The Poly Blackwire 3325 is built for exactly that split. It's the stereo headset in Poly's 3300 series with a 3.5mm connector added, so the same headset that blocks out the open office on a Teams call also plugs into a phone on the move.\u003c\/p\u003e\n\n\u003cp\u003eIt's the last piece of the 3300 lineup — the mono desk model is the Blackwire 3310, the mono hybrid is the 3315, the stereo desk model is the 3320, and the Blackwire 3325 is the stereo hybrid: both ears, both devices. It comes in USB-A and USB-C, each available as a standard UC model or Microsoft Teams certified.\u003c\/p\u003e\n\n\u003ch2\u003eBuild the exact Blackwire 3325 you need\u003c\/h2\u003e\n\n\u003cp\u003eFour versions, split by two choices: which USB port matches your computer, and whether you want the dedicated Microsoft Teams button.

That's not active noise cancellation; there's no electronics erasing the office, just both ears covered by soft leatherette cushions built for a full day of wear. And because it carries a 3.5mm connector alongside the USB connection, the same Blackwire 3325 that ran your desk call over Teams plugs into a phone the moment you're out the door.\u003c\/p\u003e\n\n[compare]\n\u003cdiv\u003e\n\u003cstrong\u003eBlackwire 3325 — stereo, with 3.5mm\u003c\/strong\u003e\u003cbr\u003eBoth ears blocked, true stereo for media, plus mobile connectivity.

It won't work directly with a phone that's dropped the jack in favor of USB-C or Lightning only — and that's most current iPhones and a growing share of newer Androids.\u003c\/p\u003e\n\n[callout type=\"honest\"]Check your phone before you count on the mobile side of the Blackwire 3325. Plenty of business phones, tablets, and older handsets still carry a 3.5mm jack, and the connector plugs straight in. But if your phone routes everything through USB-C with no separate headphone port, you'll need an adapter — the 3325's 3.5mm plug won't seat in it directly. Worth five minutes to confirm before buying for the phone side.[\/callout]\n\n\u003ch3\u003eMicrosoft Teams certified, or not — what actually changes\u003c\/h3\u003e\n\n\u003cp\u003eEvery Blackwire 3325 works with Microsoft Teams. What Teams certification adds is a dedicated button on the inline controls — one press brings Teams to the front, joins or answers a meeting, checks notifications — plus Poly's tested Teams audio profile. The standard UC version runs Teams fine without it, and works with Zoom, Webex, Avaya, and Cisco just the same.\u003c\/p\u003e\n\n[stat]~96g headset, ~130g with inline control[\/stat]\n\n\u003cp\u003eThe Blackwire 3325 is the headset for a workday that doesn't stay at one desk — both ears covered for focus on the computer, a real stereo mix for the music that gets you through the gaps, and a 3.5mm jack ready the second you switch to the phone. Pick your USB port and your certification, and it's plug-and-play on both sides, backed by HeadsetPlus's lifetime support.\u003c\/p\u003e\n\n\u003cdiv data-tab=\"whats-in-the-box\"\u003e\n\u003cul\u003e\n  \u003cli\u003ePoly Blackwire 3325 stereo headset with inline control module\u003c\/li\u003e\n  \u003cli\u003eUSB connection to your computer (USB-A or USB-C, depending on version)\u003c\/li\u003e\n  \u003cli\u003e3.5mm connector for mobile phones and tablets\u003c\/li\u003e\n  \u003cli\u003eLeatherette ear cushions (fitted, both ears) and quick start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe inline module handles answer\/end, volume, and mute on every version.
