Bob's mention of a head massaging device

In watching the video about the eye massager that targets the temples, Bob mentions that he has a device for the top of his head for his tension headaches but doesn’t say what the device is. Is there a way to find out more about that device?
Thank you for your help!
So grateful for you guys!
