Hollyland LARK M2 Wireless Lavalier Microphone System

The Hollyland LARK M2 pairs two button-size 9 g wireless transmitters with a receiver for a camera, phone, or computer, and a case that charges and carries the set.

Receivers and Versions

The camera receiver has a 3.5 mm output, a volume knob with three LEDs, and a button that switches between mono and stereo when it is connected to a camera. The mobile receivers plug straight into a phone or tablet: a Lightning plug with an MFi-certified Apple chip, or a USB-C plug for USB-C phones, action cameras, and computers. The Combo carries the camera receiver and both plug-in receivers. The Configurations tab compares the four kits and their colors.

Each transmitter attaches with a magnet or hangs from its silicone necklace case, and the set comes paired from the factory. The receivers support UAC, so they connect to a computer with no external sound card.

Range and Band

Over 2.4 GHz adaptive frequency hopping, the link reaches up to 1,000 feet (300 m) line of sight. A high-gain antenna keeps the signal steady when the wearer’s body is in the way, and a metal mesh over the mic guards against dust and interference.

Sound and Power

The transmitters record at 48 kHz/24-bit with a signal-to-noise ratio above 70 dB and handle sound pressure levels up to 115 dB, and ENC reduces the noise around the speaker.

A transmitter runs about 10 hours on a charge. The camera version’s case gives about 40 hours of total use and recharges in under 2 hours, and the mobile versions’ case gives about 30 hours and recharges in under 1.5 hours.

App and Phone Control

The LarkSound app updates firmware, sets volume and noise cancellation, and shows audio status. With a plug-in receiver on a phone, recordings play back through the phone’s speaker without unplugging. On phones where one press of a volume button starts video or takes a photo, a double press of the transmitter’s noise cancellation button does the same.
