Poly Sync 60chat_bubble_outlineFrom real comments

Multi-unit pairing is the Sync 60's headline feature. Many commenters asked about linking a Sync 60 with other Sync 40 or Sync 60 units, and one reviewer called the daisy-chaining setup 'a great idea, very convenient,' especially useful when larger C60 systems weren't available. Another user described successfully pairing new Poly devices during a live emergency when their main video conferencing system failed, calling it a technology lifesaver. However, some report that pairings reset if a unit loses power, meaning devices must be re-paired, and one commenter specifically asked about wireless pairing stability before committing to a multi-unit purchase for their office.

Audio quality draws mixed but mostly positive comments on noise filtering. One reviewer highlighted the Sync 60's 'great sound filter' compared to Jabra, emphasizing that echo and background-noise cancellation performed well during calls, which matters for busy office environments. Despite this praise, mic quality opinions diverge: another commenter, testing at fifteen feet, felt the smaller Sync 20's microphone held up reasonably well against the Sync 60. A separate, more critical comment bluntly stated the microphone was poor, claiming an iPhone's built-in speakerphone sounded clearer, suggesting the Sync 60's mic performance may vary by distance or use case.

Speaker volume and power design frustrate some buyers. Multiple users flagged the built-in speaker as underwhelming, with one saying it sounded too quiet across an iPhone, Mac, and Windows setup, even quieter than an Apple HomePod Mini at maximum volume. Separately, buyers were surprised the Sync 60 lacks an internal battery unlike the Sync 20 and Sync 40, meaning it must stay tethered to AC power at all times. One commenter called it 'brilliant' but was 'so sad' that AC dependence limited its flexibility for mobile or temporary meeting setups.
