EPOS IMPACT SC 665 USB — Double-Sided Wired Office Headset

3.5 mm jack plus detachable USB cableUltra noise-cancelling microphoneEPOS ActiveGard hearing protection95 g with Vectran-reinforced cable

The EPOS IMPACT SC 665 is a double-sided wired on-ear headset from the IMPACT 600 series, built for people who sit at a computer all day and want a cable rather than a battery. This article, 1000645, terminates in a 3.5 mm jack on the headset itself and comes with a detachable USB-A cable that carries the in-line call control, so the same headset covers a computer and a phone or tablet. It weighs 95 g, uses a neodymium speaker published at 50 Hz to 18,000 Hz, and pairs an ultra noise-cancelling microphone with EPOS ActiveGard acoustic-shock protection.

Compatibility — check before buying:
This article is USB-A. The USB-C version of the same headset is a different part number, 1000670 — check your ports before ordering. The 3.5 mm cable is the headset’s own termination and the USB cable is the detachable part, not the other way round, and that matters for what you can do: running through the USB cable you get answer, end, volume and mute; on the 3.5 mm cable alone EPOS publishes answer and end only. On the certification side, EPOS still prints Skype for Business on this series and publishes no Microsoft Teams certification for it, so if a Teams certification is a requirement in your organisation this is not the article to buy. There is also no Easy Disconnect or RJ9 connection here, so it does not attach to a traditional desk phone. And note the neighbouring articles: SC 660 USB ML, 1000553, is the USB-only model with no 3.5 mm jack.

Best For

✓ Computer-based call handling where a cable beats a battery
✓ Contact centres that cannot afford a headset going flat mid-shift
✓ Open-plan desks that need an ultra noise-cancelling microphone
✓ Organisations that require acoustic-shock protection on the line
✓ Staff who also take calls on a phone or tablet through the 3.5 mm jack
✓ Long shifts: 95 g with leatherette on-ear cushions

Key Features

 
Neodymium speaker, 50 Hz to 18,000 Hz
EPOS publishes a high-quality neodymium magnet speaker with a 50 Hz to 18,000 Hz response, which is a wider range than most call-only headsets and makes a difference on video calls and on media between them.
 
Ultra noise-cancelling microphone
The microphone is published at 150 Hz to 6,800 Hz wideband with ultra noise cancellation, so the room around you stays out of what the other side hears. Wideband matters on any modern IP or softphone call.
 
ActiveGard and the EU noise limiter
EPOS ActiveGard protects against acoustic shock from a sudden burst on the line, and the headset also carries an EU Noise-at-Work limiter averaging 85 dB across a workday. Maximum SPL over USB is published at 118 dB.
 
Built to be worn, and to survive
Vectran-reinforced cables and a unibody headband, 95 g on the head, leatherette on-ear cushions, and a carry pouch, magnetic holder and pre-mounted cable clip in the box.

Frequently Asked Questions

What exactly is detachable on the SC 665 USB?
The USB-A cable, which is also the one carrying the call-control unit. The headset itself ends in a 3.5 mm jack, so unplug the USB cable and you have a plain 3.5 mm headset for a phone, a tablet or a laptop jack. That also means a damaged USB cable can be replaced without replacing the headset.
Is it certified for Microsoft Teams?
No. EPOS publishes this series as UC optimised and Skype for Business certified, and Skype for Business branding is now retired. If Teams certification is a procurement requirement, look at a current Teams-certified model instead — we will point you at one.
How much control do I get on the cable?
Through the USB cable: answer and end a call, volume up and down, and mute. On the headset’s own 3.5 mm cable EPOS publishes answer and end only, so volume and mute come from the device.
What is in the box apart from the headset?
The carry pouch, a magnetic holder, a cable clip already mounted on the headset, the leatherette ear pads fitted, and the quick and safety guides, plus the detachable USB-A call-control cable. There is no USB-C adapter and no Easy Disconnect cable.
Singular Expert Insight
This is a mature design and that is its strength: a wired headset has no battery to die in the middle of a shift, the 3-year EPOS term is longer than almost anything in this category, and ActiveGard plus the EU limiter cover the compliance side that matters in a contact centre. Where you have to be careful is the family: the SC 665 USB is the one with a 3.5 mm jack and a detachable USB-A cable, while the SC 660 USB ML, 1000553, is USB-only with a fixed cable, and the USB-C version of this headset is a different article, 1000670. The other thing to know before you commit is the certification: EPOS still prints Skype for Business here and publishes nothing for Teams. Our Office & VoIP Headsets category has the Teams-certified USB and Bluetooth models, and Headphones covers the analogue boom-mic options for desk phones. Tell us the softphone and the phone model and we will confirm the article and any cable you need.

Buyer’s Guide

Buy it if

You want a wired stereo office headset with a professional noise-cancelling microphone, acoustic-shock protection and a three-year manufacturer term, and you would rather not manage batteries. You also want the option of taking calls on a phone or tablet through the 3.5 mm jack.

Skip it if

You need Microsoft Teams certification, Bluetooth freedom, or a connection to a traditional desk phone — this article has none of those. Skip it too if your laptop is USB-C only, because the USB cable here is USB-A and the USB-C version is article 1000670.

Also consider

SC 660 USB ML, 1000553, if you only ever use a computer and want a simpler single-cable headset, SC 665 USB-C, 1000670, if your laptop is USB-C only, or a current Teams-certified USB headset if certification is required.
