Helix Syn V produces quiet yet powerful vibration in an ultra-compact, hands- free design and can be used in two modes, powered and unpowered. Slightly larger than the original Helix Syn, Helix Syn V offers a unique experience in unpowered mode with fuller, more robust stimulation. Powered mode introduces 8 expertly tuned, preset vibration patterns at 3 levels of intensity for a total of 24 enhanced sensory experiences, utilizing a simple multifunction button control.
