, its water resistant design protects the microphone and transmitter from moisture and perspiration that can accumulate during intensely active performances. The wireless receiver boasts meticulous engineering that provides professional sound reproduction and exceptional reliability. Like the transmitter, it also houses a rechargeable battery that will offer about seven hours of operation, as well as 3.5mm unbalanced mic/line level output and USB DC power input.
