Thank you - I'll have a go.Maybe your PC is using SBC (Blue Light), the app will tell you what codec is being used, if that's all it has then your out of luck as far as bluetooth, unless you try using an EQ.
I use "VoiceMeeter Banana" when I want to EQ, it has a very nice Parametric EQ, very easy to setup.
If you want to give it a go
1 - Select VoiceMeeter Input in Windows playback devices. (Set 2 channels)
(Alternative to the above (1), select VoiceMeeter Input in Foobar as output device)
2 - Set VoiceMeeter Banana to use A1 channel then output to BTR3.
Check the screenshot it should help, I removed all the faders on the channels not being used just to make it clearer. I was using wired for the screenshot but Bluetooth shouldn't be any different.

Use the EQ (right mouse click on EQ) on the output ( Master Section) not the input.

What: Amazon dropped the price from £61.99 to £54.99
I use bluetooth for certain situations but for audio I've always stuck with wired to squeeze every last bit of SQ I can get before my aging ears let me down. I'm new to bluetooth streaming so I'm just trying to get my head around what is possible and if so, how to achieve it.
