Sennheiser SC 60 USB ML Stereo Headset – Microsoft Teams Certified
The Sennheiser SC 60 solves a naming mystery
Look up a Sennheiser SC 60 and you'll see "ML" tacked onto the name with no explanation anywhere on the box. The Sennheiser SC 60 USB ML earned that suffix years ago when it was first certified for Microsoft Lync — the predecessor to Skype for Business, which itself gave way to Microsoft Teams — and the name simply never got updated as the certification did. It's the same badge, just with an older label still attached.
What it actually is: a wired, stereo USB headset built for people whose day runs on voice calls — Teams meetings, Skype for Business, customer support lines, dictation software. Both ears covered, a noise-canceling microphone on a bendable boom, wideband audio, and a two-year international warranty. Plug it into a USB-A port and Windows recognizes it immediately, with no drivers to install.
What does "ML" mean on the Sennheiser SC 60?
ML refers to the Sennheiser SC 60's original certification for Microsoft Lync, the unified communications platform that came before Skype for Business and, eventually, Microsoft Teams. The certification carried forward as the platform evolved — the Sennheiser SC 60 USB ML works with Teams today — but the naming convention stuck around unchanged, which is why the letters show up with no obvious meaning attached.
A badge that outlived its name
This happens more often than you'd think with long-running product lines. The certification underneath the ML badge kept pace with Microsoft's platform changes — Lync to Skype for Business to Teams — but Sennheiser never renamed the SKU. If you're buying today, treat "ML" as shorthand for "Microsoft-certified," not as a reference to a platform that no longer exists.Does the Sennheiser SC 60 block background noise?
Only on the way out. The Sennheiser SC 60's noise cancellation is microphone-side — it filters keyboard clatter, air conditioning hum, and nearby conversation out of your outgoing voice, so the person on the other end of the call hears you clearly. The ear cups themselves don't actively cancel incoming sound; the isolation you get from them is passive, just the physical seal of the cushion against your ear.
Also sold as the EPOS Impact SC 60
Sennheiser's enterprise headset division became EPOS through a joint venture restructuring, so this same part number now appears under two names depending on where you're shopping — "Sennheiser SC 60 USB ML" and "EPOS Impact SC 60 USB ML" are the identical headset, same model 1000551. If a comparison site shows you both, you're not missing a different product; you're looking at the same one under its current and legacy branding.
Built for a full shift, tuned to protect hearing
Per B&H Photo Video's listing, the Sennheiser SC 60 weighs 2.33 ounces (about 66 grams) — light enough to disappear over a long shift — and its ActiveGard technology combines with EU Noise at Work limits to hold average sound exposure to 85 dB across the day, while also cutting off sudden spikes before they reach your ears. The boom mic rotates a full 340 degrees, well past the 180-degree swing most USB headsets offer, so it repositions cleanly whether you wear it left-eared or right-eared.
Zero-configuration deployment
Plug the Sennheiser SC 60 into a USB-A port and it's ready — no driver download, no software install, nothing to configure. That's a real advantage for an IT team rolling this out across a floor: fewer support tickets on day one, and a braided 3-meter cable with strain relief built to survive the tug of a standing desk or dual-monitor setup without fraying at the connector.
