The Modius headset works by stimulating the vestibular nerve. You’ll probably feel a light tingling/pricking sensation behind the ears where the pads are placed, although this usually gets less noticeable as the body gets used to it.

As the vestibular system is responsible for balance in the body, it’s normal to feel a little unsteady when wearing the headset (which is why we recommend only using it whilst seated). You will probably feel a slight rocking or swaying feeling from side to side, with the sensation often likened to that of being on a boat or as though you’ve had a glass of wine.

Everyone’s sensitivity to the stimulation will be different, and it will likely feel different across sessions too – sometimes you’ll feel it more than others, and this could be due to differences in body temperature, humidity levels, time of day, slight differences in the placement of pads etc.

If you are prone to seasickness, it’s possible that you will only be able to tolerate a very low level of stimulation, although over time the body will usually become more tolerant to it.
We therefore recommend that you start on level 1 and see how you feel, only increasing the level very gradually. Give your body time to get used to the feeling. You don’t need to be at the highest level for it to be working – just stick to the level at which you can feel the swaying feeling yet it’s still comfortable for you.
