Hollyland Lark M2 Wireless Lavalier Microphones (USB-C) Review

We’ll be taking a quick look at the Hollyland Lark M2 compact wireless lavalier microphone. It’s an update to their popular Lark C1 microphone which we reviewed last year, and I have to say … it’s the most compact wireless lavalier microphone we’ve ever used. It’s designed for audio recording on your iPhone 15 or Android phones, and even action cameras and computers with a USB-C connector. It offers wireless audio transmission of up to 1,000ft line-of-sight range. It’s perfect for filmmakers, vloggers, and podcasters.

With optimized power efficiency, each microphone can work for up to 10 hours (with ENC off), and offers a total battery life of up to 40 hours when used with the included batery case. The compact charging case can fully charge the entire set twice, and each charge takes less than 1.5 hours.

The LARK M2 supports one-click on the yellow button to turn on/off the noise cancellation on TX and RX.  The enhanced firmware and audio algorithms ensure crystal-clear, rich, and undistorted human voices, even in noisy environments.

Featuring a sample rate of a 48kHz and a 24bit audio recording format, you can capture every sound with accuracy. It also has a 70dB signal-to-noise ratio, to ensures excellent audio signals with minimal background noise. Moreover, it can handle a maximum 115dB Sound Pressure Level, perfect for recording in environments with high-pitched sounds.

The Box and Packaging

Inside the box, you’ll find a USB-C charging cable, 2 dead-cats or wind-shield, 2 magnetic clips, a sticker sheet, a carry pouch and a charging case.

 

A Closer Look

Inside the charging case, you’ll find 2 wireless transmitters and 1 receiver with a USB-C connector (or iPhone 15 or Android phones).

The transmitter is absolutely TINY … which is great, if want to discreetly hide your microphone while wearing it on your shirt. You also have option to magnetically attach it via the included clips or lanyard.

 

Lark M2 in Action

Using the software, you can enable noise cancellation (weak or strong) and also the most important feature in my opinion … the recording Volume. You can set it to Low, Medium or High.

 

LarkSound App

I love the Speaker Play option. When enabled, it allows you to get real-time audio playback on your phone’s speaker without the need to unplug the receiver.

 

Conclusion and Verdict

Using your smartphone to produce video shorts or reels for Intsagram and Tiktok, is getting extremely popular. Especially when you have all the tools you need in the palm of your hand. But nothing is worse than recording a video clip with bad audio or muffled speech, thanks to the phone’s inadequate internal microphone.

Luckily, the Hollyland comes to the rescue with the Lark M2, which completely resolves this issue. It’s a super compact, button-sized wireless lavalier microphone designed for smartphones, such as the iPhone 15 or Android phones which uses the USB-C connector.

The microphone offers a sample rate of a 48kHz and 24bit audio recording, with a range of up to 1000ft. Each transmitter weighs in at only 9g. How anyone can fit this amount of technology in to a button-size module is beyond me and completely mind-blowing!

You can record 10 hours of audio with each microphone, and if you used the included charging case, you can get a total of up to 40 hours of battery life.

The speaker play option on the app, allows me to listen and playback the audio in real-time through the phone’s speaker, without the need to unplug the receiver.

The Hollyland Lark M2 is an incredible piece of kit, and I highly recommend it for vloggers, podcasters, filmmakers, and anyone who wants to record professional audio for their videos on their smartphone.
