USB 360° Speakerphone for Conferencing

The Black SP300U is a USB speakerphone designed for PC and Mac conferencing. It combines a speaker and omnidirectional microphone in one unit for hands-free calls. The device connects via USB and works with major platforms such as Zoom, Microsoft Teams and Skype. It is suited for individuals or small groups who need clear audio without a headset.

Upgrade from Built-in Laptop Audio

This unit replaces the internal microphone and speakers on a laptop or desktop for calls involving up to four people. The jump is worth it when built-in audio sounds muffled or picks up keyboard noise during meetings. The 360-degree microphone captures voices from around the table up to about three metres away. A 3.5 mm earphone port is included for private listening when required.

Sustained Call Clarity and Playback

Echo cancellation and noise reduction maintain consistent voice quality throughout long conferences. The speaker delivers HD Voice bandwidth for natural conversation tone during extended sessions. It can also serve as a compact playback speaker for music between calls when set as the default audio device. Plug-and-play operation requires no driver installation or external power.

Questions about this item

How much desk space does the 14.33in wide by 9.06in deep speakerphone need?

The unit measures 14.33 inches wide, 12.83 inches high and 9.06 inches deep, so allow at least that footprint on a flat surface.

What is the correct way to select this speakerphone in Zoom or Microsoft Teams?

Open the meeting settings, choose SP300U as both the microphone and speaker, then verify the input level moves when you speak.

Does the 3.5mm earphone port need cleaning or replacement over time?

The 3.5mm jack is a passive port; keep it free of dust and debris, but no scheduled maintenance or replacement is required.
