PowerConf S330 USB Speakerphone

The AnkerWork PowerConf S330 is a wired USB speakerphone built for home-office professionals who need clear conference audio without driver installation. It connects through USB-C and includes a USB-C to USB-A adapter for broad system compatibility. Four high-sensitivity microphones capture voices within a three-metre radius in 360-degree coverage. A 1.75-inch driver and two passive bass radiators deliver full-range sound for calls and music playback.

Suits solo and small-group meetings

This unit serves individuals and compact teams who want instant plug-and-play operation on Windows or macOS. It works with major conferencing platforms such as Zoom, Skype, Google Hangout, FaceTime and WebEx. Buyers who need wireless mobility, Bluetooth pairing or battery-powered portability should look at other devices. The fixed USB cable also limits placement flexibility compared with wireless alternatives.

Wired USB audio accessory

The speakerphone draws power and audio directly from a host USB port, so no external power supply is required. Its compact desktop footprint leaves room for a keyboard, monitor or laptop on the same surface. Smart Voice Enhancement suppresses background noise while boosting voices, and full-duplex communication lets both sides speak simultaneously. The included USB-C to USB-A adapter ensures connectivity with legacy and modern ports alike.

Questions about this item

Does this speakerphone need an external power supply or does it draw power from the USB port?

The PowerConf S330 is bus-powered over USB so it requires no separate power adapter; just connect it to a USB-C or USB-A port on your computer.

Will the four microphones still pick up my voice clearly if I keep using my older laptop with only USB-A ports?

Yes, the box includes a USB-C to USB-A adapter, so the 360° four-microphone array works with legacy USB-A ports exactly as it does with USB-C.

How can I confirm the speakerphone is active and capturing audio during a call?

When the S330 is connected and selected as the audio device, its built-in LED ring lights up and the 1.75-inch driver with dual passive radiators produces audible output, confirming it is working.
