Frequently asked questions about this product

What does the “ML” in EPOS Impact SC 660 USB ML stand for?
It denotes the version optimised for Microsoft Lync, which later became Skype for Business. EPOS specifies that the SC 660 USB ML has been tested and approved by Microsoft’s teams.
What makes this headset built for intensive use?
Its materials: a one-piece headband in stainless steel and brushed aluminium and a Kevlar-reinforced cable. That trio is what gives way first on a call-centre headset — headband, hinge, cord.
Do the ear cups fold flat on the SC 660?
Yes, they swivel through 90° for storage: the headset lies flat on the desk or slips into a drawer without straining the headband.
Can the mic boom be worn on the left or the right?
Yes, the ultra noise-cancelling boom can be worn on either side. It operates over 150 to 6,800 Hz, the useful speech range, so that only your voice is transmitted.
Does the SC 660 protect the ear against acoustic shocks?
Yes, through the ActiveGard system, which caps the sound pressure level at 103 dB. At a workstation with back-to-back calls, it is this limit that protects you from feedback or a shock on the line.
How long is this headset’s cable?
2.9 m, one of the longest in the category: enough to reach a tower under a neighbouring desk or a distant docking station without stretching the cord. The headset weighs 167 g without the cable.
What sound quality can you expect from this professional headset?
Sennheiser wideband HD sound from dynamic neodymium-magnet transducers, in a closed-back design, covering 50 Hz to 18 kHz. Its impedance of 200 ohms is well above the category average.
What is in the box of the EPOS Impact SC 660 USB ML?
The headset, a magnetic clip for the remote control, a quick installation guide and a safety manual. The magnet lets you fix the control unit within easy reach rather than leaving it dangling.
Is this EPOS Impact SC 660 new and under warranty?
Yes, new in its original EPOS packaging. Your invoice serves as the warranty document and covers 2 years on this part number. Calls are managed with the remote control built into the cord.
