Hollyland LARK M3 Combo 2TX+1RX Wireless Microphone (Space Grey)

Two voices into one device

The two transmitters send both speakers’ voices to the included USB-C receiver, so an interviewer and subject can each wear their own microphone while the phone, tablet or computer receives the audio through a single connection. When the USB-C receiver connects to a computer running compatible recording software, the two transmitters can also be captured as separate audio tracks, so each speaker’s level can be adjusted independently during editing. Each transmitter uses an omnidirectional capsule, so it picks up speech as the wearer turns their head rather than requiring the microphone to point directly at their mouth. The magnetic mounting system also means the 9g transmitter adds relatively little weight to clothing and reduces pulling on the fabric.

More headroom for changing voices

The LARK M3 outputs audio at up to 48kHz/32-bit float when the connected device and recording application support it. That format gives compatible software more room to accommodate large changes between quieter speech and stronger peaks during recording and post-production. The microphones handle up to 125dB SPL, while the signal-to-noise ratio of at least 70dB keeps speech separated from the system noise floor. Auto-Limit Clip Protection also manages sudden level jumps, automatically reducing excessive peaks before they overload the recording level. Android currently outputs up to 24-bit, while Apple devices require compatible third-party recording software for 32-bit float.

Noise reduction you can set to the location

AI Noise Cancellation offers three strengths: 10dB, 15dB, and 20dB. A stronger level reduces background sounds such as traffic, wind, running water, or air-conditioning, while a lighter setting applies less processing when the surroundings are quieter. You can switch Noise Cancellation on/off from either transmitter or the USB-C receiver, so you can change the setting without reaching for your phone.

Tune each speaker separately

Through the HollyAudio app, each transmitter can use its own saved voice profile, so two people with different voices do not have to share the same processing. Built-in vocal presets provide starting points, then you can adjust the effect and save it for later use. One-Tap Vocal Enhancement takes a simpler approach by applying the same processing to both transmitters and reducing vocal sibilance across the pair. The USB-C receiver also provides six levels of gain adjustment through the app, changing the level sent to the connected device.

Eight-hour battery and direct USB-C connection

Each transmitter runs for approximately eight hours, providing enough operating time for interviews, presentations and longer recording sessions without frequent charging. In open, unobstructed conditions, the 2.4GHz wireless link reaches up to 300m, while adaptive frequency hopping shifts between available frequencies to maintain the connection as radio conditions change. The USB-C receiver plugs directly into compatible devices and includes a second USB-C port, so a phone can stay connected to external power while recording.
