Jabra Evolve2 40 manufacturer image showing the corded headset and raised microphone boom. On this model, raising the boom normally mutes the microphone; its setting can be changed in Jabra Direct. Lower the boom and check the selected USB input before testing the app.[2]
If a Jabra headset is connected but people cannot hear you, check the actual microphone selected in the operating system and calling app, then check the headset’s physical mute. A speaker that plays music and a USB device that appears in a list do not establish a working microphone. Test input and output separately before changing firmware or resetting the device.[1][3][7]
This guide starts with the hardware path on a Windows or Mac computer. The wired Evolve2 40 is the specific boom-control example; other Jabra models can use different buttons, adapters or settings. A wireless connection that will not establish needs a pairing check before app audio tests.
Find the failed path before changing settings
| What you observe | Next check | What the result tells you |
|---|---|---|
| No Jabra device appears in computer Sound settings | Check the correct USB connection; compare a known working port outside an update | The computer must detect the intended endpoint before an app can use it. |
| Headset speaker works, but the microphone is silent | Check physical mute, selected input and microphone permission | Playback and recording are separate paths. |
| A local recording is clear, but one app is silent | Check that app’s selected mic, permission and in-call mute | A local pass narrows the next test to the affected app; it does not prove the call works. |
| Laptop or monitor audio plays instead of the headset | Choose the intended output explicitly in the OS and app | A dock or monitor can be the selected speaker even while the headset is connected. |
| Audio works, but answer/end buttons do not | Record the exact model, adapter, app and connection type | Call-control integration needs its own check; do not classify every button issue as a failed microphone. |
Write down the names shown in both device lists. If your path uses a Jabra Link adapter, the app may need the Link name rather than the headset’s Bluetooth name. Changing every menu to “Default” makes a later dock or monitor change harder to diagnose.[7]
Check the cable and the model’s physical mute
For a corded Evolve2 headset, connect its USB-A or USB-C variant to the matching computer port. If it is missing, compare a known working port or an approved adapter and note whether a dock is involved. Do this outside an active firmware update. Do not try Bluetooth pairing on a corded Evolve2 40.[1]
On the Evolve2 40, the microphone boom normally mutes when raised and unmutes when lowered; Jabra Direct can change that behavior. Lower it toward your mouth and check the actual setting if the result differs. The manufacturer says the flexible boom is intended to bend inward toward the mouth; do not force it outward. These are model-specific instructions, not a rule for every Jabra headset.[2]
Check the meeting’s mute control as well. A physical mute and an app mute are two places to inspect, even if a supported integration synchronizes them. Start at a comfortable listening volume rather than maximizing every slider.
Compare the computer’s recording path with the app
On Windows 11, open Settings > System > Sound, select the intended input and use the available microphone test. If Windows cannot capture your voice, check Settings > Privacy & security > Microphone. Confirm microphone access and the relevant app access; desktop apps use the desktop-app access setting rather than an individual Store-app switch. Managed settings may require your administrator.[3]
On a current Mac, open System Settings > Sound > Input and select the intended device. Check whether its input level responds while you speak. Under Privacy & Security > Microphone, allow the calling app when appropriate and follow any restart prompt. The OS meter is a local input observation, not evidence that a remote person received speech.[4][5]
Use a short, non-sensitive phrase for a recording or app playback test. Compare the same headset and connection in the affected app. If the local test is clear and the app test fails, retain both results: they tell support more than “the headset is broken.”[3]
Select the actual Jabra path in Teams or Zoom
In the Teams desktop app, open Settings and more > Settings > Devices, then select the intended Speaker and Microphone under Audio settings. Use Make a test call where available and listen to the recorded message. Microsoft documents the test-call feature for the Windows and Mac desktop apps; do not assume the web app has the same test.[6]
In Zoom’s Audio settings, select the Jabra device under both Speaker and Microphone. If the headset is connected through a Jabra Link adapter, Jabra’s setup instructions say to select the Link adapter. Then run the speaker and microphone tests. The Zoom microphone and speaker guide covers Zoom permissions, playback and echo checks in more detail.[7]
Finish with a colleague on a separate device: each person says a harmless phrase and the other repeats it. If a room has several audio-connected devices, isolate which path is active rather than drawing a conclusion from a headset LED alone.
Keep a short comparison record
The following is a proposed troubleshooting record, not a reported customer result. Fill in what you actually observed; an unrun check stays “not tested.”
| Test | Example observation to record | Next decision |
|---|---|---|
| Computer input test | Selected endpoint, mute position, whether speech was recorded clearly | If silent, stay with connection, permission and physical controls. |
| Affected app playback | App version, speaker/mic names and whether the phrase played back | If only this test fails, examine that app’s selection and access. |
| Two-way call | Whether each person heard and repeated the other’s phrase | A local pass alone is insufficient for a call-ready decision. |
| Return from dock or reconnect | Whether the same input/output remained selected | Repeat the selection check if the endpoint changed. |
For escalation, include the headset model and MS/UC variant, wired or Link connection, adapter model, computer/OS, app, exact symptom and the comparison results. Include firmware versions if already available; do not start an update solely to complete a ticket.
Choose the next useful step
If the adapter is present but its headset will not connect, continue with Evolve2 65 and Link 380 pairing. If the exact-model release notes indicate a relevant fix or an update is required by your support plan, use the Jabra Direct update and recovery checklist.

Frequently asked questions
Why does my Jabra headset play sound while its microphone is silent?
Should Teams or Zoom show my headset name or Jabra Link?
Does raising the boom mute every Jabra headset?
No. On the Evolve2 40 example, raising the boom normally mutes and lowering it unmutes; Jabra Direct can change that setting. Check the support instructions for your exact model.
[2]Why is Jabra Direct detecting the headset while a meeting app cannot hear me?
How can I check a Jabra microphone on Windows 11?
Choose the intended input in Settings > System > Sound and run its microphone test. If it is silent, inspect microphone privacy access and the headset’s physical mute before testing the calling app.
[3]Where do I select the Jabra input and allow access on a Mac?
Why does audio move to a monitor after I dock my laptop?
Can I use the same Bluetooth instructions for a corded Evolve2 40?
No. The corded Evolve2 40 connects through its USB-A or USB-C variant. Bluetooth and Jabra Link re-pairing apply to supported wireless models, not that wired headset.
[1]Is the Teams test call available in the browser?
Microsoft documents this test-call feature for the Windows and Mac desktop apps. If it is unavailable, use the app’s available checks and a planned two-way test with a colleague.
[6]What should I send support before replacing the headset?
