Poly Blackwire 3210
A noise-canceling microphone with Dynamic EQ optimizes voice clarity on calls, while the 32-ohm driver and USB-C connectivity ensure consistent PC wideband audio. The 56-gram lightweight metal headband and fold-flat leatherette cushions provide all-day durability and portability for a monaural design that keeps one ear open. This headset is best for call center agents or office workers who need reliable, wired communication and prefer environmental awareness over stereo music playback.
