The Intensor has two controls situated conveniently between your legs. There is the expected volume control and an unexpected tactile intensity control. As you turn up the volume the vibration effects increase. You can fine tune the effects with tactile intensity control which controls the low frequency. In games you'll want to maximize the sound effects such as gun fire, car crashes and explosions while minimizing the effects from music.
Most games have a way to adjust the sound effects and music.
BSG Labs suggests setting the sound effects at maximum and the music at half volume. The chair also features a headphone jack which is convenient for late night gaming. Plugging in a set of headphones cuts the sound from the speakers but does not cut the tactile intensity. Just plug in a set of headphones, keep them off your head and crank up the intensity. Overall, the design of the chair is impressive.
