Dynaudio, a world-renowned Hi End brand, always makes people feel amazing every time it launches new products, especially the huge flagship speaker Evidence Master, which is already amazing just by static display. Another representative work of Dana, Confidence C4, also inherits the figure of the flagship speaker, with a tall and thin box and high-standard accessories. This time, Dana launched a C4 signature version. Of course, the C4 signature will not be just one more signature, and Dana has also made some improvements to the C4 interior.
