Previous page Next page Difference between SONA and SONA Cruise SONA and SONA Cruise have the same design with 8 different vibration patterns, with the main difference being in the added Cruise Control, which regulates the intensity and ensures there is no power drop-off when pressure is applied. Differences between all SONA models The difference between the first- and second-gen models is the additional vibration modes, a wider range of intensity, a softer silicone finish, and a broader mouth on the SONA 2 models. What is SenSonic technology? SenSonic technology is built around the use of sonic waves to allow vibrations to penetrate deeper and stimulate the entire part of a woman’s outer pleasure spot rather than just the surface level, as most classic massagers do.
