The Headband Sleep Clinic -  

A sleep clinic experience for 1/200th the cost is what Earable Neuroscience promises with its FRENZTM Brainband. This wearable has multiple sensors to infer one's state of mind. It then provides the appropriate audio feedback via its bone conduction speakers to help a person improve their sleep, focus, and mindfulness.
In the above interview, filmed at CES2023, Earable Neuroscience CEO and Founder, Tam Vu, indicates that they hope for FDA approval in 2024. This could mean it would be a device covered by insurance at some point. In the meantime, it is available on their website for purchase. As he points out, beyond the potential health benefits, it also operates a Bluetooth headset.
