The Yealink UH38 Dual headset does both at once — a USB cable tethers it to your computer through an inline call control unit, while Bluetooth connects it directly to a mobile phone, both live simultaneously. Answer whichever call comes in without swapping headsets or hunting for a Bluetooth menu.\u003c\/p\u003e\n\n\u003cp\u003eIt's built with a metal-reinforced frame under premium materials, dual noise-canceling microphones, and Yealink's Acoustic Shield Technology — a genuinely solid headset whether the call is coming through your PC or your phone.\u003c\/p\u003e\n\n\u003ch2\u003eBuild the exact UH38 Dual you need\u003c\/h2\u003e\n\u003cp\u003eOne choice: which certification matches your platform.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e[icon:uc] UC Certified.\u003c\/strong\u003e Works with major UC and softphone platforms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e[icon:ms-teams] Microsoft Certified.\u003c\/strong\u003e Certified for Microsoft Teams.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eUSB and Bluetooth, running at the same time\u003c\/h2\u003e\n\u003cp\u003eThe Yealink UH38 Dual headset's inline call control unit has a USB-C port — the included cable adapts it to USB-A, and a USB-C to USB-C cable (not included) works too if your setup needs it. Plug that in for your computer or a compatible Yealink IP phone, and the headset is simultaneously available over Bluetooth for a mobile phone or tablet, reaching up to 33 ft (10m). Need to step away? Unplug the USB cable and the Bluetooth connection stays live on its own.\u003c\/p\u003e\n\n[card title=\"Not either\/or — both, at once\"]The Yealink UH38 Dual headset stays connected to your computer over USB and your phone over Bluetooth simultaneously — not a switch between the two, but both live at the same time.[\/card]\n\n[compare]\u003cdiv\u003e\n\u003cstrong\u003eUSB only\u003c\/strong\u003e\u003cbr\u003eTethered to a computer or compatible Yealink IP phone.

If your office already runs Yealink desk phones, this headset is built to integrate with them specifically, not just tolerate them.\u003c\/p\u003e\n\n\u003ch2\u003eBattery, audio quality, and hearing protection\u003c\/h2\u003e\n\u003cp\u003eThe built-in battery — which powers the Bluetooth side of the connection — delivers up to 7 hours of talk time or 14 hours of music playback, with a full charge from empty taking about an hour over the connected USB cable. A 35mm speaker delivers a wideband frequency response from 20 Hz to 20 kHz, and dynamic EQ automatically switches between call mode and music mode so voice stays clear while music still sounds full.\u003c\/p\u003e\n\n[stat]Up to 33 ft Bluetooth range · Up to 7 hrs talk time (14 hrs music) · 35mm wideband speaker[\/stat]\n\n\u003ch3\u003eComfort, protection, and everyday controls\u003c\/h3\u003e\n\u003cp\u003eActiveProtection technology guards against sudden acoustic spikes on the line, protecting your hearing without you having to think about it. Perforated protein leather ear cushions over memory foam keep the headset comfortable through a full day, and a 320-degree bendable boom arm adjusts to either side with muting handled by lifting the mic up. The inline call control unit includes a dedicated voice-assistant button and a clip you can attach to a pocket or shirt for easy access. Dual busylights, visible from any angle, glow to signal you're on a call — automatically or manually triggered.\u003c\/p\u003e\n\n\u003cp\u003eThis is a headset for someone whose calls genuinely come from two different places — a desk phone or PC softphone, and a mobile line — and who doesn't want to own two headsets or juggle Bluetooth pairing menus to cover both. The dual connection is the actual reason to choose this over a standard USB headset, not a bonus feature tacked onto the spec sheet.\u003c\/p\u003e\n\n\u003cdiv data-tab=\"whats-in-the-box\"\u003e\n\u003cul\u003e\n\u003cli\u003eYealink UH38 Dual headset\u003c\/li\u003e\n\u003cli\u003eInline call control unit\u003c\/li\u003e\n\u003cli\u003eUSB-C to USB-A cable\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\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWearing style\u003c\/td\u003e\n\u003ctd\u003eOver-the-head, stereo (dual ear)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectivity\u003c\/td\u003e\n\u003ctd\u003eUSB (via inline control unit) and Bluetooth 5.1, simultaneous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBluetooth range\u003c\/td\u003e\n\u003ctd\u003eUp to 33 ft \/ 10m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTalk time\u003c\/td\u003e\n\u003ctd\u003eUp to 7 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMusic time\u003c\/td\u003e\n\u003ctd\u003eUp to 14 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCharge time\u003c\/td\u003e\n\u003ctd\u003e~1 hour, via connected USB cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeaker\u003c\/td\u003e\n\u003ctd\u003e35mm, 20 Hz–20 kHz frequency response, 115±3 dB SPL sensitivity, 32Ω impedance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicrophone\u003c\/td\u003e\n\u003ctd\u003eDual noise-canceling mics with Acoustic Shield Technology, 320° bendable boom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHearing protection\u003c\/td\u003e\n\u003ctd\u003eActiveProtection technology\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBuild\u003c\/td\u003e\n\u003ctd\u003eMetal-reinforced frame, protein leather ear cushions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable lengths\u003c\/td\u003e\n\u003ctd\u003e0.8m (headset to control unit), 1.2m (control unit to USB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eYealink IP phone compatibility\u003c\/td\u003e\n\u003ctd\u003eT41S, T42S, T46S, T48S (firmware v82+), T42U, T43U, T46U, T48U, T53, T53W, T54W, T57W, T58A, VP59\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertification\u003c\/td\u003e\n\u003ctd\u003eUC certified, or Microsoft Teams certified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eWindows 8\/8.1\/10, Mac OS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2 years\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 No dedicated software required for core operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHardware:\u003c\/strong\u003e Connects via USB-C (adapted to USB-A with the included cable) through the inline call control unit for a computer or compatible Yealink IP phone.
