The WM820 by Maono is a wireless condenser microphone system consisting of dual transmitters with built-in lavaliers and a receiver.

Pricing-wise, the company still hasn't revealed how much this model will cost. However, I doubt it will be costlier than half of our top podcasting mic picks.

Compatible with Android, macOS, and Windows devices, this omnidirectional mic is designed for 21st-century content creators, hosts, and educators.

Features, Accessories, and Quality

Let’s go over the technologies behind the WM820 and how good its audio output is.

Omnidirectional Pattern

Because of its omnidirectional polar pattern, it can pick up sound from all directions.

Due to its heightened acoustic sensitivity, the WM820 is perfect for studio recordings where the source of sound is wide.

If recording uninterrupted natural sounds is your goal, this equipment will fit the bill.

In contrast, some of the best streaming mics that we’ve checked were optimized for multiple polar patterns. Besides the omnidirectional pattern, the likes of Blue Yeti Nano and EPOS B20 also support cardioid, bidirectional, and/or figure-8.

Clear Audio

This product is a condenser mic system. Unlike dynamic mics that are suitable for loud noises, condenser ones can accurately pick up the intricacies of delicate sounds.

Moreover, this model has a professional audio chip and uses MNCT denoise tech. Its frequency response ranges 50Hz–18kHz. And its Total Harmonic Distortion Plus Noise (THD+N) ratio is 0.4%. As far as the signal-to-noise (S/N) ratio is concerned, it boasts an excellent 82dB.

Technical talk aside, the WM820 can capture every little audio detail clearly.

Wireless Transmission

The WM820 is a wireless device that operates on the industry-standard 2.4 GHz band. In other words, it has no annoying cords that can cause a host of limitations to your production.

Apart from presenting zero tripping hazards, wireless microphone systems like this one naturally offer better ease of movement. Plus, you can use this model discreetly.

Arguably, wireless mics can outlast their wired counterparts, for cables are prone to damage. As long as you take good care of its transmitters and receiver, the WM820 should function properly for a long time.

Extensive Transmission Distance

In an open area, it can send audio signals with ultra-low latency from up to 115 feet. Testing the Maono wireless mic for this review confirmed it – you can enjoy great mobility without getting disconnected.

If you’re in a virtual meeting or an online class, it won’t keep you tied to your computer or mobile device. You can keep talking while walking far away from the receiver without fear of sounding choppy at any point.

Dual Transmitters

The WM820 has a pair of transmitters with built-in mics. You can clip either of them onto your clothing, so you can create content hands-free.  

Unlike its sibling device, the PM500T, this one is ideal for two-person vlogs and interviews. In playback, each speaker would sound as clear as the other – a key recipe for engaging conversations.

Furthermore, the WM820’s transmitters support external lapel mics for added flexibility and audio control.

Built-In Lavalier Mics

Each of the WM820’s transmitters comes with a lav. That’s why this mic system is compact, portable, and lightweight.

Although this device can record audio coming at 360°, it’s still suitable for outdoors. Despite the background noise, its close proximity to the speaker enables it to capture clean speech when worn correctly.

Since the WM820 is a two-mic unit, it offsets the biggest drawback of lavaliers: recording audio from multiple speakers. It lets two people speak simultaneously while moving around without sacrificing audio quality.

Admittedly, lav mics don’t look as good as shotgun ones in front of a camera. But it should be less of an issue in projects or activities where audio is more important than video.

However, if you are more comfortable with a lavalier mic, each box comes with two for each transmitter.

Inside the box is a trio of foam windbreaks, which can eliminate the distracting noise common in outdoor shoots.

These handy accessories can stick out like a sore thumb and become a bit distracting. Nevertheless, they make it possible to produce quality content even when the winds are strong.

Automatic Pairing

You can link the WM820’s transmitters to the receiver with a click of a button. If all goes well, the pairing process will take two seconds tops. So, you should be able to get this equipment up and running in no time.


Using the WM820, you can silence yourself with one click and let other speakers have the floor.

Doing that can spare you some uncomfortable moments. Have you ever realized you’ve been live after talking about personal stuff for the past ten minutes?

Well, thanks to WM820, you have full control over your audio.

Long Battery Life

One of the biggest takeaways from this Maono WM820 review is the product’s six-hour battery life. Its transmitters have 350mAh rechargeable batteries.

To give them some juice, hook them up to a charger or an active device with a USB-C port for 120 minutes. A splitter cable is part of the package, so you can charge both transmitters at the same time.

Plug-and-Play Receiver

The WM820 doesn’t rely on external power. Just plug it directly into the USB-C port of your desktop or mobile device to power it and begin recording. It’s compatible with Android, macOS, and Windows devices.

Since this model doesn’t have a lightning connector, you can’t use it on the iPhone, iPad, and/or iPod. If you need a mic that’s compatible with iOS and iPadOS, go with the WM820’s B2 version instead.


The WM820 did produce clear audio even in outdoor settings. Its foam windbreaks significantly minimized the wind noise caused by breezes. And its built-in mics were able to capture crisper sounds than external lavaliers.

Nevertheless, this condenser mic system shines the most in places with good acoustics. Just find a quiet spot, and you can record high-quality tracks, voice-overs, and live streams. Your digital recordings should need little to no enhancements.

However, the goal of this Maono wireless mic review is objectivity. So, here are some of the problems I noticed:

Closely resembling the B2 version, the WM820 has no gain and volume controls. With no means to adjust these levels, you ought to be mindful of your voice’s loudness. Overly amplified audio signals could result in unwanted popping or cracking sounds. This could happen even if you’re speaking at a normal volume, which can be frustrating.

The mic also lacks visual indicator of when the audio is clipping. 

Pairing the WM820’s transmitters and receiver may not always go smoothly. You may have to attempt it multiple times to get both of them to work.

Tips on How To Use the WM820 to Maximum Effect

To make the most out of this wireless mic system, consider the following pieces of advice:

Think About Obstructions

The WM820 has a fairly long transmission range. But obstructions like walls can shorten the distance its sound signals can travel. Being located multiple rooms or floors away from the receiver can unpair it from the transmitters without warning.

To ensure uninterrupted production, estimate your proximity to the receiver when you roam around.

Test Everything Before Recording

With limited indicators, it’s hard to tell whether this mic system can produce your desired audio quality without testing. The last thing you want is to discover disappointing output after spending considerable time and energy creating content.

Rigorously doing test recordings is good practice. It can be a hassle when you want to produce something on the fly. However, it’s a small price to pay if you want to avoid wasting your efforts.

Keep Battery Life in Mind

Dealing with a low-bat wireless mic mid-recording can be a real pain. This holds particularly true when you’re doing live events like seminars, hosting gigs, and interviews.

To prevent this equipment from quitting on you at the worst possible time, always take note of its remaining battery life.


The WM820 is far from perfect.

It doesn’t share some of the controls its sibling mic systems have, limiting its functionality. Plus, its lack of digital recording capability makes its price less reasonable.

That said, there’s no denying its versatility.

Thanks to its built-in lapel mics, plug-and-play receiver, and relatively extensive transmission range, it’s workable in outdoor content creation. As a piece of omnidirectional equipment, it promises an incredible performance for indoor audio recording sessions.

As evidenced by this Maono WM820 review, it’s not the most affordable out there, nor is it the most capable. But it can still be a good addition to your recording gear.
