Plantronics PW720 Polaris Premium Binaural Noise-Canceling Headset (HW720 + A10)
The PW720 covers both ears, no amplifier
The most comfortable way to cover both ears all day, and no powered box at the desk to do it — that's the narrow thing the Plantronics PW720 Polaris headset is. It pairs the premium 700-series binaural EncorePro with a cable that plugs straight into a headset-ready phone, so a noisy floor gets both-ears focus and premium leatherette comfort without an amplifier at every seat.
The PW720 is the EncorePro HW720 premium binaural noise-canceling headset bundled with the Plantronics A10 direct-connect cable — the premium, both-ears member of the Polaris family.
Premium binaural, because comfort decides it
Covering both ears is the right call on a noisy floor — it blocks the room and sharpens focus. But a both-ears headset asks more of the wearer than a mono one, and a heavy or hot binaural gets pushed off one ear by mid-afternoon, which throws away the whole benefit. The PW720 is built to keep both ears covered through the shift: plush leatherette pads on both ears, an ultra-light nylon-composite frame at 78 grams, and a reinforced headband.
Premium comfort is what makes a binaural work all day
A both-ears headset only delivers focus if it stays on both ears. That's why the premium build matters most on a binaural — and why the PW720 is the one to reach for when a floor has committed to both-ear headsets. The leatherette pads and light frame are tuned for eight hours of both-ear wear, and because it's a Polaris solution, all of that comfort plugs straight into a headset-ready phone with no amplifier to power or place. Premium where the wearer feels it, simple where IT deploys it.Direct-connect: no amplifier per seat
The PW720 includes the A10 direct-connect cable, which plugs the headset straight into a headset-ready phone's built-in amplifier — so there's no separate M22 amplifier to buy. "Polaris" is the legacy name for this direct-connect approach; the old P-series Polaris headsets were retired in 2008, and the HW720-plus-A10 combination is the modern equivalent.
The HW720 inside
The headset itself is the EncorePro HW720 — formerly the HW301N — the premium 700-series binaural headset: soft leatherette ear pads over both ears, a satin-finish nylon-composite body, a reinforced headband, and a telescoping noise-canceling boom that sits low and clear of your peripheral vision. It runs wideband audio, weighs about 78 grams, and is the both-ears, comfort-first step up from the mono PW710. Foam cushions are available if you prefer them, and both are replaceable.
The PW720 is the premium, both-ears, no-amplifier answer for a noisy floor on headset-ready phones — the leatherette HW720 and the A10 cable, matched and ready, blocking the room and skipping the amp at every seat. Confirm your phones take a direct-connect cable, and it's the most comfortable way to keep a floor locked onto both ears all day, backed by HeadsetPlus's lifetime support.

Phones. The PW720 connects to headset-ready phones that have a built-in amplifier — business systems from Nortel, NEC, Toshiba, Mitel, Aastra, 3COM, Comdial, ESI, and SciTec, among others. It is not for Cisco phones or for systems that require a specific HIS, HIC, or U10 cable. Confirm your exact model before ordering.
Connection. The included A10 direct-connect cable plugs the HW720's Quick Disconnect into the phone's modular headset port, with no external amplifier. Direct connection puts volume and mute control on the phone rather than on the cord — if you want inline controls plus Clearline audio enhancement, an amplifier is the better route.
Alternative. If your phone has no dedicated headset port, the PW720 won't work on its own — you'll want the HW720 with an M22 amplifier instead. For a single-ear premium version, see the PW710; for the lower-priced 500-series Polaris headsets, see the PW510, PW520, PW530, and PW540.
FAQ
Frequently Asked Questions
The Plantronics PW720 is the premium EncorePro HW720 binaural noise-canceling headset bundled with the A10 direct-connect cable. It covers both ears and plugs straight into a headset-ready phone's built-in amplified port, so no separate amplifier is needed. "Polaris" refers to that direct-connect method — it's the modern replacement for Plantronics' discontinued P-series Polaris headsets.
Choose the PW720 if agents work on a noisy floor and need both ears covered to focus and block the room. Choose the PW710 if they need to stay aware of colleagues or a supervisor, since its single earpiece leaves one ear open. Both are premium Polaris headsets with the A10 cable — both ears versus one is the only real difference.
No. The PW720 is the direct-connect version — it includes the A10 cable and plugs into a phone that already has a built-in amplified headset port, so no external amplifier is required. If your phone has no headset port, or you want inline volume and mute, you'd need the HW720 with an M22 amplifier instead.
The PW720 works with headset-ready phones that have a built-in amplifier — Nortel (Norstar and Meridian), NEC, Toshiba, Mitel, Aastra, 3COM, Comdial, ESI, and SciTec, among others. It does not work with Cisco phones or systems that require a specific HIS, HIC, or U10 cable. Confirm your phone model first, since the wrong cable is the most common cause of returns.
The PW720 was formerly the PW301N, the Polaris version of the headset now known as the HW720 (itself formerly the HW301N). It's the same premium binaural headset and direct-connect solution under current naming, so if you need a "PW301N" replacement, the PW720 is it.
