The LARK 150 system is automatically paired, charged, and stored in the included charging case that charges all three units using its USB input port. The transmitters are small and lightweight at less than 1 oz, and they clip onto a lapel or shirt and feature a built-in omnidirectional microphone, and you can also use the included lavalier microphones with the 3.5mm input ports. They also both feature a two-way mute button and built-in clip. The receiver features volume buttons, a 3.5mm headphone monitoring output, a 3.5mm line output, and a display that shows the connection and battery status of all three units.

The transmitters feature an anti-vibration design with intelligent noise cancellation and smart frequency selection using FHSS (Frequency Hopping Spread Spectrum) technology for a crisp, clear signal using the 2.4 GHz bandwidth. You can transmit a strong signal with less than 5 ms latency at up to 328' away from the receiver. The system also supports switchable safety, stereo, and mono modes for different configurations. A USB cable, 3.5mm TRS audio cable, two furry windscreens for the lavalier mics, and a storage bag are also included with the system.
