Razer BlackShark V2 Pro mic not working on applications.

im having the same issue with my razer blackshark v2 hyperspeed! It is really annoying it was working fine yesterday, i try to use them today and the mic just isnt working. ive tried many troubleshooting methods and havent found anything online to help. i hope you find a fix soon. 

yeah bro im having the same issue too they must of broke something in synapse new update or something cause it was working fine last night

I’ve been having the same issue on the  Blackshark V2 Pro (2023) headset. It was working entirely fine yesterday with no issues whatsoever and today after testing my mic on discord it’s not being picked up whatever despite windows still picking it up in the sound settings. I’ve already uninstalled and reinstalled many sound drivers, removed and reconnected the device through Bluetooth, disconnected and reconnected the usb and reinstalled Razer Synapse yet the problem still persists. 

I have the exact same issue with the same headset! Mic worked as recently as two days ago and suddenly it’s not getting picked up by any applications anymore (for example Discord or Streamlabs, not even the sound test in Synapse). Also tried reinstalling drivers, reinstalling Synapse (both 3 and 4), even without Synapse, replugging the USB dongle. No changes. Win10 audio settings show the mic volume bar moving, sidetone is working while either in Synapse or any other app that actively tries to use the mic (tested Windows audio settings, Discord and Streamlabs). Bluetooth mode does work, but sound is abyssmal, so not an option for streaming or recording.

Same issue on Win11 Hyperspeed V2 but Bluetooth does not work either.

Similar headset Blackshark v2 Pro (2023) with a similar issue regarding the mic -- though for some reason joining a Discord channel will show voice activity and I can hear myself on Discord’s mic monitoring but the Synapse Mic monitoring doesn’t visibly respond or allow me to hear myself at all. Along with my THX Spatial audio or EQ profiles not making any difference to the sound of the audio and even seeming to reset back to stereo according to the Synapse App’s UI if I hit the refresh button in the upper left corner. 

All started after an update to the Synapse app or headset itself yesterday then a PC restart.

Same issue here

Same problem here and it's honestly ridiculous i managed to dig up a temporary fix, but lets be real the mic is still way too quiet, and the sound quality is nowhere near acceptable for a headset in this price range. go into your sound settings, find the microphone, and switch the audio enhancement to Voice Clear using the Windows audio enhancement tool. It’s a band aid, not a solution this shouldn’t even be an issue

Exact same issue here after installing the latest update. I tried reinstalling Synapse 4, I tried using Synapse 3 and I tried updating firmware but nothing worked, only steps that worked were either connecting through bluetooth (which makes the audio from both the mic and headset sound awful) or using it without having Synapse installed (which ALSO makes both sound awful).

After talking to support they offered me RMA, which is unfortunately entirely pointless, since it’s not an issue with hardware but rather software. You can clearly tell, since the microphone level in Synapse shows up as undefined. Software has been an issue for quite some time now and I’m honestly pretty fed up at this point, since I’m reliant on the microphone working.

it for sure must be in the software because there's no way it all stops working for us at the same time 

Hi Folks,

I am just adding to this but with a different product! I have a Razer Kraken v4 Headset and my issues are very similar and also started yesterday when I booted up to game, the night before was just fine.

My issues are that Razer Synapse can apply the colour settings, but when I try to apply THX Spatial Audio in the Sound tab, there’s no change to the sound in the headphones, and when I refresh the page is flips back to Stereo without me changing anything, same in the Demo tab where you can play a video and swap between the two. No difference, it’s like Synapse is blocked from making the change somehow.

It’s the same for the Mic Sidetone setting, that stopped working too, and no matter if I turn it off or on it makes no difference, it stays off and I can’t hear myself. Only when I go into Windows sound settings does the Mic turn on and I can hear myself, as soon as I navigate away from the sound options the mic turns off.

Same for applying Bass Boost, or Volume Equalisation, or any other options, non are being pushed to the headset!

I have been through all the recommended steps of setting devices as the default playback/recording device and setting enhancements to off or on or disabled etc, I reinstalled synapse, reset the headset, deleted the profile and started again, nothing made a difference.

I was already on Synapse version 4, there was an update available, and I installed it but that didn’t make a difference. The only other install yesterday was a Windows update: https://support.microsoft.com/en-gb/topic/september-23-2025-kb5065790-os-build-22621-5984-preview-cb0b964a-c953-4605-a203-572dde2d9433

I even tried uninstalling the windows update and that didn’t work either!

I am on Windows 11, and I can gather all the different versions of programs that I am on etc if it would be useful, but to me it sounds like some sort of software update/windows update that has happened which has broken the communication between Synapse and the headset.

Not sure on next steps other than raising the awareness so the Razer devs can get on it!

Thanks,

Tom.

I’ve just seen that someone has picked up on this over on the Reddit Razer Sept 25 Technical Support post: https://www.reddit.com/r/razer/comments/1n59zmj/september_technical_support_sticky/

You’ll need to go down to the Audio post and look at the replies:

Mic stopped working entirely when Synapse is installed as of today. After I uninstalled it worked, but obviously without the Synapse Settings, as I reinstalled it stopped working again. I can sometimes see the mic picking up sound in the Windows Preview, but that's inconsistent and even if it's the case, the mic preview in Synapse and other apps don't get any sound from it.”

Im getting same issue here, Razer Blackshark v2 pro 2023, it kinda helps knowing that i didnt mess it up and they did.

I’ll try that when I get home!

currently working for me as well! 

Thank you very much for this suggestion, just installed it and it WORKS! Hopefully it stays that way and will eventually be fixed for the proper release version as well.

Downloaded the beta and now my mic works perfectly, thanks!

Hi Folks,

I got home and tried the Beta and it didn’t work for me. However! I did spot a comment from one of the Razer devs over on this thread: https://www.reddit.com/r/razer/comments/1npnk9v/comment/ng0sov6/?context=3

Hey! I'm on the Razer Software Team.

This should have been hotfixed last night. Let me know if it's still an issue.”

So I downloaded the standard version 4 again fresh from the website https://www.razer.com/gb-en/synapse-4 and they have indeed hotfixed it!

This worked for me on my Razer Kraken v4 headset, what if you guys tried reinstalling now and see if it works for you?

Cheers,

Tom.

The fix is simply updating to the Synapse 4 beta or reinstalling the latest Synapse 4 build with the hotfix, since the mic issue came from a software update and not the headset itself.

Updating to synapse 4 being the “fix” might seem great up until you realise how buggy synapse 4 is, there’s a reason a lot of people went back to synapse 3 after upgrading to synapse 4 and lets be real here, doesn’t it seem strange that now your headsets don’t work on synapse 3.

I’m not into conspiracies but what better way to force people to go to synapse 4 by breaking their hardware if you’re not on synapse 4.

I have the exact same issue with my Razer BlackShark V2 Pro (2023). Everything works fine normally, but as soon as I launch the game (Ghost Recon Breakpoint), the microphone stops working entirely. It stops working everywhere—not in the game, not on Discord, nor on WhatsApp. Once I close the game, unplug the USB dongle, and plug it back in, the mic starts working again, but launching the game breaks it all over again. I've tried many methods online and nothing helps. Could someone please help me fix this?
