The Yealink CP700 speakerphone is the perfect personal assistant. There are two main reasons for that: It is extremely portable and the audio quality in both directions is brilliant. But what about any underlying weaknesses?

Like many other recent Yealink products, the CP700 is optimized for Microsoft Teams. And yet, there are moments in which the CP700 fails to synchronize with the MS Teams client. This is a look neither Yealink nor Microsoft has aimed for.

At a Glance

The CP700 is the smaller version of the Yealink CP900 speakerphone. The CP900 is specifically intended for huddle rooms and small board rooms. It even features the main two-way source of audio in Yealink’s small room system – the MVC300 II Teams

The CP700, on the other hand, is meant mostly for personal use. In terms of space, it is intended for a smaller and more private environment.

Whereas the CP900 is recommended for work with up to 5 people, the CP700 works best with up to 3 people. This is also reflected in the maximum output power of each. For the CP900, this is 7W. And for the CP700 – only 5W.

Protective Accessories

Upon receiving the CP700 package, the very first impression actually comes from the CP700’s protective zipper case. The case feels reassuringly tough. Users need not worry about any potential harm coming to the speakerphone while on the go.

The zipper case also accommodates the BT50 dongle inside a small elastic pocket.

The CP700 is so small that it almost fits in the pocket. Also, it is an extremely light piece of audio equipment.

Just like its bigger brother, the CP700 displays an elegant business look. This speakerphone has two main parts – upper and lower.

At the upper part is where the speaker and all the buttons are. The buttons are quite sensitive and they almost feel like a touchscreen. There are buttons for the main call-handling options, the volume adjustment ones, and of course – a dedicated Teams button.

The way this ‘Teams’ button works? When pressed, it evokes the Teams client on a desktop. And when pressed continuously, it activates the Cortana virtual assistant.

Right between the speaker and the buttons is the LED indicator. This indicator lights green during a call and turns red when the call is on hold or the mic is muted. Also, it displays the volume level whenever volume adjustments are being made.

The lower part of the CP700 functions as a cable management system. When not in use, users wrap the built-in USB cable around the lower part. When it comes to reducing the cable clutter, this cable management system is extremely helpful.

Is there a physical feature that the CP900 doesn’t have, but the CP700 does? Yes, there is – a kickstand. And this is important.  Because of the kickstand, the CP700 can be positioned with the speaker actually ‘facing’ the person. In turn, this can contribute to a more clear exchange. 

The kickstand allows for extra positioning flexibility and better speech input.


The CP700 performed solidly in every sound-related testing it underwent.

The audio delivered by the speakerphone is crisp and clear. In fact, the CP700 works perfectly well for streaming music. Its maximum output power is 5W, which is more than enough for small spaces.

As it turned out, CP700’s microphone system might actually be slightly better than the CP900’s. This is all a bit perplexing, given that the CP900 clearly has a more sophisticated arrangement at play. At least on paper. 

The CP900 has a 6-microphone beamforming array. Such an arrangement enables the CP900 to perform 360-degrees voice pick-up. In practice, the speakerphone is supposed to detect where the speech is coming from and amplify the signal.

On the other hand, the CP700 has only two omnidirectional microphones. Such a system works by picking up sounds from all directions, without necessarily prioritizing one source over another. But regardless, the CP700 delivered a slightly cleaner speech.

Nevertheless, one quality both systems share is the noise-cancellation system. Even though they slightly differ in clarity, both the CP900 and the CP700  prevented any significant amounts of background noise from entering the speaker. 

The CP700′ has a voice pick-up range of approximately 6 feet. This makes it ideal for an average round table.

The CP700 would be literally the perfect fit for small to average round tables.

Connectivity & Integration

The CP700 can be paired with up to 3 devices at once. It can link to a single device via its USB, to a second via its built-in Bluetooth 4.2, and to a third one via the BT50 dongle.

However, the CP700’s built-in Bluetooth is not exactly reliable for audio. The connection hardly remains stable, as this can quickly cause frustration.

Connect up to 3 devices at once. However, keep in mind that the built-in Bluetooth is not good for audio.

For good wireless audio connectivity, users are encouraged to use the BT50 dongle instead. Unlike the CP700’s built-in Bluetooth, the BT50 maintains a stable and consistent connection.  

*The BT50 is an optional accessory that must be purchased additionally.

Connecting the CP700 to other devices is straightforward. All it takes is a simple plug-and-play procedure. No additional configuration work has to be done.  

Microsoft Teams Integration

It was slightly disappointing seeing a ‘Teams-ready’ device failing to properly interact with the Teams client.

The first issue came when trying to use the CP700 with a desktop Microsoft Teams client in Island Mode. 

When in Island Mode, MSTeams is used alongside Skype-for-Business (This is something of a transitional period before users switch entirely to Teams).

With Team clients in this mode, the CP700’s Answer/Hold buttons did not work. Only the volume adjustment ones did. This means that users have to handle their calls from the Teams app. This, of course, is contraindicated when it comes to Teams-optimized hardware.

The other issue was experienced solely with Teams Only clients (Teams Only refers to when users have completed the transition from Skype-for-Business and currently rely on…Teams Only).

The dedicated ‘Teams’ button refused to switch over to the Teams desktop app. Instead, this had to be done manually. 

Such bugs are not uncommon. However, Yealink is a trusted manufacturer that will likely make amends where necessary.

Actually, most of the time the Teams integration worked well. It simply has to work well all the time to really earn the customers’ trust.

Charging & Durability

The CP700 runs on a rechargeable Lithium Polymer battery. The speakerphone is powered by inserting its USB 2.0 cable into a switching power adaptor. The USB cable has a length of 2.5 feet, which is a good length to have.

According to Yealink, the CP700 endures up to 9 hours of talk time. Just to put this in perspective, the CP900 endures up to 11.

The CP700 needs 3 hours to charge fully. One great thing about the CP700 is that it can be used while charging.

Unsurprisingly, the speakerphone has a power-saving mode. It activates after 30 minutes of user inactivity.


As with most Yealink products, the CP700 comes with a 1-year warranty (only when bought brand new, and from a certified reseller).

Final Words

Despite its flaws, the CP700 remains a rock-solid speakerphone. Especially, when these flaws are guaranteed to only be temporary. 

But other than that, the CP700 maintains the behavior of a reliable compact assistant. In the wake of the new normals and the flourishing of the home office, products like the CP700 are more relevant than ever.
