Expert Features

• Invisible No-Logo Wear : The LARK M2S uses a discreet logo-free microphone body that stays visually subtle on clothing, keeping attention on the creator rather than the microphone.
• Titanium Clip-On Design : Its innovative titanium clip combines low weight with strong structural stability, helping the microphone stay securely attached even during active movement.
• Featherweight 7g Transmitter : Each transmitter weighs only approximately 7g, minimizing fabric pull, sagging, and discomfort during long interviews, reels, livestreams, classes, or mobile shooting sessions.
• 48kHz / 24-bit Recording : Captures audio at 48kHz / 24-bit, preserving vocal detail and giving creators cleaner, more natural recordings than basic mobile-mic solutions.
• 70dB+ Signal-to-Noise Ratio : With an SNR greater than 70dB, the LARK M2S keeps background electronic noise low so speech stays clearer and more defined.
• 116dB SPL Handling : Handles sound pressure levels up to 116dB SPL, giving the microphones useful headroom when recording energetic speakers and louder sources.
• Dual-Level ENC : Environmental Noise Cancellation suppresses low-frequency environmental noise, while the LarkSound App provides Strong and Weak cancellation levels for different recording environments.
• 300m Wireless Range : The USB-C Mobile Version reaches up to 300m / 1,000ft line-of-sight, with up to 60m / 200ft non-line-of-sight transmission under Hollyland’s stated test conditions.
• RF Interference-Resistant Circuit : Hollyland integrates a dedicated RF interference-resistant circuit plus 2.4GHz Adaptive Frequency Hopping, helping maintain stable audio in offices, streets, event venues, and other signal-heavy environments.
• 27-Hour Mobile Battery System : Each transmitter offers approximately 9 hours of operation, while the USB Type-C Version’s mobile charging case extends total use to approximately 27 hours.
• Fast Mobile Charging Case : The 680mAh Mobile Version Charging Case can recharge both transmitters together more than twice and itself charges in less than 1.5 hours.
• USB-C Plug & Play : Connect the compact USB-C receiver directly to a compatible USB-C mobile device—no complicated pairing procedure or audio cable is required.
• Playback Without Unplugging : Compatible phones can play back recorded clips without removing the USB-C receiver, allowing an immediate audio-quality check after recording.
• Charge Your Phone While Recording : The receiver’s USB-C charging port can accept a charging cable while connected to a smartphone, helping keep the phone powered during extended recording sessions.
• Pre-Paired Out of the Box : The two transmitters and receiver automatically pair after initial setup, getting creators from case to recording in seconds.
• LarkSound App Control : Monitor battery level, volume information, VU-meter activity, noise-cancellation level, and perform firmware updates directly through the mobile app.
