Sound via SD-card is crystal clear, no problems here.
I will try another phone and record the sound quality for you, comparing quality from SD-card and bia bluetooth.

Hi,
After listening the two songs you sent,we find that the sound from Bluetooth is normal.In fact,as Bluetooth is one kind of wireless data transmission, the quality of sound is little worse than the sound from SD card.
Hope your understanding.

Dear Jammy,

sorry but I don't think this is normal, there are Bluetooth receivers available that have a crystal clear sound. As I told you, the record-quality of the samples I sent you is not very good (it has been recorded with my mobile phone).
Please try to test this on your own. Did you do that?

I have the same problem but with bosion headunit. I've searched a lot and found what is allegro about. Every China car headunit manufacturer is using the same poor bluetooth implementantion. Android Has that builtin but every unit Has disabled the onboard bluetooth to use their own with very poor quality. There is no apt-x codec support and without that it's hard to get a good quality sound.

But even on my headphones using standard bluetooth codec (without apt-x) the sound quality is a lot better then on that chineese headunit.
