Hunter's comment
Necomimi cat ears it's a gadget controlled by the brain, which moves according to your mood.
They work with AAA batteries. You just place them on your head, then attach the ear clip, and the sensor on the forehead.
When you place them on the head, it will start to calibrate, trying to detect brain signals, it takes about 2 minutes.
What ear movement states mean:
- droop down slowly - relaxation;
- perk up quickly - focus or interest
Pros: combining new technology with fashion, easy to use, fun to wear, good price: $49.99
Cons: can become tiring after long wear.
