HP Poly Mission 425 Stereo Wired Headset Bulk USB-C & USB-A Leatherette

The HP Poly Mission 425 Stereo USB Wired Headset in leatherette is the sweet spot of the Mission 400 series - all the professional audio technology of the 425, paired with soft leatherette ear cushions that deliver a better passive seal, improved all-day comfort, and a more premium feel than the foam Classic version.

If you spend your working day on calls, comfort is not a luxury. It is a productivity requirement. The leatherette cushions on this version conform gently to the ear, creating a passive acoustic seal that reduces ambient sound reaching the speakers - adding a layer of natural noise isolation on top of the electronic AI noise filtering. After hours of back-to-back calls, that difference is felt.

At the core of the Mission 425 is a noise-cancelling microphone with AI Noise Reduction - continuously filtering ambient background sounds so only your voice reaches the other end of the call. No manual muting every time a colleague speaks nearby. No apologising for background noise. Just clear, professional, focused conversations from the first call of the day to the last.

Super wideband audio and 32mm speaker drivers reproduce voice detail and tone with natural breadth, making calls feel closer to face-to-face conversations and reducing the listening fatigue that builds up during long call sessions.

HP Poly SoundGuard Digital runs in the background throughout your day, protecting your hearing on three simultaneous levels - controlling sudden audio spikes, applying an advanced audio limiter, and managing your cumulative Average Daily Noise Exposure. Your hearing stays protected from eight in the morning to five in the afternoon, without any impact on audio quality.

Connect via USB-C with the tethered USB-A adapter included, and the Mission 425 is ready in seconds - no drivers, no software, no configuration. Certified for Microsoft Teams, Zoom, Google Meet, and compatible with Windows, macOS, Chrome OS, Android, and iOS straight out of the box.

This is the Bulk packaging version - ideal for enterprise, contact centre, and IT procurement where efficient, high-volume deployment matters. Same headset, same full specifications, same two-year warranty - leaner packaging, lower cost per unit.

Professional audio. Leatherette comfort. Ready the moment you need it.

KEY FEATURES

AI Noise Reduction - Background Filtering on Every CallThe Mission 425 is equipped with a noise-cancelling microphone enhanced by AI Noise Reduction that continuously identifies and removes ambient sounds from your environment before your voice is transmitted. Office chatter, keyboard noise, air conditioning, and background activity are filtered out automatically throughout every call - without any manual muting required. Only your voice comes through, consistently clean and professional.

Super Wideband Audio - Natural, Fatigue-Reducing SoundSuper wideband audio captures a broader frequency range than standard headsets, reproducing voice detail, tone, and nuance more naturally. Calls feel closer to face-to-face conversations. Extended sessions become less draining, comprehension improves, and communication quality stays high through the longest working days.

32mm Speaker Drivers - Rich, Clear AudioLarge 32mm speaker drivers deliver richer, more detailed audio that makes voices easier to distinguish and understand - reducing cognitive load during multi-participant calls and extended listening sessions. Improved clarity means less effort spent straining to hear and more energy invested in the actual conversation.

Leatherette Ear Cushions - Comfort and Passive Isolation CombinedThe leatherette cushions on this version of the Mission 425 deliver two benefits that the foam Classic cannot match. First, leatherette is softer and more accommodating against the skin during extended wear - it does not compress and harden the way foam does over time. Second, the leatherette material creates a gentle passive acoustic seal around the ear, naturally attenuating ambient sound before it reaches the speaker. This layered approach - passive isolation from the cushion seal plus active AI filtering from the microphone - means the Mission 425 Leatherette performs better in noisy environments than the foam Classic version, even with identical electronic components.

290-Degree Rotating Boom Microphone with Raise-to-MuteThe boom microphone rotates 290 degrees, allowing comfortable positioning on either the left or right side. Raising the boom arm upward activates automatic mute - an instant, intuitive gesture that requires no button press and no screen interaction. Lower the boom back to position and you are live again. Voice prompts confirm mute on, mute off, volume maximum, and volume minimum so you always know your status.

SoundGuard Digital - Multi-Layer All-Day Hearing ProtectionHP Poly SoundGuard Digital operates on three simultaneous protection levels throughout your entire working day. G616 anti-startle protection limits sudden audio spikes to below 102 dB SPL, compliant with the international ACIF G616 standard. An Advanced Audio Limiter provides an additional protection threshold. Average Daily Noise Exposure management monitors your cumulative sound exposure and keeps it within 80 dBA or 85 dBA time-weighted average limits. Default acoustic shock protection limits all sounds to below 118 dBA at all times without any configuration. The full SoundGuard Digital feature set is activated via the HP Poly Studio App.

Intuitive Inline Controls with Teams IlluminationThe inline controller puts full call management on the cable - mute and unmute, volume up and down, answer and end calls, access Microsoft Teams. The Microsoft Teams button on the controller illuminates with the Teams icon when you are on a Teams call, giving you clear visual call status at a glance without looking at your screen.

