HollylandLARK M3 Combo 2TX/4RX USB-C Wireless Microphone Kit – Space Gray

The Hollyland LARK M3 2TX/4RX Combo Kit is a compact wireless microphone system for smartphone vlogging, interviews and mobile filmmaking. This Space Grey 2TX/4RX package pairs two transmitters with a USB-C receiver, making it a practical option for recording two speakers on a compatible device.

Capture dialogue with AI noise cancellation and customise each voice using vocal presets and app-based fine-tuning. The lightweight transmitters help keep your setup discreet, whether you are filming a travel diary or sitting down for an interview.

This Kit: 2 Transmitters and 1 USB-C Receiver

This listing is for the 2TX/4RX USB-C configuration (6303-21). The wider LARK M3 system supports setups with up to four transmitters and four receivers. Expanded setups require additional compatible equipment; those system capabilities do not describe the contents of this package.

Detailed Wireless Audio

The LARK M3 offers 48 kHz / 32-bit float audio output, a 70 dB signal-to-noise ratio and a maximum sound pressure level of 125 dB. Hollyland's HDT wireless transmission technology supports wireless dialogue capture for on-location recording.

AI Noise Cancellation

AI-powered noise reduction helps suppress distracting background sounds, including traffic, wind and air-conditioning hum, so speech is easier to follow when recording outside a quiet studio.

Custom Voice Tuning

Adjust the sound for different speakers with one-tap vocal enhancement, eight built-in vocal presets and app-based fine-tuning. Each transmitter can use its own independent vocal preset.

One Tap Vocal Enhancement

Improve speech clarity with one-tap vocal enhancement featuring de-essing to help control harsh sibilant sounds. Designed for multi-person interviews, commercial shoots and everyday video recording, this feature helps keep voices balanced and comfortable to listen to, making dialogue easier to follow across a range of content formats.

Vocal Presets & Advanced Fine-Tuning

Choose from eight built-in vocal presets to suit different voices and recording scenarios, then fine-tune the settings in the companion app to create your preferred sound. Compare enhanced audio with the original recording to make quick, informed adjustments to your vocal profile. Each transmitter supports its own independent vocal preset, allowing up to four transmitters to use four different presets simultaneously. This makes the LARK M3 a flexible wireless microphone solution for interviews, podcasts, group videos and multi-speaker productions where each voice may require a different treatment.

Lightweight 9g Transmitters

Each button-sized transmitter weighs 9 g, helping minimise fabric pulling and visible microphone bulk during longer recording sessions.

Expandable Four-Track Recording

The LARK M3 system supports four independent audio tracks with the hot shoe adapter, or through compatible third-party software when a receiver is connected to a computer by USB-C. Recording four speakers requires additional transmitters beyond the two supplied in this kit. The hot shoe adapter is not confirmed as part of this package.

Wireless Range up to 300 m

The advertised transmission range is up to 300 m (1,000 ft) under suitable conditions. Obstacles, wireless interference and the recording environment can reduce usable range.

The illustration shows receiver options across the range, not the contents of this 2TX/4RX USB-C kit.

Control for Expanded Multi-Receiver Setups

When using multiple receivers, the system assigns Primary and Secondary Receiver roles. The Primary Receiver controls transmitter settings, including noise cancellation and mute, while Secondary Receivers monitor status. Additional receivers are required for this workflow.

Up to 8 Hours per Transmitter

Each transmitter provides up to eight hours of operation on a single charge. Combined runtime figures depend on charging and alternating transmitters; they do not represent continuous battery life from one microphone.

The illustration shows the wider system and a combined-runtime claim. It is not a packing list or a claim of 48 hours of continuous operation from one transmitter.
