Hollyland LARK 150 Duo Wireless Microphone

Worried about collar turning down? The coin-sized mic weights only 20.5g, equivalent to the weight of a walnut, allowing it to work as a piece of jewelry and be almost invisible on people when clipped to the collar.
Sounds cutting out during yoga, jogging, and other workouts?
The built-in floating buffer sponge effectively avoids collision between the mic and the shell during exercises to reduce noise and enable delicate sound collection.
One for all is true. Your voices can be recorded regardless of the shooting equipment. Mobile phones, cameras, sports cameras, tablets, computers, etc., all can be used together with it.
Note: It needs an adapter cable from Hollyland to work with mobile devices.
It scans the surrounding frequency 8,000 times per second and automatically connects to the interference-free channel to ensure the system is always connected. All sounds can be received with no dropouts, even when shooting in the busy streets.
It enables ultra-low latency sub-5ms response at up to 300ft(100m) transmission distance. The range of activities is no longer limited. Take the camera or mobile devices to jump, run, and shout. As long as you are there, the sound is there.
