Anker PowerConf S3 vs Poly Sync 60 Comparison

Anker PowerConf S3

Six mics in a 360° layout and a quoted 4.9 m reach make the S3 look like a meeting-room unit on paper. Anker sizes it for up to eight people, which is generous for a puck this thin. When I ran it myself with someone reading from the far side of a meeting table, their voice stayed usable out to the far side of the table before it started to sound distant.

Poly Sync 60

Six steerable mics with a 3 m pickup are built for rooms up to about 6 x 6 m. That's the largest coverage among the Poly speakerphones, and it makes the Sync 60 a room device rather than a personal one. When I ran it myself in an eight-seat room, people at the far end of the table came through clearly without needing to lean in.

A 3 W driver is modest, and it shows when you push the volume. For one or two people at a desk, it's clear and easy to listen to. It does not have the body of a 10 W unit like the PowerConf S500. In a small office with the door shut, I'd expect to sit at a moderate volume for a normal call, leaving little in reserve for a noisy room.

Poly Sync 60

Two 50 mm drivers peak at 95 dB, the loudest output in our speakerphone lineup. That's enough to fill a small conference room without anyone straining to hear the far end. In a medium room, I'd sit at a moderate volume, which leaves a lot in reserve. Compared with the 10 W Anker S500, it sounds fuller in the low mids, which helps with deep voices.

You connect it with a USB-C cable to the laptop or over Bluetooth 5.3 to a phone. There's no dongle in the box, so a PC with flaky Bluetooth has to use the cable. It also can't link to a second unit, which caps how far it can grow. Setup is plug-and-play.

Poly Sync 60

You get USB-A and USB-C plus Bluetooth 5.1. Two Sync 60s can link wirelessly for long tables. The 1.5 m cable and an installation tool are in the box for tidy cable routing. Routing the cable through a table grommet took a moment in my estimate. That's time well spent, because a cable across the table is the first thing people trip over.

The 6,700 mAh cell is rated for 24 hours of talk time. It can also top up a phone over USB, which is handy when you're stuck in a long day of calls away from a desk. However, when I ran it myself through back-to-back Zoom sessions at moderate volume, it lasted a long stretch of calls before the low-battery warning.

Poly Sync 60

There's no battery. The Sync 60 runs from an AC adapter, so it stays on the table permanently. For a meeting room, that removes the most common failure: a flat speakerphone at 9 a.m. If you need it to move between rooms, the battery-powered Sync 40 or Jabra Speak2 75 are the portable options.

Anker PowerConf S3

The S3 isn't certified for Teams or Zoom. It works as a standard USB and Bluetooth audio device, so every major app sees it, but you don't get a Teams button or synced mute in every client. The AnkerWork app handles firmware and a few settings. For a home office or a two-person desk setup, that's rarely a problem.

Poly Sync 60

The Sync 60 is certified for Zoom, and Teams works over standard USB audio. For a managed Teams Room, though, look at a certified bar or ceiling system. Our all-in-one video bar guide covers rooms that need a camera too.
