  • Tiny but Mighty

    The AH2 earset microphone transmitter features a micro design that places the entire transmitter comfortably behind the ear for a secure, comfortable fit without wires or a belt pack. Don't sweat the small stuff, the AH2 is protected from moisture and perspiration by a specially treated water-resistant coating. The omnidirectional microphone ensures that your voice is clearly picked up and amplified for speaking or singing. A single multifunction button serves as a one-touch mute, volume control, and power switch.

    Take Your Wireless Anywhere

    The freedom to take your wireless with you has never been easier. The AR2 receiver offers the convenience of portability at a fraction of the size of other wireless receivers. The AR2 has a 3.5 mm unbalanced mic/line level output that can be connected directly to mixers, PA systems, or even small portable speakers. The handy AR2D dock provides a secure base for charging and has its own 3.5 mm balanced audio output. Tone key and auto-mute circuitry ensure wireless performance free of noise, dropouts, and interference. A zippered carrying case is included with the Airline Micro Earset Wireless System.

  • Gone Are the Days of Changing Batteries

    The AirLine Micro system is designed to be fully rechargeable, with lithium-ion batteries in both the transmitter and receiver. For convenient charging, both the AH2 earset transmitter and AR2 receiver have USB inputs and can be charged using the included adapter or any 5-volt power supply.
