Yealink Video Conferencing Microphones: Which One Does Your Room Actually Need?

Quick answer: For most Indian meeting rooms seating six to twelve people, the Yealink VCM35 tabletop array is the right starting point at Rs 39,825. Choose the VCM36-W wireless microphone if your tables move or you cannot run cable. Choose the CM20 AI ceiling microphone if the table must stay clear or the room is a boardroom or training room. Small huddle rooms usually need no separate microphone at all, because the video bar already has one. This guide explains how to tell which situation you are in.

First, do you even need a separate microphone?

This is the question most buyers skip, and it is the one that saves the most money.

Modern Yealink all-in-one video bars have microphone arrays built in. If your room is a huddle space or small meeting room seating four to six people around a short table, a video bar on its own is usually sufficient. The UVC34 all-in-one USB video bar or the MeetingBar A10 will pick up everyone in the room without help.

You need a separate or expansion microphone when one or more of these is true:

The table is longer than about three metres, so the far end sits outside the bar's reliable pickup range.

The room is L shaped, has an alcove, or seats people away from the main table.

The room has hard surfaces, glass walls or a high ceiling, which raise reverberation and hurt intelligibility at distance.

Remote participants regularly say "sorry, could you repeat that" when someone at the back speaks. This is the practical test, and it is more reliable than any specification sheet.

If none of these apply, buy the video bar and stop there. If any apply, read on.

Yealink expansion microphone explained

An expansion microphone extends voice pickup beyond what a video bar or codec captures on its own. It does not replace the built-in microphone. It works alongside it, effectively moving the listening point closer to the people who are furthest away.

Yealink's current expansion microphones are the wired VCM35 and the wireless VCM36-W. Both provide 360 degree omnidirectional pickup, both include acoustic echo cancellation and noise suppression, and both are designed to sit on the meeting table rather than in the ceiling.

Important: the VCM34 has been discontinued

If you are comparing older buying guides or reseller listings, you will still see the Yealink VCM34 recommended. It was discontinued on 31 January 2024, and Yealink's own recommended replacement is the VCM35.

This matters for two practical reasons:

New purchases should specify VCM35. Buying end of life stock leaves you without a supply path for replacements or additions later.

Existing VCM34 fleets still work. If you already own VCM34 units, they continue to function with compatible systems. The Yealink AVHub processor supports up to eight VCM34 or VCM38 array microphones, so mixed estates are manageable. Plan replacement at refresh, not immediately.

Anyone still quoting you VCM34 for a new project in 2026 is working from an outdated price list. That is a useful signal when comparing suppliers.

"Yealink mini microphone": what buyers usually mean

Yealink does not sell a product literally named "mini microphone", so this search term maps to one of three different needs. Identifying which one you have prevents an expensive mistake.

If you are unsure which of these describes your room, our team can advise before you order. Talk to us.

Choosing by room size

This is the most reliable way to specify audio, because pickup range is a physical constraint and no amount of processing overcomes a microphone that is simply too far away.

How to work out the number of microphones

Take the length of the seating area in metres and divide by the effective pickup radius, then round up.

A VCM35 covers roughly 5 m radius under good acoustic conditions. A 7 m boardroom table therefore needs two units, one positioned at roughly one quarter and one at three quarters along the table. A single unit in the centre leaves both ends marginal.

Reduce your assumed pickup radius by 20 to 30 percent in rooms with glass walls, bare concrete or exposed ceilings. Reverberation shortens usable range considerably, and it is the single most common reason a specification that looked fine on paper disappoints in the room.

Tabletop versus ceiling: an honest comparison

Our practical view after delivering 250 plus AV projects: ceiling microphones are worth the premium in boardrooms, client facing spaces and rooms where furniture is fixed. In everything else, a well positioned tabletop array delivers comparable intelligibility for a third of the cost. Do not pay for ceiling audio to solve a problem that a second VCM35 solves.

Wired VCM35 or wireless VCM36-W?

Both are Rs 39,825, so price is not the deciding factor. These are:

Choose the VCM35 (wired) when:

The table position is fixed and cable routing is available, ideally through a table grommet or floor box.

The room is in continuous daily use and nobody wants to think about charge levels.

You may want to cascade additional units later. The VCM35 supports star cascaded deployment for larger rooms.

Choose the VCM36-W (wireless) when:

Tables get reconfigured for different meeting formats.

You are retrofitting a room where new cabling is impractical or expensive.

You want a clean table with no visible cable runs.

Meetings run under 11 hours, which is the rated talk time, with 70 hours standby. Up to four units can be paired for larger rooms, and the unit uses WPA2 and AES128 encryption over WiFi.

