Hollyland LARK M2S Wireless Lavalier Microphone System

The Hollyland LARK M2S pairs two 7 g wireless transmitters with receivers for cameras and phones and a charging case. Each transmitter has a titanium clip and no logo on the front.

Discreet Transmitters

The front of each transmitter measures 13 x 6.3 mm, so it sits small on a collar, and the titanium clip holds it in place through fast movement. A furry windshield comes with each transmitter for outdoor recording.

Sound and Noise Cancellation

The transmitters record at 48 kHz/24-bit with a signal-to-noise ratio above 70 dB and a maximum sound pressure level of 116 dB. One press of the noise cancellation button on a transmitter or receiver turns on ENC, which removes low-frequency noise, and the LarkSound app sets it to Strong or Weak.

The link reaches up to 1,000 feet (300 m) line of sight over 2.4 GHz adaptive frequency hopping. A circuit built to resist RF interference keeps the audio clean in office buildings, venues, and city streets.

Receivers and Power

The camera receiver has a 3.5 mm TRS output and a USB-C port, which can feed two recorders at once through an adapter cable. Its knob sets the volume, shown on LEDs, and switches mono or stereo. The USB-C and Lightning receivers plug into a phone and accept a charging cable that charges the phone. A setting in the app plays recordings back through the phone without unplugging the receiver.

Each transmitter runs about 9 hours and the camera receiver about 8.5 hours. The charging case brings the total to about 30 hours with a combo kit, or 27 hours with the Duo, and recharges the set in under 1.5 hours. The set comes paired from the factory. The Configurations tab compares the four kits.
