Cowin E7/s not working on Windows 10

Hi everyone, 

Im sort of at the end of my rope here, been trying to get this thing to work forever. The Cowin E7's are bluetooth headphones which are pretty nice overall. My only problem is that I cannot for the life of me get them to work. They are able to pair to my PC's bluetooth, and connect just fine as shown below.

The microphone will work just fine. When using discord, it will detect audio being transmitted from my end. My issue however, is that I can't hear a thing. No audio comes through on my end. Youtube videos, Spotify, games, etc. will not transmit any sort of sound. When checking the sound panel settings however, it shows that the green bar for sound is fluctuating, like it is detecting audio.

I have managed to get it to work once, but I am not sure what I did to make it happen. Even then, it would only play audio for about 10 seconds, and then cut out completely and indefinitely until I restarted the PC. Sometimes, the headphones will work just fine, but then the microphone won't be detected at all, preventing me from communicating. Seems to be no middle ground.

I have attempted several fixes, such as deleting the Bluetooth stuff from the Device Manager, changing the Bluetooth support service to automatic, and a whole heap of other things such as changing the windows version in the Registry Editor back to 6.2 instead of 6.3

Does anyone else have these headphones? And if so, have you managed to get them to work? Really frustrated right now, and any help at all would be greatly appreciated.

Thanks,

Jared

This page of MSI lists down BIOS and varioud driver updates. You should update them - https://www.msi.com/Motherboard/support/X470-GA...

Note - Create a system restore point first so that if something wrong happens you can revert.
Type restore point in Cortana Search > Create a Restore point > Check whether against your drive, Protection is ON or not. If not ON, click Configure button below to Make it ON > Now press Create to create a restore point

@P4AK A PUNCH: I have the same problem with my Cowin E7 headphone. It was working fine until the 1903 update to Windows 10. I reverted back to the 1809 release to make it work but Microsoft is ending support for that release. Sent in a problem report to Microsoft to no avail. Hope this is fixed soon!

What I think is going on is that the device is acting as two devices.  A hands free headset and a headphones set.  When you disable the hands free headset profile, it allows the headphones profile to work.  At least, that is what I have experienced with mine.

I have a separate BT dongle, which is working fine and everything pairs and shows up.  I can get some audio tests to work for the headset in hands free mode, however nothing is using it when I set the hands free profile for the audio output.  

I think forgetting and repairing the device should allow us to get reset to where removing the hands free profile allows full stereo sound again.

You may want to reach out to their CS to see if they know of any tricks, since this issue is usually due to design flaws/cost cutting.

I just figured a temp fix until Cowin responds:

1. When connected, go to the bluetooth control panel page

2. Right click on the headphones/device and choose to delete.  Say yes to permanently remove it.

3. Power cycle the headphones to force broadcasting (turn it off and back on).

4. Pair the headset.  Open the sound control panel (not the enhanced windows one, the old control panel -> sound)

5. Make sure the hands free device is present and works.  Check the sound tray by the clock in the taskbar.

6. In the bluetooth control panel, double click the headset.  Right click on the hands free profile and choose disable.

7. In the sound control panel again, set the normal headset as the active device, test, and make sure, like in step 5, that the normal headset is the active device.

It should work and allow music.  You won't have a mic.  If you enable the hands free profile for the mic, it will corrupt the setup and you have to go through the steps above to rebuild it to a working state.  And it may be something to do every time you turn them on and pair them to the machine.  Haven't tested that yet.

I have the same problem. I can re-pair the headset and have both the headphones and the hands-free devices showing in the sound control panel but have yet been able to get the mic work for anything. So far I have only gotten the headphones bit to work and I've tried resolving this for hours now

Thank you for your suggestions, Seikojin. 

I have always had my hands-free headset device disabled since I just use the headphones.

The audio on the headphones just cuts off after a while even though the control panel shows the device as being connected. Sometimes, the audio resumes after a few minutes automatically if I do not do anything. Most of the time, I intervene manually to regain audio by disconnecting the headphone from the control panel and re-connecting. 

Hopefully, Cowin fixes the problem soon.

I wrote Cowin and linked this article and they so far have offered to replace the headset.  I think the issue is not the headset in a fault sense, but in a design sense.

I have some friends and at work have had issues with BT headsets losing audio.  Sometimes this is a fault with a wifi and BT radio on the same chip/circuit. 

Other times there could be power saving features dropping BT when it is 'idle' long enough, hits a power threshold, battery life on the machine, etc.
