Mono USB-A Headset for Calls

The HP Poly Blackwire 3310 is a mono on-ear headset built for voice communication. It connects through a USB-A plug and includes a 3.5 mm mini-phone jack for additional device compatibility. The single-ear design keeps the other ear open to the surrounding environment.

Wired On-Ear Fit for Desk Setups

A 7.15 ft cable provides reach across a typical desk without adding wireless pairing steps. The 32 Ohm impedance and 20 Hz to 20 kHz frequency response are tuned for speech clarity rather than music playback. An omnidirectional boom microphone captures the user’s voice while the open on-ear cup reduces heat buildup during long sessions.

Upgrade from Basic Earbuds or Built-In Mic

This headset replaces earbuds or laptop microphones when consistent call quality and all-day comfort are required. The mono form factor is not suited for stereo media consumption or immersive gaming. Buyers who need two-ear coverage or wireless freedom should consider a different model.