Plug & Play USB-C with Tethered USB-A AdapterConnect via the USB-C cable with the included tethered USB-C to USB-A adapter and the Mission 425 works immediately on any laptop, desktop, or workstation. No drivers, no software installation, no IT configuration required. Plug in and your call is ready in seconds. The 2-metre cable provides generous freedom of movement at your workstation.

Microsoft Teams Certified - and Compatible with Zoom, Google Meet & MoreThe Mission 425 Leatherette is certified for Microsoft Teams with a dedicated Teams button on the inline controller. It also works seamlessly with Zoom, Google Meet, Cisco Webex, and all major UC platforms. One SKU covers both standard UC and Teams environments - no separate model required for each platform.

Supports Stereo and Monoaural Wearing StylesThe Mission 425 supports both full stereo wearing - both ear cups in position - and monoaural wearing, with one ear cup folded back for single-ear listening. Useful for users who prefer to keep one ear open to their physical environment, or who need situational awareness in shared workspaces.

HP Poly Studio App - Personalise Your ExperienceThe HP Poly Studio App allows users to personalise EQ settings, configure call preferences, and activate the full SoundGuard Digital feature set. Firmware updates are delivered through the app, keeping the headset current over time.

HP Poly Lens Admin Cloud - Enterprise Fleet ManagementIT administrators can remotely deploy, configure, monitor, and update large fleets of Mission 425 units from a single cloud-based platform using HP Poly Lens Admin Cloud - eliminating per-workstation IT visits and dramatically reducing deployment time and overhead for organisations equipping multiple teams.

Replaceable Ear Cushions - Long-Term ValueThe leatherette ear cushions are replaceable, available as accessories sold separately. Refreshing worn cushions extends the useful life of the headset significantly and maintains both comfort performance and acoustic seal quality - reducing total cost of ownership over time.

Bulk Packaging - Efficient Enterprise DeploymentThis is the Bulk packaging version (SKU: C01B6A6). Bulk packaging eliminates individual retail boxes, reducing per-unit cost and packaging waste - making it the preferred choice for contact centre, enterprise, and IT procurement of ten units or more. The headset, all included accessories, and the full two-year warranty are identical to the individually packaged retail version.

TCO 10 Certified and Sustainably BuiltThe HP Poly Mission 425 is TCO 10 certified - independently verified against comprehensive environmental and social responsibility criteria across the product lifecycle. Manufactured using at least 30% post-consumer recycled plastic and shipped in paper-based packaging, supporting responsible procurement for organisations with ESG, green purchasing, or sustainability reporting commitments.

2-Year Poly Standard WarrantyBacked by the Poly standard two-year limited warranty - the same warranty applies to both Bulk and individually packaged versions.

FREQUENTLY ASKED QUESTIONS

Q: What is the difference between the Mission 425 Leatherette and the Mission 425 Classic?

A: The core difference is the ear cushion. The Classic version uses foam cushions and weighs 126g. This Leatherette version uses soft oblong leatherette cushions and weighs 132g. The leatherette cushions offer two advantages over foam: they are more comfortable against the skin over extended periods - they do not compress and harden the way foam does during long wearing sessions - and they create a better passive acoustic seal around the ear, naturally reducing ambient noise before it reaches the speaker. Both versions share the same audio technology, AI Noise Reduction microphone, SoundGuard Digital, super wideband audio, 32mm speakers, inline controls, USB connectivity, Teams certification, and TCO 10 certification. The choice between them is primarily about comfort preference and how important passive noise isolation is for your specific work environment.

Q: What is the difference between the Mission 425 Leatherette and the Mission 625?

A: The Mission 625 is the next tier up in the HP Poly Mission series and includes several features the 425 does not have. The 625 features two noise-cancelling microphones with AI Noise Reduction, versus a single microphone on the 425 - providing more effective dual-mic voice capture and better background noise filtering. The 625 includes a 360-degree busylight integrated into both earcups that illuminates red during calls, which the 425 does not have. The 625 features a padded headband pad and plush memory foam earcups - a more premium comfort configuration than the leatherette-only cushions on the 425. The 625 also includes a carrying case and carries Microsoft Open Office Certification, specific to loud environments. Both share the same SoundGuard Digital, super wideband audio, 32mm speakers, USB-C and USB-A connectivity, Teams certification, and TCO 10 certification. The Mission 425 Leatherette Bulk is the better-value choice for standard office and hybrid environments; the 625 is the right choice for contact centres and high-noise open-plan environments where busylight visibility, dual-mic performance, and memory foam endurance are important.

Q: Why does leatherette provide better noise isolation than foam?

A: Leatherette creates a firmer, more consistent seal against the surface of the ear than open-cell foam. Foam cushions are porous and compressible - they allow some sound to pass through the cushion material itself, and their seal degrades as they compress during extended wear. Leatherette is a denser, non-porous material that forms a more effective passive barrier between the speaker and the outside environment. Combined with the AI Noise Reduction processing on the microphone, the leatherette seal on the Mission 425 provides a two-layer noise management approach that the foam Classic does not.

