Bluetooth headphones, digital or analog?

Question

Bluetooth

I found a difference in sound quality if you listen to the same track in the same bluetooth headphones through the phone and from the computer. Headphones denon ah-w150. They are very bassy. Is the analog transmitted when listening to music via bluetooth?

Answer 1

Of course, a digital stream is transmitted via Bluetooth.
The difference may be in the profile of the work - A2DP or some kind of Headset, or even worse - Handsfree.
Inside A2DP, different codecs can also be involved.
But in any case - the signal is digital.
First you need to establish that in both cases the connection goes via A2DP.

Answer 2

Different devices use different bitrates on BT headphones by default, I struggled with this for a long time. Depends on the configs in the system, the chip in the headphones, random. I have cheap headphones from China that work fine with all devices, there are expensive philips from the store, which for some reason turn on a low bitrate with android and sound miserable. I decided for myself that if high-quality sound is required, Bluetooth is not good. Lottery
