HP Blackwire 3310 Mono Headset

The HP Blackwire 3310 is a mono on-ear headset designed for professionals who spend long hours on calls. It connects via USB-C or a 3.5 mm jack for broad device compatibility. The lightweight build and adjustable fit support all-day comfort in office or mobile environments.

Dual connectivity with 32 Ohm drivers

The 32 Ohm drivers deliver a frequency response of 20 Hz to 20 kHz for clear voice reproduction. USB-C provides digital audio and inline controls while the 3.5 mm connection works with analog ports. The 7.10 ft cable gives ample reach at a desk without excess slack.

Monaural design with noise-cancelling microphone

The single-ear cup leaves one ear open to surroundings, which suits users who must stay aware of colleagues or announcements. An omni-directional boom microphone with noise cancellation reduces background sound for clearer transmission. This headset is not suited for stereo media playback or immersive audio applications.

Questions about this item

Will the 3.5 mm jack on the Blackwire 3310 work with my older laptop that only has a headphone socket?

Yes — the headset includes a 3.5 mm mini-phone connector so you can plug it directly into any legacy audio port.

How can I confirm the 32 Ohm drivers are delivering the full 20 Hz to 20 kHz range after I plug it in?

Play a broadband test tone or music you know well; clear low notes and crisp highs mean the drivers are performing across the specified range.

Does the box contain both the USB-C and 3.5 mm cables, or must I buy one separately?

The headset has a single 7.10 ft cable with both USB-C and 3.5 mm plugs built in, so no extra cable is needed.
