Plantronics PW710 Polaris Premium Mono Noise-Canceling Headset (HW710 + A10)
The PW710 is premium, and skips the amplifier
Premium headsets and amplifier boxes usually arrive together — you spend up for the leatherette and the satin finish, then add a powered amplifier at every desk. The Plantronics PW710 Polaris headset breaks that pairing. It's the top-tier EncorePro HW710 — leatherette pads, nylon-composite frame, 53 grams — packaged to plug straight into a headset-ready phone, with no separate amplifier.
The PW710 is the EncorePro HW710 premium noise-canceling headset bundled with the Plantronics A10 direct-connect cable. If your phones already have built-in amplifiers, it's the most comfortable headset in the wired line with nothing extra to power or place on the desk.
Premium comfort, no box on the desk
The PW710 is the premium member of the Polaris family, where the others are built on the workhorse 500-series headsets. Its leatherette ear pads slide over hair cleanly where foam tends to snag, the satin-finish nylon-composite frame keeps it to 53 grams, and the telescoping, pivoting boom extends and rotates into precise position, then sits low and clear of your peripheral vision. It's the headset you put on people who wear one all day, or who are client-facing and seen.
Premium where it shows, simple where it counts
The HW710 is the comfort tier Poly builds to reward top performers — and the Polaris version keeps that comfort while removing the amplifier from the equation. For a reception desk, an executive assistant, or a premium-brand floor running headset-ready phones, the PW710 gives the polished look and all-day leatherette comfort without a powered box cluttering the desk or the budget. Premium where the wearer feels it, simple where IT deploys it.Direct-connect: no amplifier per seat
The PW710 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 HW710-plus-A10 combination is the modern equivalent.
The HW710 inside
The headset itself is the EncorePro HW710 — formerly the HW291N — the premium 700-series mono headset: plush leatherette ear pads over an ultra-light nylon-composite frame, a reinforced headband, a satin finish, and a telescoping noise-canceling boom. It runs wideband audio for crystal-clear calls, weighs about 53 grams, and is the comfort-and-looks step up from the 500-series PW510. Foam cushions are available if you prefer them, and both are replaceable.
The PW710 is the premium, no-amplifier answer for a headset-ready phone — the leatherette-and-satin HW710 and the A10 cable, matched and ready, with nothing to power and nothing extra on the desk. Confirm your phone takes a direct-connect cable, and it's the most comfortable plug-and-go headset in the wired line, backed by HeadsetPlus's lifetime support.

Phones. The PW710 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 HW710'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 PW710 won't work on its own — you'll want the HW710 with an M22 amplifier instead. For the 500-series Polaris headsets at a lower price, see the PW510, PW520, PW530, and PW540.
FAQ
Frequently Asked Questions
The Plantronics PW710 is the premium EncorePro HW710 mono noise-canceling headset bundled with the A10 direct-connect cable. It 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.
No. The PW710 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 HW710 with an M22 amplifier instead.
The PW710 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 PW710 is built on the EncorePro HW710, the premium 700-series headset: leatherette ear pads, an ultra-light nylon-composite satin-finish frame at 53 grams, and a telescoping boom. The other Polaris headsets — PW510, PW520, PW530, PW540 — use the 500-series build with foam cushions at a lower price. Choose the PW710 for all-day comfort and a polished look.
The PW710 was formerly the PW291N, the Polaris version of the headset now known as the HW710 (itself formerly the HW291N). It's the same premium headset and direct-connect solution under current naming, so if you need a "PW291N" replacement, the PW710 is it.
