Purpose-built speakerphone for remote workers

The Anker PowerConf S330 USB Speakerphone A3308 is designed for home-office professionals who need clear two-way audio during video calls. Its 4-microphone array captures voices within 3m and smart voice enhancement suppresses background noise. Plug-and-play USB-C connectivity with an included USB-A adapter works instantly with leading conference platforms. The compact 4.72 x 4.72 x 1.36 inch form factor fits any desk.

Wired USB limits wireless convenience

A wired USB-C link provides the most stable speakerphone experience but tethers the unit to the host computer. The supplied USB-C to USB-A adapter ensures compatibility with older ports yet adds no wireless freedom. Full-duplex audio and auto echo-cancellation rely on the USB connection and AnkerWork software on PC or Mac. Users who must move around the room during calls will find the cable restrictive.

360-degree pickup radius decides fit

Four high-sensitivity microphones deliver 360° voice coverage up to 3m, making the S330 suitable for solo users or small huddle groups. A 1.75" driver with dual passive bass radiators adds depth to speech and music playback. Buyers needing coverage beyond 3m or wireless Bluetooth pairing should consider other solutions.

Questions about this item

Should I pick the PowerConf S330 or another model number for a small meeting room?

The S330 is a single USB speakerphone with four microphones covering voices up to 3 metres, so one unit suits a small room; add a second only if the space exceeds that range.

What does the 360° voice coverage figure mean once the speakerphone is on a desk?

Four high-sensitivity microphones pick up every speaker within a 3 metre radius, so participants can sit anywhere around the table without leaning toward the device.

Does the USB-C connection with the included adapter limit audio quality or features?

The wired USB-C link — with a USB-A adapter supplied — provides a stable, driver-free connection that supports full-duplex audio, echo cancellation and the AnkerWork software suite.