Q: What is AI Noise Reduction and how does it work?

A: AI Noise Reduction is an active microphone processing technology that continuously analyses the audio captured by the boom microphone in real time, identifies non-speech background sounds, and removes them before your voice is transmitted on a call. Ambient noise from your surroundings - office conversations, keyboard sounds, air conditioning, traffic - is detected and filtered out automatically throughout the call. You do not need to manually mute between sentences. Only your voice passes through to the other person, cleanly and consistently.

Q: Does the boom arm automatically mute when raised?

A: Yes. Raising the boom arm upward activates automatic mute - the microphone silences instantly without any button press. Lowering it back into position restores the active microphone. Voice prompts confirm mute on and mute off so you are always certain of your status, and the inline controller also provides a dedicated mute button for manual control.

Q: Does the Mission 425 work with both USB-C and USB-A ports?

A: Yes. The Mission 425 Leatherette Bulk connects via USB-C with a tethered USB-C to USB-A adapter included in the box. This provides compatibility with any laptop, desktop, or workstation regardless of available ports - modern USB-C ports directly, and legacy USB-A ports via the adapter - with no additional accessories required.

Q: Does the headset require any software or drivers?

A: No drivers or software are required for standard operation. The Mission 425 functions as a plug-and-play USB audio device on Windows 11, macOS, Chrome OS, Android, and iOS. The HP Poly Studio App is optional, used for personalising audio settings, adjusting preferences, and activating the full SoundGuard Digital feature set. IT teams can use HP Poly Lens Admin Cloud for fleet management, but this is not required for individual use.

Q: Is the Mission 425 Leatherette certified for Microsoft Teams?

A: Yes. The Mission 425 Leatherette is certified for Microsoft Teams. A dedicated Teams button on the inline controller illuminates with the Teams icon when you are on a Teams call, and provides one-touch access to Teams functionality. One SKU supports both standard UC platforms and Teams without any separate model - simplifying procurement and deployment.

Q: What is SoundGuard Digital?

A: SoundGuard Digital is HP Poly's comprehensive acoustic protection system, operating simultaneously on three levels. G616 anti-startle protection limits sudden loud audio spikes - such as feedback, accidental volume surges, or unexpected loud noises - to below 102 dB SPL, compliant with the ACIF G616 international standard. An Advanced Audio Limiter adds a further protection threshold. Average Daily Noise Exposure management monitors your cumulative sound exposure across the working day and controls output to keep it within 80 dBA or 85 dBA time-weighted average. Basic acoustic shock protection always limits all sounds to below 118 dBA by default without configuration. Full SoundGuard Digital activation requires the HP Poly Studio App.

Q: Is the headset comfortable for all-day and contact centre wear?

A: Yes. At 132 grams the Mission 425 Leatherette is lightweight for a professional stereo headset. The oblong leatherette cushions are shaped to sit comfortably on the ear without creating pressure concentration points, and the leatherette material remains soft against the skin through extended sessions in a way that compressed foam does not. The adjustable headband distributes weight evenly across the top of the head. For contact centre agents and professionals spending multiple hours daily on calls, the leatherette version is meaningfully more comfortable over a full shift than the foam Classic version.

Q: What is the difference between the Bulk version and the retail version?

A: The Bulk version (SKU C01B6A6) contains the identical headset with the same full specifications, accessories, and two-year warranty as the individually boxed retail version. The only difference is packaging - Bulk removes the individual retail box, reducing per-unit cost and packaging waste. For enterprise and contact centre procurement where tens or hundreds of units are being deployed, Bulk packaging delivers better value without any reduction in product quality or warranty coverage.

Q: Are the ear cushions replaceable?

A: Yes. The leatherette ear cushions on the Mission 425 are replaceable, available as separate accessories. Replacing cushions as they age extends the useful life of the headset considerably and maintains both the comfort quality and the passive acoustic seal performance of fresh cushions - reducing total cost of ownership for long-term and large-scale deployments.

Q: Can IT teams manage the Mission 425 Leatherette remotely?

A: Yes. HP Poly Lens Admin Cloud provides IT administrators with a centralised cloud-based platform for remotely deploying, configuring, monitoring, and updating Mission 425 fleets at scale. Manage one device or thousands from a single interface, eliminating the need to configure each workstation individually. Individual users can personalise their experience and enable SoundGuard Digital features via the HP Poly Studio App.

Q: What sustainability credentials does the Mission 425 hold?

A: The Mission 425 Leatherette Bulk is TCO 10 certified - the current generation of the internationally recognised, independently verified TCO sustainability label for IT products. It is manufactured using at least 30% post-consumer recycled plastic as a proportion of total plastic content, and is shipped in paper-based packaging. TCO 10 covers environmental, social responsibility, hazardous substance, and product safety criteria - all verified by an independent third-party auditor.

Q: What warranty does the HP Poly Mission 425 Leatherette Bulk come with?

A: The Poly standard two-year limited warranty applies - identical to the individually packaged retail version. Bulk packaging does not affect warranty coverage.
