Poly S55255089
A wired 131g on-ear design with 32mm drivers and a noise-canceling boom mic uses SoundGuard DIGITAL to cap sudden volume spikes at 118 dBA for hearing safety. Plug-and-play USB-C with an included USB-A adapter and one-touch call controls simplify PC/Mac operation, while Dynamic EQ tunes voice for wideband telephony. It suits desk-bound professionals logging full days on conference calls who prioritize clear vocal capture and ear protection over mobility.
