48 kHz/24-bit High Fidelity Audio
LARK M2 offers 24-bit depth for capturing nuanced sound details. With a high signal-to-noise ratio (SNR) of 70 dB, LARK M2 can produce clearer, polished recordings with a low noise floor. Capable of handling sound pressure levels up to 115 dB, LARK M2 excels in capturing audio in various environments.
Incredibly Small
At only 9g, the transmitter (TX) is small enough to stay securely fastened to your clothing without any drooping or sagging. Its button-size design is practical, convenient and doesn't compromise audio quality.
Precise Noise CancellationCaptureYour True Sound
LARK M2 uses Environmental Noise Cancellation (ENC) technology to precisely minimize noise across frequencies, preserving original voices with crystal clear clarity and full-toned richness.
300m (1,000ft) Stable Transmission
LARK M2 is equipped with an advanced high-gain Laser Direct Structuring (LDS) antenna for stable audio transmission, free from human body interference. With an impressive range of up to 300m (1000ft)[2], capturing your voice loud and clear in challenging, long-distance recording environments is not hard anymore.
40 Hours Long Battery Life