The realistic risk with wireless is procedural, not technical. Someone has to put it back on the charging dock. Rooms without a clear owner tend to find the mic flat at 9 am. If your facilities process is informal, wired is the safer specification.

Larger and more complex rooms: AVHub and RCH40

Once you go beyond two or three microphones, or you are combining multiple cameras with multiple audio zones, you need a processor rather than a longer daisy chain.

The Yealink AVHub at Rs 2,40,720 is the aggregation point for large and divisible rooms. Its published capacity is:

• Up to 8 VCM34 or VCM38 array microphones

• Up to 4 MSpeaker II units

• Up to 4 CM20 or CS10 devices

• Up to 9 UVC84 or UVC86 cameras

• USB-B, codec, 7x VCH RJ-45, RCA in and out, and 6.3 mm line in and out

For simpler multi device rooms, the Yealink RCH40 at Rs 26,550 provides a four port PoE switch designed for meeting room devices. It is the tidy way to power ceiling microphones and cameras without dragging room devices onto the corporate network switch, which also simplifies the conversation with your IT team.

Platform compatibility

All the microphones covered here work with Microsoft Teams Rooms, Zoom Rooms and Google Meet when paired with a compatible Yealink system.

A point worth understanding: certification applies to the system, not usually to the microphone in isolation. A Teams certified room is certified as a bundle of codec, camera and audio. If your organisation requires certified hardware for compliance reasons, specify a certified room system such as the MVC S40 Microsoft Teams Rooms system rather than assembling components and assuming the result inherits certification.

If you are running BYOD or a mixed platform estate, tell us at the design stage. It changes the specification meaningfully. Our solutions overview covers how we handle multi platform corporate deployments.

Five specification mistakes we see repeatedly

Buying microphones before measuring the room. Pickup range is physics. Specify from a floor plan and a tape measure, not a brochure.

Ignoring the acoustics. Glass walled meeting rooms are common in Indian offices and they are acoustically hostile. Budget for basic treatment or accept that you will need more microphones.

Treating the microphone as an afterthought. Remote participants forgive mediocre video far more readily than they forgive poor audio. If budget is tight, cut camera specification before audio.

Forgetting the return path. A microphone captures the room. It does not solve remote participants being inaudible in the room. Check your speaker specification too, and consider the MSpeaker II soundbar.

No cable management plan. A wired microphone with three metres of cable across the table looks worse than no microphone at all. Specify grommets and floor boxes at design stage.

Frequently asked questions

Which Yealink microphone is best for a conference room? 

For rooms seating six to twelve, the VCM35 is the default recommendation. Rooms with movable furniture suit the VCM36-W wireless unit. Boardrooms and rooms requiring a clear table suit the CM20 ceiling microphone.

What is a Yealink expansion microphone? 

An expansion microphone extends voice pickup beyond a video bar's built-in array. The VCM35 and VCM36-W both act as expansion microphones, adding 360 degree pickup at the far end of longer tables while working alongside the bar's own microphone.

Is the Yealink VCM34 still available? 

No. It was discontinued on 31 January 2024, with the VCM35 as the recommended replacement. Existing VCM34 units continue to work, and the AVHub processor supports up to eight VCM34 or VCM38 microphones, so mixed estates remain viable.

How far does a Yealink microphone pick up? 

The VCM35 array covers approximately 5 m and the VCM36-W approximately 6 m, both at 360 degrees. Treat these as ideal condition figures and reduce your working assumption in acoustically hard rooms.

Can I use more than one Yealink microphone in a room? 

Yes. The VCM35 supports star cascaded deployment, up to four VCM36-W units can be paired, and the CMKit-121 supports up to four CPW90 wireless microphones. Larger configurations are managed through the AVHub processor.

Does the Yealink VCM35 work with Zoom and Microsoft Teams? 

Yes. It works with Microsoft Teams, Zoom, Google Meet and Yealink conferencing systems, connecting over USB with plug and play setup.

How much does a Yealink conference microphone cost in India? 

Tabletop models start at Rs 39,825. Ceiling microphones start at Rs 1,23,900 for the CM20, and complete ceiling audio kits are Rs 2,53,110 for the CMKit-121. Installation, cabling and commissioning are quoted separately for ceiling deployments.

Do ceiling microphones need special cabling? 

Yes. They are powered over Ethernet and require a cable run to the ceiling position plus a PoE source such as the RCH40. Factor in ceiling access and installation time, particularly in occupied offices.

What warranty do Yealink microphones carry? 

The Yealink products in our catalogue include a two year hardware warranty. We provide installation, user training and ongoing after sales support alongside it.

Should I buy a room kit or individual components? 

If you need platform certification or want a single point of support, buy the room system. If you are extending an existing room, buy the expansion microphone. Our guide to video conferencing solutions and services covers this decision in detail.
