The SA6 Ultra features a hybrid driver configuration, incorporating a dynamic driver and five balanced armature drivers. This driver setup allows for wide frequency response and exceptional clarity across the entire audio spectrum. The balanced armature drivers excel in reproducing precise mids and highs, while the dynamic driver adds depth and impact to the bass frequencies.
