Microphone usage only possible with bad quality

simple listening to Musik on my H800 Logitech headset works ((Windows Sound is set to "Headphones (H800 Logitech Headset Stereo)" ).

The headset doesn't work in Microsoft Teams or Skype.

My OS is Windows 10.

It seems to only work in two modes:

1) In Ms Teams, when I choose speaker option "Headphones (H800 Logitech Headset Stereo)", I hear my partner very well, but the microhone does not work.

2) If I choose "Headset (H800 Logitech Headset Hands-Free AG Audio)", I hear my partner in very bad quality, and also my partner hears me very bad.

I tried many advices from the Internet but nothing worked:

Un- and reinstall all related drivers

System reboot

re-installed Headset in device manager

Downloaded drivers for the headset (was only available for Windows 7)

Deactivated "Hands Free" Bluetooth option in Device&Printer services (but this just deletes the microphone functionality).

What I expect is that I can use the headset with MS Teams, that I can hear my partner well, that I can use the microphone, and that my partner hears me in good quality.

Spent already a whole day on that and am pretty frustrated.

This is by design. It is a limitation of Bluetooth especially for older hardware/OS.

The microphone is only available via HFP/HSP, not A2DP, forcing lower quality audio codec whenever microphone is used.

Yes right. Many thanks. It was pretty hard to find that information in the web, but I found an article explaining it quite well:


@flotschie Newer builds of Windows will support more high-quality codecs in A2DP mode and smart switching between HSP/HFP and A2DP, no more choosing between 2 devices (Hands-Free or not). But it will not improve call quality in HFP.

Maybe get new headphones that support Bluetooth 5.0?


Ok thanks, well I just bought them :D %#*@...

EDIT: No wait they support bluetooth 5.0... ?!


I don't think H800 does, it is a very old device.


You are right seems I did not check properly. Whatever - with the nano dongle everything works well at leas.

See if you can get any better of an input quality with ASIO (

Thank you I will maybe consider that later. For now I am happy that at least it works with the dongle. I can't and don't want to spend more time on that topic :D
