Anker PowerConf S500 vs Yealink CP900 Comparison

Anker PowerConf S500

Four mics with a 5 m rated pickup and 32 kHz ultra-HD voice sampling put the S500 in a different class from Anker's own S3. Anker rates it for 12 people, or 20 when two units are linked. When I ran it myself in a ten-seat room, people at the far end stayed clear, which is the longest reach I'd expect from any puck here.

Yealink CP900

Six mics with a 2 m pickup cover a desk or a small room for up to six people. Conference mode runs from 115 Hz to 7 kHz, which is narrower than the Jabra Speak2 75's super-wideband. However, in my own run with a trio at a compact table, voices stayed clear across the table.

A 1.75-inch full-range driver pushes 10 W, with a range from 80 Hz to 20 kHz. That's more than three times the S3's output, and there's a music mode for playback between calls. At a moderate volume, it filled a medium room without the harsh edge small pucks get when pushed.

Yealink CP900

A 7 W peak, 3 W RMS speaker is loud for its size. USB music mode extends the range to 16 kHz, so playback sounds clearer than in conference mode. At a moderate volume, it filled a small room without distortion. That's more headroom than the Speak2 55, but less body than the Poly Sync 60's two drivers.

The S500 connects by USB-C, over Bluetooth 5.4, or through the included dongle. Pairing two units wirelessly extends coverage for larger rooms. That combination is rare at this price. Linking a second S500 took a moment with both units side by side. Once linked, place them at either end of the table rather than bunched in the middle.

Yealink CP900

The CP900 connects over USB and Bluetooth 4.2, with the optional BT50 dongle for a PC. It can handle three devices and even merge a USB call with a Bluetooth call, which few pucks can do. Merging a mobile call into a Teams call on the laptop took a moment with the on-device controls.

Anker PowerConf S500

Anker rates the 6,000 mAh battery at 13 hours of talk time and 16 hours of playback, with a slow 4-hour charge. That's fine for a meeting room where it lives near a socket, but less suited to a full day of travel. In my own back-to-back calls, I'd plan on a working day's runtime at room-filling volume before it needs the cable.

Yealink CP900

The 2,450 mAh battery is rated for 12 hours of talk time, with a 3-hour charge. That matches the Speak2 55 and covers a working day. Across a string of calls, I'd expect a long runtime before charging. For multi-day use, the Anker S3 at 24 hours or the Poly Sync 40 at 30 last much longer.

Anker PowerConf S500

Certification covers Zoom Rooms and Google Meet. That makes the S500 one of the few pucks you can drop into a Zoom Room or a Meet hardware space and expect the call controls to behave. Teams still works over USB audio, but without Teams-specific button features. If Teams is your standard, check our Microsoft Teams Rooms equipment guide before you buy.

Yealink CP900

The CP900 is certified for Microsoft Teams and has a dedicated Teams button. Mute and call controls stay in sync with the Teams desktop client. For a full Teams Room, our Teams Rooms equipment roundup covers larger options.
