LUNA by DUNU is the world's first pure beryllium rolled foil diaphragm flagship dynamic in-ear. As our flagship product, LUNA was tuned to a reference sound signature, deep and natural imaging, even and smooth from top to bottom, and maximised for extension at both ends. The result is the most supremely detailed, transparent, sumptuous sounding earpiece ever crafted by DUNU. It is our best representative of beryllium’s full sonic potential, and we are absolutely thrilled to have everyone experience LUNA.
