The Plantronics EncorePro HW520 answers that by covering both ears, so the room drops away and the call is all that's left. It's the binaural version of the HW510, and like the HW510, it comes in a version for whatever phone is on your desk.\u003c\/p\u003e\n\n\u003cp\u003eBoth ears or one is a real choice, not just an upgrade — and so is which cable you need. Here's how to land on the exact EncorePro HW520 for your floor.\u003c\/p\u003e\n\n\u003ch2\u003eBoth ears or one? The EncorePro HW520 vs the HW510\u003c\/h2\u003e\n\n\u003cp\u003eThe EncorePro HW520 is binaural — it covers both ears — where the HW510 covers one. Both ears mean more focus and better isolation on a noisy floor; one ear open means an agent can still hear a colleague or supervisor. Neither is simply better; it depends on whether the job needs concentration or room awareness.\u003c\/p\u003e\n\n[compare]\n\u003cdiv\u003e\n\u003cstrong\u003eHW520 — binaural (both ears)\u003c\/strong\u003e\u003cbr\u003eBlocks more of the room for focus and accuracy. Best for noisy, open-plan floors and agents who need to shut the room out.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eHW510 — mono (one ear)\u003c\/strong\u003e\u003cbr\u003eOne ear open for the floor. Best where agents collaborate, or need to stay tuned to a supervisor or nearby colleagues.\u003c\/div\u003e\n[\/compare]\n\n\u003cp\u003eThere's a floor-wide effect, too: when everyone's wearing both-ear headsets, the whole room gets quieter, because agents stop raising their voices to hear over each other.\u003c\/p\u003e\n\n[callout type=\"info\"]One thing the \"dual-ear\" label gets wrong: the EncorePro HW520 is binaural, not stereo. Both speakers play the same voice signal — it's built for focus, not music. True stereo headsets carry separate left and right channels; the HW520 deliberately doesn't, because a phone call is one channel and the goal is clarity in both ears.[\/callout]\n\n\u003ch2\u003eBuild the exact EncorePro HW520 you need\u003c\/h2\u003e\n\n\u003cp\u003eSeven versions, differing along two questions: noise-canceling mic or voice tube, and how it connects to your phone.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe microphone — almost everyone wants noise-canceling.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e[icon:headset-stereo] Noise-canceling (HW520).\u003c\/strong\u003e The standard choice, used by six of the seven versions.

The phone-specific bundles — Avaya, Cisco, Cisco SPA, Polycom, and Yealink — include the certified cable for that phone and plug straight into its headset port, no amplifier needed. The universal QD version includes no cable: its standard 4-pin Quick Disconnect needs a Plantronics M22 amplifier, a direct-connect bottom cable, or a DA-series USB adapter for softphones, bought separately.\u003c\/p\u003e\n\n[callout type=\"honest\"]The most common HW520 ordering mistake: buying the universal QD version expecting it to plug into a desk phone or a USB port on its own. It doesn't — it needs an amplifier or the right cable. If you know your phone, the matching bundle is the simpler buy, with the certified cable already in the box. For a computer or softphone, add a Poly DA-series USB adapter such as the DA80. Not sure which you need? Call us with your phone or softphone and we'll match it.[\/callout]\n\n\u003ch3\u003eBuilt for the long shift\u003c\/h3\u003e\n\n\u003cp\u003eEvery version is built the same way: aircraft-grade aluminum with laser-welded construction and metal joints, soft replaceable ear cushions, and an adjustable headband. The binaural design uses a single cable — the second speaker is fed by a flat ribbon hidden inside the headband, so there's no cable splitting under your chin. The flexible boom has click-stop positioning guides that tell your fingers when the mic is placed right. For more isolation, the HW520 also takes circumaural (around-the-ear) leatherette cushions in place of the standard on-ear foam. It replaces the older HW261N.\u003c\/p\u003e\n\n\u003ch3\u003eHearing protection, HAC, and audio\u003c\/h3\u003e\n\n\u003cp\u003eThe EncorePro HW520 uses SoundGuard acoustic limiting to cap sudden noise spikes above 118 dBA, which helps a contact center meet OSHA and Noise at Work requirements over long shifts. It's telecoil hearing aid compatible for agents who use a T-coil-equipped aid, and its wideband audio reaches up to 6,800 Hz for richer, clearer calls that reduce listening fatigue. Pick the connection that matches your desk today, and you've got a both-ears headset built to outlast the phone it's plugged into.\u003c\/p\u003e\n\n\u003cdiv data-tab=\"whats-in-the-box\"\u003e\n\u003cul\u003e\n  \u003cli\u003ePlantronics EncorePro HW520 binaural headset with Quick Disconnect (or HW520V with voice tube)\u003c\/li\u003e\n  \u003cli\u003eSoft foam ear cushions (fitted, both ears)\u003c\/li\u003e\n  \u003cli\u003eQuick start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat else is in the box depends on the version: the Avaya, Cisco, Cisco SPA, Polycom, and Yealink bundles add the certified adapter cable for that phone, so there's nothing more to buy.
