Windows 10: Cowin E7 headphone - Windows 10 20H2

I have being experiencing some issues with my Cowin E7 headphone lastly. It was working fine until the 20H2 update to Windows 10. Do you know if it’s related and how to make it work again?

:)

 

Bluetooth devices - Cordless Headphone sound quality has deteriorated.

Bluetooth is on, yet I have questions regarding the Bluetooth devices.

Could you possibly connect remotely with me?

1) One connected device reads as now discoverable as "Edmundo-PC" (I don't

understand what this means.)

2) I had an older COWIN E7 set of headphones and they broke, yet E7 still

shows as a connected device.

3) The replacement set of COWIN E7 new headphones should be listed as "2 E7 Stereo",

but it is not listed on Bluetooth connected devices, yet it is when I click on Volume/Playback.

4) I also have Dolby Atmos (spatial sound) connected. Somehow volume has

become worse - quality wise.

Should you need more information or have questions, please do so. I would

appreciate help on getting this sorted.
Thanks.

Cowin E7 bluetooth headphones connected but not recognized as audio device

I have Cowin E7 wireless bluetooth headphones that have been working fine for about 10 months. They recently stopped working on my Windows 10 laptop (Dell XPS 13). They still connect and work fine using my phone, so the problem is probably with my
laptop. Also, wired headphones still work with my laptop. The laptop does find and connect to the headphones from the "Add Bluetooth or other device", and it stays connected for a little while, but then I only see it as paired in the other devices section.
The weird thing is that it does not appear as an output device for audio. Using the device manager, I've uninstalled my Dell Wireless 1820A Bluetooth 4.1 LE driver and restarted so it would reinstall it, and I did the same thing with the Realtek Audio device
as well.

(This could be unrelated, but I see 2 devices under the Bluetooth section of device manager that I'm not sure what they are, Microsoft Bluetooth Enumerator and Microsoft Bluetooth LE Enumerator. I'm assuming those are supposed be there, but I'm not
sure.)

I contacted Microsoft supporst yesterday, and they told me to do a network reset from Settings -> Network and Internet -> Network reset. This did not seem to solve it. They also emailed me a link to the Windows Media Creation Tool which would upgrade
or update system files, but running that program led to a screen that says "This tool can't update your PC. The language or edition of Windows currently installed on your PC isn't supported by this tool.

If anyone has had a similar issue and has solved it, or if you think you know what to do, any help would be greatly appreciated.
