The Yealink UH38 Dual Headset Most headsets make you pick: plugged into your computer, or paired wirelessly to your phone. 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. It'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. Build the exact UH38 Dual you need One choice: which certification matches your platform. [icon:uc] UC Certified. Works with major UC and softphone platforms. [icon:ms-teams] Microsoft Certified. Certified for Microsoft Teams. USB and Bluetooth, running at the same time The 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. [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] [compare] USB onlyTethered to a computer or compatible Yealink IP phone.

Unplug USB and Bluetooth keeps working.[/compare] Built specifically to pair with Yealink desk phones Beyond generic USB compatibility, the Yealink UH38 Dual headset connects directly to specific Yealink IP phone models — the T41S, T42S, T46S, T48S, T42U, T43U, T46U, T48U, T53, T53W, T54W, T57W, T58A, and VP59 (older T4xS models need a firmware update to version 82 or higher). If your office already runs Yealink desk phones, this headset is built to integrate with them specifically, not just tolerate them. Battery, audio quality, and hearing protection The 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. [stat]Up to 33 ft Bluetooth range · Up to 7 hrs talk time (14 hrs music) · 35mm wideband speaker[/stat] Comfort, protection, and everyday controls ActiveProtection 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. This 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.
