The CapTune app is a player with integrated sound tuning, designed to provide music lovers and headphone users with individually optimised sound. The user benefits from Sennheiser’s know-how and algorithms without having to be an expert himself: using the SoundCheck function, he can compare sound variants with one another by ear, select them and store them in individual sound profiles. These settings are adapted to specific music and surroundings, enabling the user to activate his “perfect” sound for any situation with a single click. But there are other, equally simple ways for him to find his own “perfect” sound: the frequency response curve, the equaliser sliders and the effect controllers. CapTune works with music from various sources (streaming, local storage devices etc.), making it child’s play to create and manage multisource playlists.
