The Sennheiser SC 630 ML is built for exactly that tier of work: a single-sided USB headset with what Sennheiser calls an \"ultra\" noise-canceling microphone, a step up from the standard noise cancellation on the entry-level Sennheiser SC 60.\u003c\/p\u003e\n\n\u003cp\u003eIt's a mono headset — one ear covered, the other open — built from stainless steel and brushed aluminum rather than the lighter plastic construction of Sennheiser's budget lines, with foldable CircleFlex ear cups, ActiveGard hearing protection, and Microsoft Teams certification carried under the same \"ML\" naming convention as the SC 60 (a leftover from its original Microsoft Lync certification). It connects over USB only — there's no 3.5mm option, no bottom cord for a desk phone.\u003c\/p\u003e\n\n\u003ch2\u003eIs the Sennheiser SC 630 the same as the SC 60?\u003c\/h2\u003e\n\n\u003cp\u003eNo — the Sennheiser SC 630 is the step-up model, and the difference isn't cosmetic. Where the SC 60 uses a standard noise-canceling microphone and foam ear cushions, the SC 630 carries an ultra noise-canceling mic tuned for genuinely loud rooms, a stainless steel and brushed aluminum build instead of a lighter composite frame, and leatherette ear cushions rather than foam.\u003c\/p\u003e\n\n[compare]\n\u003cdiv\u003e\n\u003cstrong\u003eSennheiser SC 630\u003c\/strong\u003e\u003cbr\u003eUltra noise-canceling mic, steel and aluminum build, leatherette cushions, foldable CircleFlex cups.

It's built for a computer: softphones, video calls, dictation software, anything running through a PC. If your phone's headset jack is the older RJ-style connector rather than USB, this isn't the headset for that setup.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt like \"The Century\"\u003c\/h3\u003e\n\n[card title=\"A nickname that says something about the build\"]Sennheiser's internal name for this headset is \"Century,\" and the construction backs it up — stainless steel and brushed aluminum components instead of plastic, a unibody headband reinforced at the stress points, and a numbered adjustment scale on the headband itself. That last detail matters more than it sounds: on a shared desk or a hot-desking floor, an agent can note their number and dial straight back to it every shift instead of eyeballing the fit from scratch.[\/card]\n\n[stat]5 oz (approx. 142 g)[\/stat]\n\n\u003ch3\u003eCircleFlex keeps the fit precise, folds for travel\u003c\/h3\u003e\n\n\u003cp\u003eThe CircleFlex dual-hinge ear cup pivots to sit flush against your ear regardless of head shape, then folds flat when you're done — genuinely useful if this headset travels between a desk and a laptop bag rather than living in one spot all day.\u003c\/p\u003e\n\n\u003ch3\u003eOne ear covered — know when that's not enough\u003c\/h3\u003e\n\n[callout type=\"honest\"]The Sennheiser SC 630's noise cancellation works on the microphone side — it strips background noise out of your outgoing voice, not out of what you hear. It's a single-sided design, so one ear stays open to the room. If your environment is loud enough that hearing your caller clearly over the background is the actual problem — not just being heard clearly yourself — a binaural (both-ear) headset will serve you better than upgrading the mic alone.[\/callout]\n\n\u003cp\u003eThe Sennheiser SC 630 is the headset for someone whose voice quality genuinely can't afford to slip — dictation, high-volume customer calls, hours of daily meetings where a garbled word costs real time. The ultra noise-canceling mic, the steel-and-aluminum build, and a warranty that reflects Sennheiser's own confidence in it add up to a headset built to outlast the desk it sits on.\u003c\/p\u003e\n\n\u003cdiv data-tab=\"whats-in-the-box\"\u003e\n\u003cul\u003e\n  \u003cli\u003eSennheiser SC 630 ML single-sided USB headset with inline call control unit\u003c\/li\u003e\n  \u003cli\u003eLeatherette ear cushion (fitted)\u003c\/li\u003e\n  \u003cli\u003eCarrying case\u003c\/li\u003e\n  \u003cli\u003eQuick start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cdiv data-tab=\"specifications\"\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eMonaural (single-ear), over-the-head, on-ear\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eAlso sold as\u003c\/th\u003e\n\u003ctd\u003eEPOS Impact SC 630 USB ML, nicknamed \"Century\"\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMicrophone\u003c\/th\u003e\n\u003ctd\u003eUltra noise-canceling boom, rotates for left or right ear wear\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eNoise handling\u003c\/th\u003e\n\u003ctd\u003eMicrophone-side noise cancellation only; no active noise cancellation for the wearer\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eConnector\u003c\/th\u003e\n\u003ctd\u003eUSB-A, direct connect, fixed cable with inline control unit — computer only, no analog or desk phone connection\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eControls\u003c\/th\u003e\n\u003ctd\u003eInline answer\/end, mute, volume; magnetic desk holder for the control unit\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCertification\u003c\/th\u003e\n\u003ctd\u003eMicrosoft Teams and Skype for Business certified (\"ML\" = original Microsoft Lync certification, carried forward)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eBuild\u003c\/th\u003e\n\u003ctd\u003eStainless steel and brushed aluminum, unibody headband with numbered adjustment scale\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eEar cups\u003c\/th\u003e\n\u003ctd\u003eCircleFlex dual-hinge, foldable; leatherette cushion\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eHearing protection\u003c\/th\u003e\n\u003ctd\u003eActiveGard technology — protects against acoustic shock and sudden sound spikes\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e5 oz (approx. 142 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eRelated model\u003c\/th\u003e\n\u003ctd\u003eSennheiser SC 60 (standard noise-canceling mic, lighter build, lower price)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003e1000552 (old 504552)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e3-year manufacturer warranty (confirm against current stock), plus HeadsetPlus lifetime technical support\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003cdiv data-tab=\"compatibility\"\u003e\n\u003cp\u003e\u003cstrong\u003eSoftware.\u003c\/strong\u003e The Sennheiser SC 630 is certified for Microsoft Teams and Skype for Business, and works with other major UC platforms including Cisco, Avaya, and IBM.
