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.
