Relax and feel the stress of the day float away with Kohler's VibrAcoustic technology, available on all nine models of its Underscore bath line. Vibroacoustic is a technology-based sound therapy defined as hearing and feeling sound vibrations through the body. The baths are engineered to ease tension with a sound system that can be used as a standalone audio solution for the entire bath. Users can stream music and podcasts through the bath from a mobile device via hardwire connection or wirelessly with a Bluetooth receiver. Six transducers producing music/vibrations are placed surrounding the bath, allowing the bather to not only hear but also feel the music streaming in from one of the four preset VibrAcoustic experiences. Chromatherapy lighting is synchronized with the VibrAcoustic experiences and will also align itself with the rhythm of outside music.
