Frequently asked questions about this product
Is this Blackwire 3325 the Microsoft Teams certified version?
Yes, reference 8X222AA is the Microsoft Teams certified variant of the Blackwire 3325: it is tested and optimised for video conferencing, with no manual setup required.
Does the headset connect to a phone or a tablet?
Yes, through the 3.5 mm jack that accompanies the USB-C connection: the same headset goes from the computer to the mobile with no dongle or pairing.
Does it work on a computer without a USB-C port?
Yes, a USB-A adapter is supplied: the headset connects to any workstation, on Windows or macOS, with no prior installation.
Can you answer calls and mute the microphone from the cord?
Yes, the call, volume and microphone mute controls are close at hand on the cord: you manage the call without taking your eyes off the meeting window.
Can the mic boom be positioned close to the mouth?
Yes, it is adjustable: you position it as close as possible so that your voice is picked up at short range, which clearly improves intelligibility compared with a laptop's built-in microphone.
131 g: is it comfortable for a full day of meetings?
It is an on-ear headset: the cushions rest on the ear rather than around it, on a headband described as sturdy. The headset is rated at 131 g, at the lower end of the average for wired stereo models.
Do you need to install software to use this headset?
No, it is plug-and-play: recognised as soon as it is plugged in, on Windows and macOS alike. Nothing to pair, nothing to charge.
Is this POLY Blackwire 3325 Teams new and under warranty?
Yes, new in its original Poly packaging, USB-C/A adapter included. Your invoice serves as the warranty document and covers 1 year on this reference, the 8X222AA.
