14 Steps to Get Your Razer Blackshark V2 Mic Working Again
By systematically looking at hardware factors and software settings, you can understand what's causing the Microphone issue. Follow along below as I go through each methodical troubleshooting step:
1. Confirm Your Headset is Connected Properly
The Razer Blackshark V2 relies on intact cables and a USB port to transmit microphone audio signals from the headset to your PC. Loose plugs into the USB sound card can cause a disconnection.

Ensure that the:
- The headset is fully seated in the USB port.
- Wiggle the connection to confirm that it is fully plugged in.
2. Swap Out Faulty Cables
Over time, bending and fraying can damage the headset cables. Worn-out cables with broken inner wires interrupt the mic audio signal transmitted from the Blackshark V2 to the PC.
Listed below are the helpful solutions:
- Try replacing the auxiliary cable with a new compatible aux cable.
- For USB headsets, swap out the USB cable with a fresh, undamaged one.
- Test the mic function after replacing the cable.
3. Try a Different USB Port and Clean the Headset Jack
Along with cables, the ports you plug the Blackshark V2 into could also be the culprit. This means that even though the wires are completely fine the USB port or headphone jack of the laptop can cause the issue.

Here's what you should do when dealing with faulty ports:
- For USB connections: If using a USB connection, try plugging into a different USB port on your computer. Ports can sometimes malfunction, so switching to a separate one may help.
- For headphone jack: For the 3.5mm audio jack, the actual headphone port itself could be dirty or damaged. Inspect the headset port for any debris, dust, or damage. Clean out the port carefully using compressed air.
4. Test the Blackshark V2 Headset on Another Device
Many users have complained that Shark V2 was not working on their computer, but it was fine on another similar device. This issue usually arises due to compatibility problems, outdated drivers, or issues with the sound settings.
Let's discover what you should do:
- Try plugging your Razer v2 headset into another device to address these issues. Look for a laptop that has similar ports.
- If the mic works fine when connected to other devices, it points to a problem with settings or compatibility, specifically on your primary PC.

However, if it fails on different devices, it indicates a headset defect or problem.
5. Reboot Your Laptop
An easy first software troubleshooting step is to restart your Windows operating system. Complete shutdowns and fresh restarts can reset software configurations and audio driver issues, preventing the microphone properly function.
Here's how you can easily restart your system:
- Click the Start button and hit the power icon;
- Restart your PC and check if the Razer headset mic now works. Often, a fresh reboot will reinitialize components correctly.
6. Adjust the Volume and Unmute the Microphone
The physical mic mute button on the left earcup of the Razer Blackshark V2 disables microphone audio pickup. Accidental bumps or toggles of this onboard mute switch could have turned it on without you realizing it.

A red LED light on the mic button indicates mute is enabled. Here's how you can disable it:
- Press the mic mute button again, which will disable the mute setting. The red light will turn off when the mute is disengaged.
- Adjust the sound levels in the Control panel > Sound and Hardware > Sound icon > Playback & Recording tab. Ensure volume is at 50-100%, not zero or muted.

Here's how you can select the default mic:
- Go to Windows Settings > System > Sound;

- Under the Input tab, check that your Razer headset is selected as the default microphone;
