How to stream lossless audio over BT in Ubuntu?

Question

Bluetooth

Connecting speakers via analog wire and bluetooth produces a big difference in sound quality. When connected via a 3.5 jack, "Analog Headphones" built-in audio appears in the sound settings. And when on the bluetooth "Headset". Perhaps in the first and second case, the sound is transmitted differently and can this be changed in the settings?
Or is it the transmission quality?

When a device is defined as a "headset", it is an HSP profile that uses a 64 kbps codec specifically for voice only to transmit audio.
When a device is defined as a "speaker", it is an A2DP profile that can use different codecs, different bitrates and sample rates, which allows for better music transfer. https://en.wikipedia.org/wiki/SBC_(codec)

Answer 2

For BT, compression is used anyway. There are many formats, but compression will still be.

Answer 3

I bought Thonet & Vander Vertrag BT speakers, they were defined as a headset. Accordingly, the sound was bad, and it was audible. Where was the mistake then?
