Foam earplugs and an eye mask
Instead of sleep gadgetry
~$15 against $100 to $400
Both aim at the same two inputs. One of them removes those inputs directly.
Randomised trials in coronary and intensive care units have tested this pair against usual care and found better sleep quality, with eye masks raising overnight melatonin against control. Light and noise are the two things the expensive devices measure, model and report back to you in the morning. Blocking them costs fifteen dollars.
Those trials ran on hospital wards, where noise and light are the problem being solved. A quiet dark bedroom has far less to gain, and neither of these touches a sleep disorder. Foam plugs need replacing, and a side sleeper will find them sore.
