Lark M1 wireless lavalier mic is super compact and lightweight, only 0.42oz and 0.4″ in thickness. Designed with a built-in clip, it can be easily snapped on virtually collars. With a flat and sleek design, it’s even smaller than a USB flash drive. It feel like nothing on your collar but a photogenic item.

8h Long Battery Life, Fast Charging

The Lark M1 micriphone can work up to 8 hours after a full charge. In full capacity, the charging case can charge the whole set twice, and keep them working up to 20h. It takes only 1.5h to charge the TX/RX. After a short break, the device will be fully powered again.

650ft Long Transmission

Lark M1 lapel microphone’s transmission distance is up to 656ft and the delay is less than 0.08s. Automatic frequency switching when there is interference. Upgraded Bat Obstacle Avoidance 2.0 transmission technology optimizes the codec algorithm for the audio wireless baseband transmission protocol, and improves the stability of long-distance transmission by 90%.

HiFi Sound Quality, Rich Audio Details

Using LC3 codec + up to 48KHZ/16bit sampling rate to achieve a sound quality beyond CD level, Lark M1 records sound for you without loss and compression. Its high sound is transparent and undistorted, and its bass is thick and magnetic. Let’s make audio creation one step closer to art.

Auto Device Recognition

Ready to use out-of-the-box, no tedious setting. Lark M1 mic system will automatically identify the connected device (mobile phone or camera), select working modes, and adaptive volume settings. No manual adjustment is required.


  1. After the receiver and microphone are fully charged in the charging case, they will automatically stop charging. When the units have not been used for a long time, the battery power will be consumed little by little. But when the charging case cover is opened again, it will be activated to detect the power of the receiver and microphone and recharge the units.
  2. When the charging case is completely power off, it takes about 1.5 hours to fully charge a empty charging case without the TX/RX in it. When the charging case is fully charged, then it can charge 2 TX and RX twice.
  3. The receiver and microphone can be used while charging directly via USB Type-C port.
