Wired USB-A headset with Microsoft Teams button

The Plantronics Blackwire 3320 connects through a USB Type A port and integrates a Microsoft Teams button for quick meeting access. Dynamic EQ and SoundGuard technology manage voice clarity and acoustic protection. An adjustable headband and 1.26 inch drivers aim for comfort during extended sessions. In-line controls handle volume, mute and call functions without software.

Suited for office workers who want plug-and-play

Designed for Windows and Mac OS environments where a wired USB-A link is preferred. The fixed boom microphone and over-the-head binaural design support daily calls. Not suited for buyers who need wireless freedom, a detachable boom arm, analogue connectivity or a lighter frame for all-day mobile use.

32 Ohm impedance and 20 Hz to 20 kHz response

Impedance of 32 Ohm and a frequency range of 20 Hz to 20 kHz define the electrical load and tonal breadth. These figures determine whether the headset matches the output stage of the host device and the audio fidelity required for voice and multimedia.

Questions about this item

What comes in the box with the Blackwire 3320 and do I need to buy anything else to use it?

The headset connects via its built-in USB-A cable, so no separate adapter or cable is required for a computer with a USB-A port.

The specs list model numbers 3320 and 213928-101 — which one should I order?

Both refer to the same headset; 3320 is the series name and 213928-101 is the manufacturer part number, so ordering either identifier will give you the identical product.

What does the 94 dB sound pressure level mean when I am on a call?

It indicates the maximum volume the drivers can produce, so speech will be clear and loud enough for typical office or home environments without distortion.
