Hello everyone!
Tell me please, which bluetooth adapter do I need to use to connect Life Q30 via bluetooth on Windows 7? I’m using a csr8510 a10 with CSR Harmony. Headphones are added to the list of devices, but none of the services, including A2DP, are active, forced launch does not work. Thanks.

You are still in WIN7.
Hope you find someone who can help.
May be you should upgrade to WIN10.
But if the hardware is too old go for a LINUX-System.
Works properly!. 
There may not be any drivers that support Windows 7 for something this new. Microsoft stopped supporting Windows 7 back in January 2020. Most companies won’t build drivers/software that work on unsupported operating systems.
