Mono on-ear headset for calls

The HP Poly Blackwire 3310 is a monaural on-ear headset designed for voice calls and online meetings. It connects through USB-C and includes a USB-C to USB-A adapter plus a 3.5 mm mini-phone plug for broad device compatibility. The 7 ft cable gives freedom of movement at a desk or in a home office. Impedance is 32 Ohm for clear speech reproduction.

Check ports and wearing preference

Verify that your computer or phone offers a USB-C, USB-A or 3.5 mm audio jack before ordering. The headset is mono, so only one ear is covered; users who need stereo audio or dual-ear noise isolation should choose a different model. No battery is embedded, so power always comes from the host device.

Replaces older mono USB headsets

This model upgrades from earlier mono headsets that lack a 3.5 mm fallback or a USB-A adapter. The jump is worth it when you switch between USB-C laptops, USB-A desktops and mobile devices with a headphone jack. It does not suit buyers who want stereo playback, wireless freedom or active noise cancellation.

Questions about this item

Does the 8X215AA include both the USB-C and 3.5 mm connections or must I buy an adapter separately?

The headset ships with a USB-C plug and a USB-C-to-USB-A adapter in the box, so both USB-C and USB-A ports are covered; the 3.5 mm jack is built into the headset cable and requires no extra adapter.

Should I choose the mono 3310 or a stereo version for single-ear use?

The 3310 is monaural by design, giving you one ear cup for calls while leaving the other ear open; if you need stereo sound for music or dual-ear coverage, select a stereo model instead.

What does the 32 ohm rating mean when I plug the headset into my laptop?

At 32 ohms the headset draws modest power, so any standard laptop USB-C or 3.5 mm port will drive it to clear call volume without an external amplifier.
