When people start learning about wireless microphone systems, they're sometimes surprised to find out that multiple components are needed: a microphone, a transmitter and a receiver. Samson's AirLine 77 headworn systems have a small transmitter built into the headset, so it seems like there are only two components involved, instead of three.
The AH1 Headworn Transmitter is a great option for fitness instructors and live performers because you don't have to attach a beltpack transmitter to your body when you use it. One of the big drawbacks of a beltpack-based headset system is that a wire needs to run from the beltpack up to the headset. This isn't an issue with the AH1.
There are two different kinds of AH1 transmitters available. They both feature the same basic integrated transmitter design. The trait that makes them different is the microphone element. One AH1 headset model features the QV10e microphone, the other features the Qe microphone.
The QV10e microphone element is a better choice for singers and musicians because the frequency response of the microphone is simply better suited for music. The Qe microphone element is a better choice for fitness instructors and public speakers since the frequency response of the Qe microphone capsule is better suited for speech.

Both microphones have a cardioid pick-up pattern, which make them a good choice for use with live sound systems. A cardioid pick-up pattern will help reduce feedback by rejecting sound from in front of and to the sides of the mic. Both microphones were also designed to be moisture resistant, which makes them well suited for use on stage and in the gym.
A five pack of replacement windscreens is available that's compatible with both the QV10e and the Qe microphones. They come in multiple colors, which is especially useful if more than one person uses a headset. This way one person can be assigned to use a specific colored windscreen, for a more sanitary working environment. The colors can also help live acts add some flare to their stage presence.
These systems are available in six different frequencies, channels N1 through N6. They operate in the UHF range, which is more reliable than VHF and completely in line with the recently revised FCC standards. If you plan on using more than one AirLine system, you should be mindful that you buy each system on a separate channel so they don't interfere with one another.
