Hi friends

Is anybody using the Bose Bluetooth box Bose S1 Pro System  ?
And if yes, which bluetooth adapter do you use and are you pleased with that box ?

Best Regards

Hi friends,

I just received a message from Thomann

bluetooth is not working with Yamaha keyboards 

I thought it would be possible with an USB bluetooth !!

Cheers
