Yealink BH74 Teams USB-C/A – 1208678

Frequently Asked Questions

First, check that the BH74 is set as both the speaker and microphone device inside the Teams app audio settings — sometimes it defaults to the laptop’s built-in speakers. Also confirm the BT51C dongle is firmly seated in the USB port and its LED is solid, not flashing. Cycling the call or rejoining after selecting the correct device often resolves this without deeper troubleshooting.
Ensure the microphone boom is rotated down so it sits roughly two finger-widths from the corner of your mouth and that the fabric side is facing you. The boom-arm mute feature can also partially engage if the arm isn’t fully lowered; push it down until you feel a distinct stop. If audio remains faint, try a test recording in a voice memo app to rule out a platform-specific issue.
Busy light sync typically requires the Yealink USB Connect software to be installed and running on your computer. Verify the software recognizes the headset and that the busy light setting is enabled. On some UC platforms, the light only activates during a connected Teams call, not during dialing or holding, so test with a live call to confirm behavior.
Echo like this often comes from the speaker volume being set too high, causing the microphone to pick up audio leaking from the earcups. Lower the listening volume gradually and ask the caller if the echo fades. If it persists at moderate levels, temporarily disable ANC and ambient-sound modes to see if the processing algorithm is contributing to the feedback loop.
Hold the power button for a full three to four seconds — a quick press won’t start it. If there’s still no LED activity, try a different USB-C cable and a standard 5W wall charger, not a high-wattage laptop charger, as the headset may refuse to negotiate power with very high-output adapters. After it powers on, check for a firmware update through Yealink USB Connect.
This usually happens when the headset has an active Bluetooth connection to two devices and one grabs the audio path. On your phone, go into Bluetooth settings and confirm both call audio and media audio are enabled for the BH74. If the dongle is still plugged into your computer and active, disconnect the computer Bluetooth briefly to isolate which device is holding the call channel.
The BH74 connects over Bluetooth, USB dongle, or USB cable. Unless your desk phone has a USB port that supports audio accessories or built-in Bluetooth, there’s no direct wired-3.5mm fallback. Some Yealink IP phones can pair with it via Bluetooth, but you’ll need to check your specific phone model’s accessory compatibility. If the desk phone lacks both, this headset is best treated as a softphone companion.
Active Noise Cancellation draws additional power, which means you’ll go through more charge cycles if you run it continuously. Over months, that can slightly accelerate the natural degradation of the lithium battery compared to using ANC only when you truly need it. The headset’s battery management does protect against overcharge, so charging habits matter more than ANC alone, but using ANC selectively will stretch both daily runtime and overall battery lifespan.
Confirm the BT51C is pushed into a USB-A port via the adapter and not a USB-C hub that may not pass audio devices properly. On macOS, open the Sound preferences and select the BH74 as both input and output — macOS sometimes picks the dongle for output but leaves the internal mic as input. If the dongle still isn’t visible, a quick restart of the Mac with the dongle inserted often triggers the needed driver detection.
A subtle background hiss is a byproduct of the active noise cancellation circuit and is more noticeable in a completely silent room. Try toggling ANC off to see if the hiss disappears; if it does, the level you’re hearing is within normal operational limits for ANC headphones. If the hiss is loud or uneven, perform a full power cycle and, if it continues, reach out to your equipment provider for an assessment.

About This Product

The Yealink BH74 Teams Edition is built for professionals who spend a significant portion of their day on calls and need a headset that can move with them. It’s a strong fit for a hybrid worker splitting time between a noisy open-plan office in downtown Toronto and a quieter home environment. The combination of a dedicated Teams button, a USB dongle for a rock-solid desk connection, and simultaneous dual Bluetooth lets you monitor a personal phone while staying live on a work call.

This headset pairs naturally with Yealink desk phones and IP phones, but its USB dongle connection makes it equally effective as a softphone daily driver on a laptop. The acoustic shield and six-mic array aim to handle the kind of background chatter found in a bustling GTA brokerage or sales floor, though it’s over‑engineered if you’re mostly taking calls in a private, quiet office. The dual-sided busy light is a practical touch for signaling focus time in shared spaces.

Battery life tilts toward marathon use, with talk time rated well beyond a standard workday when ANC is off. With ANC enabled, run time will tighten, so managing that toggle becomes part of the daily routine. The hearing protection features go beyond basic peak limiting, adding daily noise exposure tracking, which is a thoughtful inclusion for contact centre or all-day calling scenarios. Weight and clamp force are in the comfort zone for extended wear, but anyone sensitive to on-ear pressure should still test-fit before committing to a fleet rollout.

For a small business deploying Microsoft Teams across a dozen staff, the BH74 lands in a sweet spot: Teams certification avoids the driver and call-control quirks of uncertified audio devices. The trade-off is that it’s a personal headset, not a shared-device solution, so it won’t suit hot-desking environments without a clean pairing handoff process. If your calling is entirely mobile and you rarely dock at a computer, a simpler true-wireless earbud may serve you better, but for the desk-plus-mobile pattern this device targets, the BH74 covers the bases well.
