The Sennheiser SC 665 breaks that rule: its USB cable detaches, and underneath it is a fully functional analog stereo headset that runs over a 3.5mm jack into a phone or tablet, no computer in the chain at all.\u003c\/p\u003e\n\n\u003cp\u003eIt's the mobile member of Sennheiser's premium \"Century\" line — the double-sided, stereo sibling of the SC 630 I've written about before, built for people who genuinely split their day between a desk and a phone rather than sitting at one workstation. Both ears covered, an ultra noise-canceling microphone, leatherette CircleFlex ear cups that fold for travel, and Microsoft Teams and Skype for Business certification.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's different about the Sennheiser SC 665 vs the SC 630?\u003c\/h2\u003e\n\n\u003cp\u003eThe Sennheiser SC 665 adds two things the SC 630 doesn't have: stereo sound instead of mono, and a detachable USB cable paired with a 3.5mm jack for mobile use. The SC 630 is a fixed, USB-only, single-ear headset built for the desk; the SC 665 is built to leave it.\u003c\/p\u003e\n\n[compare]\n\u003cdiv\u003e\n\u003cstrong\u003eSennheiser SC 665\u003c\/strong\u003e\u003cbr\u003eStereo, both ears covered.

Take it off, and the 3.5mm jack alone drives the headset from a phone or tablet — useful for someone who's on a Teams call at their desk in the morning and taking calls from a mobile device the rest of the day, without owning two headsets to do it.[\/card]\n\n\u003ch2\u003eDoes the Sennheiser SC 665 have active noise cancellation?\u003c\/h2\u003e\n\n\u003cp\u003eThe noise cancellation on the Sennheiser SC 665 is microphone-side — it strips background noise out of your outgoing voice before it reaches the call. The stereo ear cups give you passive isolation from covering both ears, but there's no active electronic system canceling incoming sound the way ANC headphones do.\u003c\/p\u003e\n\n[callout type=\"honest\"]Set expectations the same way you would for any headset in this Century line: \"ultra noise-canceling\" describes the microphone, not the ear cups. If a quiet room on your end is the goal, the both-ears passive fit helps, but it isn't ANC. Weight is also worth a real number rather than an adjective — one source lists 3.4 oz, another 3 oz, close enough not to matter for comfort, but worth knowing the figure isn't perfectly nailed down across every listing.[\/callout]\n\n\u003ch3\u003eBuilt for a full shift, wherever it happens\u003c\/h3\u003e\n\n[stat]114-inch cable, 3.4 ozThe Sennheiser SC 665 runs a 114-inch cable when connected over USB, long enough to reach across a standing desk or a dual-monitor setup without strain, and the CircleFlex dual-hinge ear cups fold flat for a bag when you're headed out. ActiveGard technology protects against sudden loud spikes on the line, and the leatherette ear cushions are sized for hours of wear rather than a quick call.\n\n\u003cp\u003eThe Sennheiser SC 665 is the headset for someone who genuinely needs both — a certified Teams headset at the desk in the morning, a standalone stereo headset for a phone or tablet the rest of the day, in one part number instead of two. Detach the cable when you leave the desk, and the same headset follows you, backed by HeadsetPlus's lifetime support.\u003c\/p\u003e\n\n\u003cdiv data-tab=\"whats-in-the-box\"\u003e\n\u003cul\u003e\n  \u003cli\u003eSennheiser SC 665 stereo headset with inline call control unit\u003c\/li\u003e\n  \u003cli\u003eDetachable USB-A cable\u003c\/li\u003e\n  \u003cli\u003eLeatherette ear cushions (fitted, both ears)\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\u003eBinaural (stereo, both-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 665, part of the \"Century Mobile\" line\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eMicrophone\u003c\/th\u003e\n\u003ctd\u003eUltra noise-canceling boom mic\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eNoise handling\u003c\/th\u003e\n\u003ctd\u003eMicrophone-side noise cancellation only; passive isolation from both-ear cushions (not active noise cancellation)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eConnector\u003c\/th\u003e\n\u003ctd\u003eDetachable USB-A cable, plus a built-in 3.5mm jack for standalone mobile use\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eControls\u003c\/th\u003e\n\u003ctd\u003eInline answer\/end, mute, volume\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; UC optimized for Cisco, Avaya, IBM, and other major platforms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eAudio\u003c\/th\u003e\n\u003ctd\u003eHD wideband audio, frequency range approximately 50–18,000 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eEar cups\u003c\/th\u003e\n\u003ctd\u003eCircleFlex dual-hinge, foldable; large leatherette cushions\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\u003eCable length\u003c\/th\u003e\n\u003ctd\u003e114 in (USB connection)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e3.4 oz (approx. 96 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eRelated models\u003c\/th\u003e\n\u003ctd\u003eSennheiser SC 630 (mono, desk-only); Sennheiser SC 665 USB-C (same headset, USB-C connector, different part number)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003e1000645\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e3-year manufacturer warranty, 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 665 is certified for Microsoft Teams and Skype for Business, and works with other major UC platforms including Cisco, Avaya, and IBM.
