We didn't buy the whole package, but the OT used the headphones with the weird music (have you listened to it yet?!) during a lot of her sessions with our son. He was able to pay more attention with the headphones and music on. I think it blocked out the other distracting sounds (flickering lights, air conditioning, kids in other rooms, chairs scraping, etc.) He still has the hypotonia that is often associated with autism (he has autism) so I don't know about therapeutic listening affecting that.

He still likes headphones in general, though. He went through a period where he wore noise-blocking headphones, but now just uses them for listening to regular music or computer games.
