Yealink CPW90 Wireless Expansion Microphone for CP960 — Expand Your Conference Room Audio to Every Corner of the Room

Every voice deserves to be heard.

In the modern workplace, the conference call has become the cornerstone of business collaboration — the moment where strategy is set, decisions are made, clients are won, and teams are aligned. Yet for millions of professionals worldwide, that critical moment is undermined daily by a single, frustratingly common problem: the person at the end of the table who can’t be heard clearly. The executive whose input is lost in room echo. The remote participant who keeps asking for repetition. The critical point that gets missed because the microphone simply couldn’t reach far enough.

The Yealink CPW90 Wireless Expansion Microphone eliminates that problem entirely. Engineered as the perfect companion to the Yealink CP960 conference phone, the CPW90 extends premium HD audio capture to every seat at every table — regardless of room size, table configuration, or the number of participants — delivering the crystal-clear, omnidirectional voice pickup that transforms a frustrating conference call into a genuinely productive business conversation.

This is not a peripheral accessory. The Yealink CPW90 is a mission-critical audio extension that completes the CP960’s conference room coverage, ensuring that no voice goes unheard, no contribution goes uncaptured, and no meeting is diminished by the limitations of microphone reach.

Why Conference Room Audio Coverage Is the Most Underestimated Factor in Meeting Productivity

Research consistently demonstrates that audio quality is the single most cited complaint in enterprise video and voice conferencing — ahead of video quality, connection stability, and software usability. When participants cannot be heard clearly, meetings become exercises in repetition, frustration, and miscommunication that erode both productivity and professional relationships.

The root cause is almost always physical: a single conference phone — however technically capable — has a finite microphone pickup radius. In small meeting rooms with four to six participants seated close to the device, that radius is sufficient. But in medium and large conference rooms, boardrooms, training rooms, and open collaboration spaces where participants are spread across long tables or wide seating arrangements, a single microphone unit inevitably leaves participants at the periphery underserved.

The Yealink CPW90 was designed as the precise solution to this precise problem. By adding one or two wireless expansion microphones to a CP960 deployment, the effective audio capture zone of the conference system expands dramatically — covering the full length of the conference table, reaching participants seated against walls, and capturing clear voice audio from every seat in the room without a single additional cable on the table.

The result is a conference room where everyone sounds as though they are seated directly in front of the microphone — and that changes the entire quality of the meeting.

Who Needs the Yealink CPW90?

Medium to Large Conference Rooms

The CPW90’s primary application is the medium to large conference room where a single CP960 unit at the centre of a long table cannot provide adequate microphone coverage to participants at the far ends. A standard conference room table of 4 metres or longer, or a boardroom seating 10 or more participants, almost always requires microphone extension to ensure that every participant’s voice is captured with equal clarity. One or two CPW90 units positioned along the table extend the CP960’s coverage zone to encompass the full table length — giving every participant equal audio presence in the call.

Boardrooms & Executive Meeting Spaces

In boardroom environments where every executive voice carries strategic weight, audio quality is non-negotiable. The CPW90 ensures that the chairperson at the head of the table, the CFO at the far end, and every participant along the sides are captured with identical HD audio clarity — eliminating the hierarchy of microphone proximity that forces some participants to speak louder or lean awkwardly toward a central device to be heard.

Training Rooms & Workshop Spaces

Training environments frequently involve participants seated in configurations — U-shapes, classroom rows, or cluster arrangements — where a single central microphone cannot achieve adequate coverage of all speakers. The CPW90’s wireless flexibility allows it to be positioned independently of the CP960 in whatever location best complements the room layout — placed in the centre of a U-shaped arrangement, positioned at the back of a classroom configuration, or moved between cluster groups as training activities require.

Huddle Rooms & Open Collaboration Spaces

Modern open-plan offices increasingly feature informal huddle spaces and collaboration zones where impromptu meetings occur in non-traditional layouts. The CPW90’s compact, wireless design makes it ideal for flexible deployment in non-fixed meeting environments — bring it to any table, any space, pair it with the CP960, and the conference system’s audio coverage immediately expands to cover the collaborative group, regardless of their configuration.

Legal, Financial & Professional Services Firms

In professional services environments where every word spoken on a conference call may carry contractual, legal, or fiduciary significance, the precision and completeness of audio capture is a professional obligation as well as a practical requirement. The CPW90 ensures that no participant’s contribution is missed or inaudible — and when paired with the CP960’s call recording capability, ensures that complete, high-quality recordings of important calls are available for review and compliance purposes.

