Plantronics EncorePro HW540 Convertible Headset
The EncorePro HW540 gives you three wearing options in one professional headset: over-the-head, over-the-ear, or behind-the-neck. Built for contact centers, help desks, and offices that demand crystal-clear conversations, the HW540 pairs our signature noise-canceling microphone with lightweight materials that won't fatigue after hours of continuous use.
We designed this headset to withstand the rigors of shift work—reinforced cables, a flexible boom arm, and replaceable ear cushions mean your investment lasts through years of daily calls. Quick-disconnect functionality lets you walk away from your desk without removing the headset, and the acoustic limiting technology protects your hearing during unexpected volume spikes.
Performance & design highlights
Convertible wearing styles for personal preference
The HW540 ships with all three attachment options in the box, so your team can choose the fit that works best for their comfort and hairstyle. The over-the-head band distributes weight evenly across the crown, while the over-the-ear hook tucks behind one ear without disturbing hair or glasses. The behind-the-neck neckband rests at the base of your skull and works especially well under caps or headwear.
Every wearing style uses the same monaural speaker and microphone boom, so audio quality stays identical no matter which attachment you select. Switching between styles takes seconds—remove the current attachment, snap the new one into place, and adjust the ear cushion height to your preference.
Noise-canceling microphone technology
Our engineers positioned the HW540’s microphone capsule to capture your voice while filtering out ambient office noise. The cardioid pickup pattern focuses on sound directly in front of the mic and rejects noise from the sides and rear, reducing background conversations, keyboard clicks, and HVAC hum by as much as 75%.
The foam windscreen adds another layer of protection against plosive sounds and breath noise during extended calls. Both the windscreen and the flexible boom arm are replaceable components, so you can refresh them as they wear without replacing the entire headset.
Built for years of daily use
Reinforced cable construction
We reinforced the Plantronics HW540 cable jacket at stress points where most headsets fail—the quick-disconnect junction and the headband entry point. The cable itself uses stranded copper conductors that flex repeatedly without breaking, and the strain relief boots prevent sharp bends that would crack cheaper designs.
Replaceable soft goods
The leatherette ear cushion attaches with a simple twist-lock mechanism, so you can swap in a fresh cushion when the original shows wear. We also include a replacement foam windscreen in every box. Teams managing large deployments appreciate that these consumable parts cost far less than replacing entire headsets every year.

Common questions about the HW540 headset
The HW540 requires a Plantronics amplifier or direct-connect cable to interface with your desk phone. Most office phones with a standard headset jack work with our M22 or MX10 amplifier, which provide volume control and compatibility across virtually all major phone brands. If your phone has a built-in headset port, you may only need a direct-connect cable specific to your phone model.
For softphone or computer-based calling, pair the HW540 with a Plantronics USB adapter like the DA80 or DA70. The headset's quick-disconnect plug makes it easy to swap between phone and PC without removing the headset.
Yes, the HW540 ships with three wearing styles in the box: over-the-head, over-the-ear, and behind-the-neck. You can switch between them in seconds by removing the current attachment and snapping a different one into place. All three styles use the same speaker and microphone, so audio quality and noise canceling remain identical regardless of which option you choose.
The over-the-ear hook is especially popular with agents who wear glasses or prefer not to disturb their hairstyle. The neckband works well if you wear a hat or headwear during your shift.
Our noise-canceling microphone reduces background office noise by up to 75 percent compared to non-canceling designs. The cardioid pickup pattern focuses on your voice directly in front of the mic while rejecting sound from the sides and rear, so keyboard clicks, nearby conversations, and HVAC noise are significantly suppressed.
The foam windscreen adds further protection against plosive sounds and breath noise. Callers on the other end hear your voice clearly even when your office environment is busy or loud.
The HW540 uses replaceable leatherette ear cushions that twist off and snap back on without tools. We include one replacement cushion in every box, and additional cushions are available separately. The foam windscreen that covers the microphone is also replaceable—it protects the mic capsule from moisture and debris over time.
The flexible boom arm and cable strain relief are designed to last the life of the headset, but if damage occurs, those components can be serviced through our support channel. This modular approach keeps your total cost of ownership low compared to discarding entire headsets when a single part wears out.
Yes, the HW540 includes SoundGuard technology that monitors incoming audio and limits sudden loud sounds to safe levels. The system cuts off transient spikes that exceed 118 dBA before they reach your ear, protecting you from equipment malfunctions, line feedback, or accidental key presses that could cause hearing damage.
This protection runs continuously without affecting normal conversation volume or clarity. For organizations managing OSHA compliance or employee safety programs, this feature reduces liability and safeguards team members who spend extended hours on calls daily.
With proper care, the HW540 routinely lasts three to five years in high-volume call center deployments. The reinforced cable construction at stress points—especially the quick-disconnect junction and headband entry—prevents the premature failures common in cheaper headsets. Replacing ear cushions and windscreens as they wear extends the headset's usable life significantly.
Many organizations budget for cushion replacement every twelve to eighteen months depending on shift intensity, but the core headset components hold up well beyond that window. Quick-disconnect functionality also reduces cable strain since agents can unplug and walk away without removing the headset or twisting the cord.
Yes, the quick-disconnect plug on the HW540 lets you unplug from your amplifier or phone system and walk away while keeping the headset on your head. When you return to your desk, snap the plug back into the amplifier socket and resume your call or start a new one instantly.
This feature requires a compatible Plantronics amplifier or bottom cable with a QD socket. The disconnect happens at the amplifier end, not at the headset itself, so the headset stays securely attached to your head while you move around the office.
