Move Free
Samson revolutionized wireless with the original AirLine transmitter. Building on this groundbreaking technology, the AH7 Micro Transmitter is mounted directly on the headset. This is unique compared to traditional wireless systems that typically use a belt pack with a wire running from the microphone to the transmitter. The AH7 eliminates these extra components, which can be particularly cumbersome for a fitness instructor, and puts everything you need neatly and comfortably around your head. The transmitter runs for up to eight hours on a single AAA battery.

The Right Mic for Fitness
The AH7 headset transmitter is mounted on a lightweight, adjustable headset that fits comfortably around your ears and the back of your head, even on those days when you're teaching back-to-back classes for hours. The headset also features the Samson Qe condenser microphone, whose sweat-resistant capsule prevents corrosion from prolonged exposure to moisture. In addition, the microphone's bi-directional pickup pattern reduces background noise, minimizes feedback issues, and effectively rejects signals not directly in front of the microphone capsule.
