Poly Plantronics EncorePro EP545 Convertible USB Headset

Hand the same headset to five different agents and you'll get five different opinions about how it should sit — one wants the security of a full headband, another finds it too warm and prefers an ear hook, a third wants nothing touching the top of their head at all. The Poly EncorePro EP545 solves that by being all three: a convertible headset that switches between over-the-head, over-the-ear, and behind-the-neck without changing the hardware.

It's the convertible model in Poly's EncorePro 500 Digital series, sitting alongside the mono EncorePro EP515-M and stereo EncorePro EP525 I've written before — same digital audio calibration, same USB-A-and-USB-C-on-one-cable design, same remote firmware updates. It's mono, weighs between 22 and 32 grams depending on which wearing style you've built it into, and connects straight to a computer with no external amplifier required.

Does the EncorePro EP545 need an amplifier?

No — the Poly EncorePro EP545 plugs directly into a USB port and works immediately, with no amplifier or direct-connect cable to buy separately. That's a real distinction from its analog sibling, the EncorePro HW540, which is built on the same 3-in-1 wearing concept but requires a separately-purchased amplifier or bottom cord to connect to a phone. The EP545 skips that step entirely by being USB-native.

Three wearing styles, one headset

Every EncorePro EP545 ships ready for all three configurations — the choice happens on the user's desk, not at the time of ordering.

• Over-the-head. A full headband for the most secure, stable fit — the pick for agents who move around or want zero chance of the headset shifting.
• Over-the-ear. A bendable ear hook with no headband at all — for anyone who finds a full band warm or constraining over a long shift.
• Behind-the-neck. A low-profile band that sits below the headband line — popular with anyone who wears glasses or just prefers nothing crossing the top of their head.

Is the EncorePro EP545 certified for Microsoft Teams?

This version of the Poly EncorePro EP545 is UC-certified rather than formally Teams-certified — it works with Microsoft Teams and every other major UC platform, but without the dedicated Teams button. Poly also offers an EncorePro EP545-M variant that adds Teams certification and that button specifically, mirroring the same UC/Teams split as its EncorePro EP525 sibling.

Works with more than just Teams

The Poly EncorePro EP545 is UC-certified across the platforms a real contact center actually runs, not just the big-name video call apps.

• Five9
• AWS
• Unify

Built to survive the twist

The noise-canceling boom on the EncorePro EP545 rotates 290 degrees — noticeably more than the 180-degree rotation common on most USB headsets — which matters specifically because this headset changes physical configuration between its three wearing styles. A boom that only rotates halfway around can't reposition cleanly for both an over-the-head and a behind-the-neck fit; this one can.

The cable runs 85.8 inches (218 cm) end to end, long enough to reach a laptop from across a standard desk without stretching, and the composite build keeps the whole thing light regardless of which of the three configurations it's built into. SoundGuard-class acoustic hearing protection guards against sudden loud spikes over a shift, and the same dynamic audio adjustment and remote firmware updates that run on the rest of the EncorePro 500 Digital series apply here too.

One button for calls, another for hold

Inline controls handle answer/end, mute, and volume, and the EncorePro EP545 adds a dedicated hold button plus a single combined button for putting both audio and video on hold at once — useful on the video calls where a normal headset only ever thought about the audio side.

The Poly EncorePro EP545 is the headset for a team that won't agree on how to wear one — three configurations built into a single part number, no amplifier to source separately, and a boom that actually rotates far enough to make all three styles work properly. Order it once, and let each person on the floor set it up their own way, backed by HeadsetPlus's lifetime support.
