Bone conduction products are usually categorized into three groups:

* Ordinary products, such as [[hands-free]] headsets or [[headphones]]
* [[Bone-anchored hearing aid]]s and [[assistive listening devices]]
* Specialized communication products (e.g. for underwater or high-noise environments)

One example of a specialized communication product is a bone conduction speaker that is used by [[Scuba diving|scuba divers]]. The device is a rubber over-moulded, [[Piezoelectricity|piezoelectric]] flexing disc that is approximately {{convert|40|mm|in}} across and {{convert|6|mm|in}} thick. A connecting cable is molded into the disc, resulting in a tough, waterproof assembly. In use, the speaker is strapped against one of the dome-shaped bone protrusions behind the ear and the sound, which can be surprisingly clear and crisp, seems to come from inside the user's head.<ref>{{cite web|last1=Banks|first1=Lindsey|title=The History of Bone Conduction|url=http://juliawall.sites.gettysburg.edu/westpoint61/the-history-of-bone-conduction/users/765|website=gettysburg.edu|access-date=11 July 2015|archive-url=https://web.archive.org/web/20180715040318/http://juliawall.sites.gettysburg.edu/westpoint61/the-history-of-bone-conduction/users/765|archive-date=15 July 2018}}</ref>
