This study tests special **NextSense EEGBuds**, a type of earbud that can tell when someone falls asleep. It's checking if these earbuds work as well as the usual method used in a lab, which is called **electroencephalography (EEG)**. EEG uses small sensors on the head to check brain waves. The study is for people who have trouble staying awake, like those with narcolepsy or idiopathic hypersomnia. These are conditions where people feel very sleepy during the day. Participants will try the earbuds once while taking their usual wake-up medicine and once without it. There will be two visits to the study center, and they will be 16 days apart.

• The study lasts for 16 days with two visits.
• Participants must be 18-60 years old and already diagnosed with certain sleep disorders.
• Some health conditions might prevent you from joining, like certain psychiatric disorders or infections.
