About Samson AirLine Micro ESm

Designed as the perfect tool where convenient hands-free wireless audio is necessary, such as fitness instruction, house of worship, or presentations. The AirLine Micro ESm eliminates the hassle of wearing a beltpack by keeping the entire transmitter encased in an easy-to-wear rechargeable earset that fits securely and comfortably behind the ear. With frequency-agile operation using one-touch scan setup, the AirLine Micro ESm is ready for use in any RF environment. It is great for fitness, audio for video, work from home, theater/ production, house of worship, live sound.

The Mighty Micro
The AirLine Micro ESm combines a traditional beltpack and headset system into one discreet, rechargeable earset transmitter that fits behind the ear. The transmitter is moisture- and sweat-resistant, so it's ready for long performances in the spotlight or full fitness workouts. An omnidirectional microphone easily picks up your voice in a variety of positions, and the multifunction button serves as a one-touch mute, volume control, and power switch, giving the earset the full functionality of a traditional beltpack system in a fraction of the space.

Audio Over the Air
The AirLine Micro ESm uses frequency-agile UHF analog wireless technology to provide crisp, clear audio and avoid interference. The system's one-touch scan analyzes and selects the clearest operating channel available, ensuring the highest signal-to-noise ratio possible in any given space. With a working range of 300' (line-of-sight), the AirLine Micro ESm brings wireless freedom to any venue, stage, or presentation.

Easy Connectivity
The AR99m receiver has a full suite of connections to accommodate any audio setup. Equipped with XLR, 1/4", and 1/8" outputs, you can plug the AR99m into mixers, speakers, or other audio gear for easy integration and operation in any setup.
