I have a Plantronics BackBeat Sense SE bluetooth headset. When Connecting it to Windows 10, it installs two profiles in Playback devices list:

  1. PLT_BBTSENSE Hands-Free.

  2. PLT_BBTSENSE Stereo.

The Second one (Stereo) is set to be the "Default Device" and the "Default Communication Device" on the system.

At this point the sound works great and normally. The problem happens when I want to use the mic. When I start any program that uses the mic (recorder, chat, VoIP Calls, gaming, etc.) The sound suddenly stops working And I can only use the mic until I stop the recorder or the call.

The thing that kind of fixes the problem is setting the (Hands-Free) as the default device. I can hear the sound when I do that and it works with the mic but it becomes Very bad quality.

What I became to understand is that bluetooth had different profiles for sound and mic: A2DP and HSP. The first handle the voice(High Quality) but the latter handles the mic and reduces the sound quality.

Is this really the case? Is there anyway to make them work simultaneously? Is there any solution to this problem at all?

Short:

No

Long:

There are so called Profiles in Bluetooth, and only one can be active at a time.

A2DP supports one-way HQ audio.

HSP/HFP support two-way audio, but only in a shitty quality (HFP 1.6 added mSBC, which is a 16kHz mono codec, before, it was even worse).

(I added the same answer to both Is it possible to use a bluetooth headset mic while having High quality sound and Bluetooth handsfree better quality because they are found using google.)
