The Poly EncorePro 520 is a wired binaural headset designed for professional communication in call centers and virtual meetings. This two-ear model features a lightweight, padded adjustable headband and soft foam ear cushions, keeping the total weight at just 74 g for comfort during long shifts. Its design includes a flexible, adjustable noise-canceling microphone with positioning guides to ensure clear voice capture regardless of how you move. Technical performance is supported by an impedance of 32 Ohm and a frequency response ranging from 20 Hz to 16 kHz. To protect your hearing, the headset incorporates SoundGuard technology, which limits sudden loud sounds to below 118dBA. The unit connects via a Quick Disconnect (QD) system with a 0.78 m cable, allowing you to step away from your workstation without removing the headset. Measuring 11.1 x 14.9 x 6.7 cm, it provides a secure over-ear fit that helps block out office distractions.
