ASTRA GO4 is a medical device that stimulates neurons by slight impulses made through a specific position on your skull.

We combine 4 different technologies to bring you into different states of mind within a few minutes-long meditations. Effects are long-lasting.

Studies have shown no negative effects on health within the metrics used in ASTRA over a long period of time while they have proven the benefits of using this technology on numerous devices including military research documents.

tDCS, tACS, tPCS are all used to stimulate neurons in our brain and thus effectively put you into the desired state of mind.

Bone Conduction is, on the other hand, used to bring you into a comfortable state while amplifying the effect of tDCS, tACS, TES.
