Polycom VoxBox Review

The Polycom VoxBox is a device that has been designed specifically with conference calls in mind. And it really shows.

The voice quality is impeccable, it is easy to use, and it is as solid as a rock as well.

It does have some flaws, too though. But they pale in comparison with all the benefits it brings to the conference table.

The squared VoxBox is loaded with powerful features, while its surface is robust and water-resistant.

At a Glance

The VoxBox is Poly’s answer for the ultra-compact speakerphone category. It is perfect for individual use as well as for small conference meetings with between 4 and 8 people.

It is suitable for beginner users as it is extremely user-friendly. Teams are guaranteed to learn quickly how to work with the device.

It has the most basic buttons, and the plug-and-play connectivity makes it a breeze to connect with other devices. In addition, it has an LED indicator with changing colors for visual notifications.


The VoxBox is a very recognizable compact speakerphone. The reason for this is that it is one of the few products in its category to have a square form factor. In contrast, most other compact speakerphones are rounded.

Overall, the device’s built quality is substantial. It is light enough to be portable but heavy enough to feel reassuring.  

One of the more stand-out design features is the liquid-resistant and anti-dust surface. When it comes to premium tech pieces, this type of security is always nice to have.

For extra convenience, the VoxBox comes with a nice, padded neoprene case. This accessory comes in handy when the VoxBox needs to be taken places.

The VoxBox has buttons for the basic call operations. Answer/Reject, Mute/Unmute, Volume Adjustment buttons, all handily placed together at the corner of the device. 

Audio Performance

Polycom is not short on confidence by promising ‘legendary conference quality’ from the VoxBox. So, does the device live up to such a definition?

It absolutely does. By far, this is one of the best two-way audio performances by any compact speakerphone.

The VoxBox is packed with all the technology necessary for catering a life-like conversation in any small-to-medium conference room.

The Polycom HD voice system captures an expanded frequency range of the human voice. In terms of clarity, this creates the effect that the person on the other side of the line is in the same room.

Moreover, the speakerphone of the VoxBox can get quite loud. This way, it ensures that every participant in a small conference room will be able to hear the other party clearly. This tiny little box is absolutely packed with power.

The VoxBox performs just as flawlessly for outgoing speech transmission. The VoxBox’ microphones are optimized to recognize and amplify human speech.

This can be attributed to Poly’s patented NoiseBlock technology for eliminating background noises.

The VoxBox is a perfect fit for a table of similar dimensions.

The device is supplied with 4 directional microphones located at the edges of the speakerphone. With a pick-up range of 10 feet, the VoxBox is a perfect fit for a medium square or round table.

Overall, the microphones exhibit awesome quality and are very reliable. Together, they are able to catch voices coming from all directions. Even when speech is not directed at the microphones, they were able to pick it up.

Connectivity & Integration

The VoxBox connects to other devices via either USB or Bluetooth.  

With both USB and Bluetooth, all it takes is a simple plug-and-play procedure for connecting the VoxBox to other devices. No additional drivers need to be downloaded or installed.

However, downloading the free VoxBox Companion Application (available for free (polycom.com) might be a good idea. With this app, the speakerphone’s firmware is automatically updated and provides users with a bit more control over the VoxBox. 

The VoxBox comes with 2 USB cables with varying lengths. The first is 4 feet long, while the other extends up to 10 feet.

The longer one is intended for more complex conference room set-ups. It has loops to enable locking it to a conference table.

The Poly VoxBox is compatible with all recent versions of Windows (7, 8.1, 10) and Apple OS (Yosemite, El Capitan, Sierra).

The VoxBox speakerphone can pair with up to 10 devices and connect with up to two devices at once. However, the speakerphone can only transmit audio for one device at a time.

If the VoxBox remains in the conference room all the time, the limit of 10 paired devices quickly fills up. This would not have been a problem if the already paired devices could be removed from the pairing list.

It will not be very convenient for bigger organizations if only a selected few of 10 total devices can pair with the VoxBox.

A simple “clear pairings nightly” or “pairings are temporary and go away on disconnect” setting on the Companion application would fix this.

Another minor problem with the VoxBox is the inability to set a BLE name on the device. This can be a problem if there is more than one VoxBox device in the office, as users will not know which one they are connecting to.


The VoxBox runs on a rechargeable, built-in Lithium battery. The battery is charged from a PC via any of the USB cables.

Alternatively, the USB cables can also be plugged into a power supply adaptor. Keep in mind that such an adapter must be purchased additionally, as the VoxBox does not come with one by default.

Now, if the VoxBox has a major weakness that must be the battery endurance. The device can go up to 6 and a half hours without being charged. This is not bad, but most other similar gadgets last for at least 8 hours.

At the same time, it takes between 3 and 6 hours to fully charge. Three hours sounds good, but 6 is too much. For this reason, users are advised to charge the device via the power supply adaptor as it is the quicker option.


The VoxBox comes with Poly’s standard 1-year warranty.

Please take note that this applies to authorized resellers only.

Final Word

As a whole, the Polycom VoxBox is a superb conference device. It fulfills its intended function beautifully.

The mere fact that Poly’s promise for ‘legendary voice quality’ holds true should be sufficient for most users.

This, in combination with the tidy design and robust built, turn the VoxBox into a go-to business speakerphone.