Educational Institutions & Lecture Theatres

For universities, colleges, and training institutions conducting remote or hybrid lectures and seminars via conferencing platforms, the CPW90 enables faculty and student voices to be captured from across large lecture spaces — ensuring that remote participants receive the same quality of audio as those physically present, and that question-and-answer sessions are fully captured from audience members seated at a distance from the primary CP960 unit.

Solving Your Most Critical Conference Audio Challenges

❓ “Participants at the ends of our conference table can’t be heard clearly on calls — how does the CPW90 fix this?”

This is the most common conference room audio problem in business — and the CPW90 is its direct solution. Position one CPW90 at each end of your conference table and the effective microphone coverage of your CP960 system expands to fill the entire table length. Each CPW90 captures voice audio from participants within its 3-metre pickup radius and transmits it wirelessly to the CP960’s unified audio processing engine — which combines input from all microphones into a single, balanced, HD-quality audio stream for remote participants. Every seat at the table receives equal microphone coverage — regardless of distance from the CP960 unit.

❓ “Will the wireless connection between the CPW90 and CP960 be stable enough for critical business calls?”

The CPW90 uses DECT wireless technology — a dedicated digital wireless standard specifically designed for voice communication applications, operating on its own 1.9GHz frequency band that is completely separate from Wi-Fi, Bluetooth, and all other wireless technologies used in the office environment. DECT’s dedicated frequency allocation means there is no competition for wireless spectrum with your network infrastructure — the CPW90 maintains a stable, latency-free connection to the CP960 with no dropouts, no interference, and no degradation from Wi-Fi congestion. For business-critical conference calls, DECT wireless reliability is the gold standard.

❓ “We have a very long boardroom table — can we use two CPW90 units simultaneously?”

Yes — and this is one of the CPW90’s most important deployment capabilities. Up to two CPW90 expansion microphones can be paired and operate simultaneously with a single CP960. For a long boardroom table, deploy one CPW90 at each end of the table, with the CP960 at the centre — creating a three-point microphone coverage system that provides consistent HD audio capture from every seat at the table, regardless of table length. The CP960’s audio processing engine manages input from all three microphone sources simultaneously, delivering a unified, balanced audio stream to remote conference participants.

❓ “Our meeting rooms have loud HVAC systems and projector fans — will the CPW90 pick up that noise?”

Yealink’s Noise Proof Technology is specifically engineered for exactly this scenario. The CPW90’s intelligent noise suppression algorithms continuously distinguish between human voice and environmental ambient noise sources — including HVAC systems, projector fans, air conditioning units, and other constant background noise sources. These sounds are actively suppressed from the audio signal in real time, ensuring that only voice audio is transmitted to remote conference participants. Meetings in rooms with challenging acoustic environments benefit most dramatically from Noise Proof Technology — because that is precisely the environment it was designed to address.

❓ “How does muting work when we have the CPW90 and CP960 both on the table?”

Mute control is fully synchronised across the entire CPW90/CP960 system. Pressing the mute button on the CP960’s touchscreen interface simultaneously mutes all connected CPW90 expansion microphones — and the red LED ring on each CPW90 illuminates to provide clear visual confirmation of the muted state to all table participants. Equally, pressing the dedicated mute button on any CPW90 unit mutes the entire system — including the CP960’s internal microphones. This bidirectional, synchronised mute control means that any participant at the table can manage the mute state from their nearest microphone unit, without needing to reach across the table to the CP960. The LED status confirmation ensures that mute state is always clear to every participant.

❓ “Will the CPW90 work with our existing conferencing software like Microsoft Teams or Zoom?”

The CPW90 functions as a microphone extension of the CP960 conference phone — so its compatibility with conferencing platforms is determined by the CP960’s platform support. The CP960 is compatible with Microsoft Teams (via Yealink Teams Edition firmware), Zoom, Cisco Webex, and standard SIP-based conferencing — and in each case, audio from the CPW90 expansion microphones is processed and presented to the platform exactly as if it originated from the CP960’s internal microphones. From the conferencing platform’s perspective, the audio is seamlessly unified — the CPW90’s wireless expansion is completely transparent to the software.

❓ “How long does the CPW90 battery last, and what happens if it runs out during a call?”

The CPW90’s 8-hour battery life is engineered to cover a full business day of conference activity on a single charge — accommodating even the most meeting-intensive schedules without mid-day recharging. The battery status LED and low battery alert provide advance warning before the battery is depleted, giving meeting organisers time to connect the USB charging cable before a critical session. In the event that a CPW90 does run low during a meeting, the charging cable can be connected during the session — the CPW90 continues operating normally while charging, with no interruption to its microphone function.
