EPOS SC 660 ML USB Stereo Headset – Teams Certified
The EPOS SC 660 folds its speakers flat
A premium headset that takes up as much desk space as a cheap one isn't really solving the problem it was bought to solve. The EPOS SC 660 is built with that in mind — its speaker housings turn a full 90 degrees for compact storage and travel, on a headset that otherwise carries the full Century-tier build: stainless steel hinges, brushed aluminum, and a Vectran-reinforced cable.
It's the stereo member of EPOS's premium IMPACT 600 "Century" line, with an ultra noise-canceling microphone, EPOS Voice HD audio, large leatherette ear cushions, and ActiveGard protection against sudden sound spikes. It's Microsoft Teams and Skype for Business certified, connects over USB-A, weighs about 6 ounces, and carries a 2-year international warranty.
Does the EPOS SC 660 have active noise cancellation?
Not this version. The EPOS SC 660 ML uses an ultra noise-canceling microphone — filtering background sound out of your outgoing voice — rather than active noise cancellation for what you hear. EPOS does sell a separately badged "SC 660 ANC" variant with genuine active noise cancellation and a proximity sensor, but that's a different product line from the SC 660 ML covered here.
The magnetic holder that actually gets used
One-touch, every time
The in-line call control unit on the EPOS SC 660 snaps into a magnetic holder built into the headset itself — no fumbling to find the right button on a loose cable. It's a small mechanical detail that solves a genuinely annoying daily problem: the control unit always ends up in the same predictable spot, ready for a one-touch answer the moment a call comes in.What's the difference between the EPOS SC 660 and the SC 630?
Ear count, and nothing else in the core build. The EPOS SC 660 is stereo, covering both ears; the SC 630 is mono, covering one. Both carry the same Century-tier materials — stainless steel hinges, brushed aluminum, Vectran-reinforced cable, unibody headband — and the same ultra noise-canceling microphone.
Both ears covered, more isolation from a noisy room. Same premium Century materials as the SC 630.
One ear covered, stays aware of the room. Identical build quality and warranty.
If you've compared this against the budget-tier EPOS SC 260, the difference is steeper: the SC 260 uses foam-and-leatherette cushions and a metal-reinforced (not stainless steel and aluminum) headband. The SC 660 is the materials upgrade across the board, not just a name change.
Built to survive a stress test, not just a shift
The unibody headband on the EPOS SC 660 is reinforced at its stress points, the hinges are stainless steel rather than plastic, and the cable itself is wrapped in Vectran — a fiber used in industrial and aerospace applications for its tensile strength, not something you'd expect on a headset cord. Numbered indications on the extension headband let you dial back to your exact adjustment instead of re-eyeballing the fit.
Folds flat, travels flatter
Between the 90-degree turnable speaker housings and foldable ear cups, the EPOS SC 660 collapses into a genuinely compact shape for a headset built from steel and aluminum — worth knowing if this headset is going in a bag as often as it sits on a desk.
The EPOS SC 660 is the headset for someone who wants premium materials on both ears and doesn't want to babysit the cable or the fit — Vectran reinforcement that shrugs off daily wear, a numbered headband that remembers your setting, and a magnetic control-unit holder that puts the answer button in the same place every time. Plug it in over USB, and it's ready the moment Teams recognizes it.
