This study tests if special earbuds called NextSense EEGBuds can tell when someone falls asleep. Normally, doctors use a machine called an EEG (electroencephalography) in a lab to check sleep. The EEG uses sticky pads on the head and is very expensive and time-consuming. These new earbuds might make it easier and cheaper to check sleep at home. People with sleep troubles like narcolepsy (a condition causing sleepiness) will try the earbuds with and without their wake-up medicine. This will help check if the earbuds work as well as the lab test.

• Two visits are needed, happening within 16 days.
• No cost is mentioned, but you'll need to stop taking wake-up medicine for part of the study.
• Risks: You must be okay wearing earbuds and have no other serious health issues.

If you are 18-60 years old with narcolepsy or similar conditions, you might join. But, you can't join if you have other sleep problems or serious health issues. This study could help make sleep tests easier in the future.
