Poly C3210 Mono USB-A Corded Headset

Keep one ear available for colleagues and surrounding activity while handling calls through a PC or USB-A-equipped workspace. The Poly Blackwire C3210 uses a monaural, supra-aural wearing style: one padded earpiece provides call audio without fully isolating the wearer. Its over-the-head headband supports a stable fit for contact-center desks, office users, assisted-listening environments and shared communications stations. A boom microphone positions voice pickup close to the speaker, while noise-cancelling microphone technology helps reduce surrounding noise during conversations. Wired USB Type-A connectivity supplies the host connection for compatible computers and communication applications without Bluetooth pairing or battery charging. Audio coverage from 20 Hz to 20 kHz supports spoken calls as well as training, multimedia and general PC audio. Part number 209744-104 is the black USB-A configuration in the Blackwire 3200 Series. This C3210 configuration uses a single earpiece rather than a two-ear stereo arrangement, making it appropriate where users need to remain aware of nearby conversations, alerts or visitors. The corded construction also gives assigned desks and shared workstations a direct, repeatable connection method. Select it when the required endpoint is a mono over-the-head headset with a USB Type-A host interface and a noise-cancelling boom microphone.
