Plantronics HW540 Convertible Wired Headset
The Plantronics HW540 is a convertible wired headset engineered for professionals who spend hours on calls every day. We designed this model to give you three wearing options — over-the-head, over-the-ear, and behind-the-neck — so you can switch styles mid-shift without swapping hardware. The noise-canceling microphone filters out background chatter up to 18 dB, ensuring your voice comes through clearly even in open-plan environments.
Our quick-disconnect feature lets you walk away from your desk without removing the headset, and the reinforced cable withstands years of daily use. Whether you’re managing customer service queues or navigating back-to-back conference calls, the HW540 adapts to your workflow without compromise.
- Three convertible wearing styles in one headset
- Noise-canceling microphone with 18 dB ambient reduction
- Quick-disconnect cable for desk mobility
- Reinforced strain relief and Kevlar-wrapped cord
- Compatible with Plantronics amplifiers and direct-connect desk phones
Convertible wearing styles for every preference
The HW540 ships with three distinct headband configurations in the box. Our over-the-head style distributes weight evenly across the crown, ideal for users who wear glasses or prefer traditional stability. The over-the-ear hook wraps around a single ear for a more discreet profile, while the behind-the-neck band keeps hair and accessories clear.
You can swap between styles in under thirty seconds without tools. Each configuration uses the same speaker and microphone assembly, so audio quality remains consistent regardless of how you wear it. We include all three headbands as standard, not as add-on accessories.
Noise-canceling microphone engineering
Our proprietary microphone boom uses a dual-layer acoustic chamber to isolate your voice from ambient noise. Testing shows the HW540 reduces background sound by 18 decibels compared to omnidirectional designs, which translates to fewer repeated questions and clearer client interactions.
The boom arm rotates 300 degrees and locks into position with a friction hinge. You can position the mic precisely at the corner of your mouth for optimal pickup, then tuck it away when you step off a call. The windscreen foam is replaceable and washable, maintaining hygiene standards in shared-desk environments.
Quick-disconnect mobility and cord durability
We built the HW540 with a quick-disconnect (QD) jack that separates the headset from the lower cable in one motion. This lets you stand, walk to the printer, or grab files without unplugging from your phone system or removing the headset from your head. The lower cable remains connected to your amplifier or desk phone base.
The cord itself is wrapped in Kevlar fiber and rated for 100,000 flex cycles. Strain relief boots at both the QD junction and the amplifier connector prevent the most common failure points. Plantronics wired headsets in this series share the same reinforced cable architecture, so replacement parts interchange across models when needed.

What people are saying
Common questions about the HW540 headset
The HW540 is designed primarily for desk phone systems and requires a Plantronics amplifier (like the M22 or MX10) or a direct-connect adapter cable. It uses an analog quick-disconnect plug, not USB. For computer use, pair it with our DA series USB amplifiers to bridge the headset with softphone applications.
Yes. We include all three headband configurations — over-the-head, over-the-ear, and behind-the-neck — in every HW540 box at no additional cost. You swap styles by sliding the speaker assembly off one headband and onto another, which takes about 20 seconds and requires no tools.
All three models use the same noise-canceling microphone capsule with 18 dB ambient sound reduction. The difference lies in wearing style and speaker configuration. The HW510 offers only the over-the-head band, the HW520 is binaural (dual speakers), and the HW540 is monaural but convertible across three wearing options.
The lower cable (from the quick-disconnect to the amplifier) measures approximately 10 feet. You can extend reach by using a longer coiled cord between your amplifier and desk phone base, but we do not recommend splicing or adding inline extensions to the headset cable itself, as this can degrade audio quality and void the warranty.
The leatherette cushion is user-replaceable and snaps onto the speaker housing without adhesive. In high-use call center environments, we recommend replacing it every six months to maintain hygiene and acoustic seal. Replacement cushions are sold separately as part number 64394-01.
Yes, as long as your amplifier has a quick-disconnect (QD) port. The HW540 is compatible with all Plantronics amplifiers including the M22, MX10, P10, M12, and DA series. The quick-disconnect standard is consistent across our professional headset line, so legacy amplifiers and new headsets interchange freely.
Absolutely. The over-the-head and behind-the-neck styles are designed to avoid interference with eyeglass temples. The over-the-ear hook may press slightly against thick frames, but most users find it comfortable. The lightweight 21-gram design minimizes pressure points regardless of wearing style.
