Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What customers like about Poly Sync 20

  • Excellent call clarity with an effective three-microphone array
  • Great background noise cancellation and echo reduction
  • Highly portable, lightweight design with included carrying case and lanyard
  • Impressive battery life (up to 20 hours) and doubles as a phone power bank
  • Seamless integration and certification with Microsoft Teams and Zoom
  • IP64 dust and water resistance makes it durable for outdoor use
  • Convenient touch-sensitive controls and customizable programmable button
  • Clear full-duplex audio allows for natural simultaneous conversations

What customers don't like about Poly Sync 20

  • Audio quality drops significantly to standard telephone quality during active voice calls
  • Subpar bass performance and audio distortion at high volumes when playing music
  • The attached USB cable is stiff and difficult to wrap or stow away neatly
  • Requires sacrificing a USB port for the dongle instead of offering direct PC-to-Bluetooth pairing
  • Poly Lens companion software can be buggy and lacks advanced customisation options
  • Volume controls can occasionally jitter and sync poorly with Windows OS taskbar controls
  • Actual battery life falls short of the advertised 20 hours during heavy call or charging usage

Verdict

The Poly Sync 20 is a portable personal smart speakerphone measuring 34 x 95 x 182 mm and weighing 360g, designed primarily for hybrid work environments. Key specifications include a steerable three-microphone array with a 2-meter (7 ft) pickup range and full-duplex audio with echo and noise reduction, alongside a 40mm speaker driver boasting a frequency response of 80 Hz to 20 kHz supported by dual passive radiators. Main pros include an IP64 dust and water resistance rating, a built-in 3,200 mAh battery that offers up to 20 hours of talk time and doubles as a smartphone power bank via its integrated USB-A charging port, and versatile connectivity via Bluetooth 5.1 or a hardwired USB cable. However, minor cons include a permanently attached USB cable that can be rigid and difficult to manage within its base slot, a lengthy 4-hour recharge time, and occasional software mute synchronization issues when connecting directly via native laptop Bluetooth instead of an official adapter.
