Order received and thanks to the Woodbrass team for their responsiveness and for retrieving the package sent to the wrong address. Tested directly via Bluetooth, pairing is immediate. You just have to get used to the touchpad, which is a bit confusing compared to the physical button; otherwise, it works perfectly, the sound is incredibly refined (understandable since it was formerly AKG), so logical, and the panorama is amazing. And I haven't even tested the hi-x55 or the x60, which is the top of the range, but already for the price, the precision is there. This brand will make great strides, at least among professionals; obviously, for the general public, it's Sony, Bose, and the like.
