Inspiron G3 15-3590, Qualcomm aptX support?

Hi all,

I got a Dell Inspiron G3 15-3590 laptop with a Qualcomm QCA9377 Bluetooth chip. I paired it with a Sennheiser HD 4.50R bluetooth headphone, which both support aptX codecs.

On Qualcomm site it states that https://www.aptx.com/products/sennheiser-hd-450-btnc-wireless the BTNC version is supported which is identical to the 450R version the only thing not the same is the name of it, but after pairing it the bluetooth uses the A2DP profile not the aptX one.

How can I achieve aptX codec with my headphone?
