Poly BackBeat 500 Wireless Headphones, Bluetooth, 18 Hours | AV Audio

Stay productive and comfortable through long listening sessions with the Poly BackBeat 500 Series wireless headphones. Designed for everyday mobility, they combine Bluetooth connectivity with a wired 3.5 mm backup jack so audio keeps flowing when battery power runs low. Up to 18 hours of listening and talk time supports full-day use across meetings, travel, and downtime. The over-the-head, binaural design uses circumaural earcups and memory foam cushioning to help reduce fatigue during extended wear. 40 mm drivers deliver the signature Poly sound profile, while the wideband-enabled microphone supports clearer voice pickup for calls and conferencing. On-ear controls make it easy to manage playback and calls without reaching for your device. DeepSleep mode helps preserve charge when the headphones are idle, and support for connecting multiple devices adds flexibility in mixed-device environments. For teams and individuals who want dependable wireless audio without paying for features they will never use, this model offers a practical balance of comfort, battery life, and everyday performance.
