EPOS IMPACT 400 Wireless: Teams-Certified Bluetooth Headset Specs, Pricing and IT Buyer Checks

What was announced​

EPOS says the IMPACT 400 Wireless is certified for Microsoft Teams with "Premium Microphone for Open Office." The Copenhagen release is dated October 6, 2026. It calls the headset the newest member of the IMPACT 400 Series.

It joins the wired IMPACT 400 and IMPACT 400 ANC. EPOS says IT teams can pick wired or wireless connectivity and a noise-control level while staying within one headset family.

The same release has been republished by outlets including The Manila Times and TechBuzz Ireland. Those copies carry the same announcement, so they are not independent confirmation.

Key specifications (all EPOS-stated)​

• Design: a double-sided, on-ear headset weighing 145 grams. It has breathable leatherette ear pads and a fold-flat design.
• Boom microphone: it can be worn on either side. EPOS says it uses AI-based noise reduction and has a mute-status LED. Lowering the boom answers or unmutes a call, and raising it mutes.
• Connectivity: Bluetooth 6.0, Bluetooth Low Energy Audio and the LC3 codec. Multipoint supports two simultaneous Bluetooth connections, such as a PC and a phone.
• In the box: a BTD 400c USB-C Bluetooth dongle and a USB-C-to-USB-A adapter. That covers both modern and legacy PC ports.
• Range: up to 98 feet (30 meters). EPOS's footnote says real range varies with obstructions, interference and connected devices.
• Battery: up to 39 hours of talk time with ANC and the busy light on, or 47 hours with ANC off. Listening time is up to 63 hours with ANC on and 110 hours with ANC off. A 20-minute fast charge gives up to 12 hours of talk time, and a full cable charge takes about two hours.
• Serviceability: the ear pads and the battery are replaceable, and EPOS says the battery needs no tools to swap.
• Management: EPOS Connect handles firmware updates and personal audio settings. EPOS Manager gives administrators centralized configuration and management.

How to read the 99% claim​

The 99% figure is the claim most likely to be misread. EPOS says third-party lab testing followed the Microsoft Azure Speech Test Specification. The footnote gives the conditions:

• The headset sat on a head-and-torso simulator.
• English speech played at 89 dB SPL at the mouth reference point.
• Surrounding noise played at 70 dBA.
• EPOS adds that real-world results may vary.

That makes it a vendor-reported lab result under fixed conditions. It is not a Microsoft endorsement, and it does not predict transcription accuracy on your team's calls. EPOS also says cleaner voice input can help AI agents and AI-enabled workflows. That is a proposed benefit, and the release gives no separate test of it.

The battery numbers carry similar caveats. EPOS says they come from internal testing on headset firmware 0.2.79 and dongle firmware 0.2.38, at volume level 30 under laboratory conditions. Real battery life will vary with settings, usage and battery age.

Teams certification: what it does and doesn't tell you​

The "Premium Microphone for Open Office" label comes from Microsoft's Teams certification program. EPOS's existing IMPACT 400 page describes the label as a test of how well a headset handles noise from different directions and distances. That page is for the existing IMPACT 400 line, not the new wireless model.

Microsoft's public Teams device list had not been checked for this specific model when this article was prepared. A missing listing on launch day would not mean the headset is uncertified, since the announcement is only hours old. Still, an administrator should confirm the listing before buying at scale.

The release also lists certifications for Zoom Workplace and Call Center, Google Meet, and Webex by Cisco. Certification is not a guarantee of performance in every room, on every endpoint or with every app. The release does not describe behavior across operating systems or conferencing clients.

Fleet management: the open questions​

EPOS Manager is the part that matters most to admins. The release says it provides centralized tools for configuring and managing deployed devices. It does not say:

• which operating system versions are supported,
• what licensing applies,
• what deployment prerequisites exist,
• or which controls are available on this particular model.

Anyone planning a managed rollout on Windows should get those answers from EPOS before committing. That includes whether firmware updates can be pushed centrally or must be installed by each user through EPOS Connect.

Pricing and availability​

• US and Canada: planned for November 2026 at an MSRP of $219.99 excluding VAT. It is not on sale yet.
• UK: £169.99 excluding VAT.
• UK and EU: the release says pricing and availability will be confirmed by region.
• Warranty: two years, limited. The release points to Kensington's warranty page for terms. EPOS is part of ACCO Brands, which also owns Kensington.

Where it sits in the EPOS range​

EPOS calls this the high-value choice in its Bluetooth lineup. It places the IMPACT 500 and IMPACT 1000 above it. The IMPACT 1000 is described as adding adaptive ANC, wear detection, triple connectivity, incoming-speech clarity and wireless charging. This is manufacturer positioning, not an independent comparison.

Forbes contributor Mark Sparrow's coverage of the launch repeats the same core specifications and certifications, and describes the headset as mid-range. UC Advanced also covered the launch and echoes the release. None of that coverage amounts to hands-on testing.

Bottom line for IT buyers​

The IMPACT 400 Wireless adds a wireless option to a familiar enterprise headset family. On paper, the tool-free battery, replaceable ear pads and bundled USB-C and USB-A dongle options are sensible for large deployments.

Before buying, confirm these points:

1. The Microsoft Teams device listing for this exact model.
2. EPOS Manager's supported platforms, licensing and controls.
3. Real-world call quality in your noisiest spaces, ideally with a small pilot.
4. Regional pricing and availability outside the US and Canada.

Until independent reviews appear, treat the 99%, 39-hour and 98-foot figures as best-case manufacturer numbers.
