EPOS Sennheiser SD Pro 2 Wireless Binaural Headset - Microsoft Certified

An office running Skype for Business or Lync — and some still are, on-premises — doesn't have many current headset options built specifically for it. The EPOS Sennheiser SD Pro 2 wireless headset is one of the few, a dual-connectivity DECT headset for desk phone and softphone that was purpose-certified for Microsoft's Lync and Skype for Business platforms.

It's a double-sided, binaural design with the same core hardware as the Sennheiser DW Pro 2 sold in Europe — a newer base is the only real difference between the two. If your organization migrated to Teams years ago, this isn't the certified headset for that platform; it's built for the Microsoft UC generation that came before it.

Do you need a handset lifter?

One real decision before checkout: how you want to answer desk phone calls when you're away from your desk.

• Headset only. Answer with a button press at your desk — the desk phone handset stays untouched.
• Add an HSL10 handset lifter or TCI 01 electronic hook-switch interface (sold separately). Either lets you answer remotely without touching the phone. Compatibility depends on your desk phone model, so call ahead to confirm which one you need.

What "MS Teams Certified" actually means for this headset

The EPOS Sennheiser SD Pro 2 wireless headset is certified for Microsoft Lync and Skype for Business — not Microsoft Teams. The "ML" in its name reflects that Lync-era certification. If your team runs Teams, this headset will likely still function over its USB softphone connection, but it doesn't carry Teams-specific certification, and Microsoft retired Skype for Business Online in 2021. This is the right headset for an organization still running Skype for Business Server on-premises, or one that simply needs solid dual-connectivity DECT hardware and doesn't need a Teams-specific badge.

Dual connectivity: desk phone and softphone, one touch to switch

A single button on the base switches between your desk phone and your computer's softphone connection, with the included USB cable handling the PC side. Up to four EPOS Sennheiser SD Pro 2 headsets can pair to one base for conference calls or hot desking, letting different people share the same base station across shifts or desks.

Range, battery, and call quality

The EPOS Sennheiser SD Pro 2 wireless headset reaches up to 590 ft (180m) line of sight, dropping to a real 180 ft (55m) in a typical office once walls and cubicles are factored in — DECT's protected frequency band means it won't compete with office Wi-Fi. Talk time runs up to 12 hours in narrowband mode or up to 8 hours in wideband mode, with fast charging delivering 50% battery in just 20 minutes.

Voice clarity and hearing protection

An ultra noise-canceling microphone paired with Digital Signal Processing keeps your voice clear on the caller's end, even in a busier office environment. ActiveGard technology protects your hearing from sudden volume spikes on the line — a sudden loud noise or bad connection won't hit your ear at full force. Extra-soft leatherette ear cushions and an adjustable headband are built for full-day wear.

This is a headset for an organization with a specific, real need: dual desk phone and softphone connectivity, built on genuinely long DECT range, without paying for a Teams certification that a Skype for Business or Lync environment doesn't need. If that's your setup, it's dependable, proven hardware — just go in knowing exactly which Microsoft platform it was actually built for.
