Ear tubes that were used to open the ear canal had some purpose.

Ones that were supposed to otherwise improve hearing are useless.

They were sold in their thousands to unsupecting customers. Some were even silver plated.

One design had a vibrating reed incorporated that was also absolutely useless.
