Yealink WH64 Hybrid Mono Teams-DECT & Bluetooth Hybrid Wireless Technology

Frequently Asked Questions

First, check that the WDD60 dongle is seated directly in a USB-A port on the computer, not through a hub or docking station, as some docks can disrupt DECT pairing. Confirm the headset is in DECT mode and that the dongle’s LED is solid, not blinking. If it is blinking, re-pair by briefly plugging the headset into the dongle with the USB cable, then unplugging it once paired.
Make sure the microphone boom arm is rotated fully down to the unmute position, as lifting it mutes the microphone. In your softphone or meeting app, verify the Yealink WH64 is selected as the input device, not the laptop’s built-in microphone. If the issue persists, check whether Acoustic Shield 2.0 is enabled in the Yealink USB Connect software, as toggling it on or off can sometimes resolve one-way audio glitches.
Use the included USB-A to USB-C cable connected to a standard USB port or a 5V/1.2A charger; avoid fast-charging adapters that may not be recognized. Inspect the USB-C port on the headset for lint or debris and gently clean it if needed. If the light still does not appear after a few minutes, try a different cable to rule out a cable fault before assuming a battery issue.
The headset can maintain a Bluetooth connection to your mobile and a DECT connection to the dongle simultaneously, but it handles one active call path at a time. To move to your computer, simply end the mobile call and press the call control button on the headset to answer or resume the softphone call. If you need to transfer an in-progress call between devices, that function must be initiated from the call platform or phone app, not the headset itself.
First, confirm the Yealink USB Connect desktop application is installed and running, as it manages the busy light synchronization with Teams. In the software, check that the busy light feature is enabled. The light also depends on your Teams status updating correctly, so verify your presence status changes to “In a call” when you are on an active call.
DECT range is up to 150 metres in open air, but walls, metal shelving, and large electronic equipment will reduce that substantially. Check that the WDD60 dongle is positioned away from large metal objects and not tucked behind a PC tower. If you are using Bluetooth to your mobile, keep the phone on the same side of your body as the headset’s Bluetooth antenna to minimize body-block interference.
No, the WH64 connects via the USB dongle to a computer or via Bluetooth to a mobile device. It does not include an RJ9 connector or a base station that plugs into a traditional desk phone. If you need to pair a wireless headset with a desk phone and a PC, you would need a different Yealink model that supports a physical phone interface.
Power the headset on, then press and hold the call control button for about five seconds until the LED flashes red and blue alternately. Make sure the headset is not still connected to another nearby device that is grabbing the Bluetooth link. If it still will not enter pairing mode, power the headset off completely, wait a few seconds, and try again.

About This Product

The Yealink WH64 Hybrid Mono is built for professionals who split their day between a desk phone or computer and a mobile device. It makes the most sense in open-plan offices, home workspaces, or hot-desking environments across the GTA where a single headset needs to handle softphone calls on a PC and mobile calls without re-pairing. The mono design keeps one ear free for ambient awareness, which is practical for collaborative floors or when you need to hear colleagues in person.

This headset pairs well with Microsoft Teams deployments, thanks to its dedicated certification and the USB dongle that provides a stable DECT link to the computer. The DECT connection gives you the freedom to walk well away from your desk during a call, while Bluetooth handles the mobile side. It is a natural fit for workers who already rely on Yealink desk phones or meeting bars and want consistent audio behaviour across devices.

The trade-off to understand is battery life under real-world conditions. The headline talk time varies considerably between DECT and Bluetooth modes, so a heavy day of DECT calls will drain the headset faster than a day spent primarily on mobile. Acoustic Shield Technology 2.0 does an effective job suppressing steady background hum, but like any noise-filtering microphone system, it cannot completely eliminate unpredictable loud sounds in a chaotic environment.

This headset is overkill for someone who only ever takes calls at a single wired desk phone and never uses a mobile for work. It is underpowered if you need active noise cancellation for your own ears in very loud spaces, as the focus here is on microphone noise reduction for the far end, not immersive silence for the wearer.
