Who should buy which
Frequent transcontinental travelers wanting to pre-shift before flights, shift workers, anyone with delayed sleep phase who can't fall asleep before 1-2am, light-deprived northern-latitude workers in winter, founders with chronically-shifted Monday-morning starts.
You already use a 10,000-lux desk light box consistently and the desk-bound protocol fits your schedule. Or you have any photosensitive condition (migraine, retinal disease) - consult an ophthalmologist first.
Buyers who've already optimized sleep hygiene + tracking + environment (Oura + Eight Sleep dialed in) and still have sleep-onset latency or fragmentation. Buyers willing to commit to a 15-minute pre-bed ritual nightly. Researchers / quantified-self readers who want the most evidence-backed neurostim wearable.
You haven't yet fixed the basics (consistent bedtime, dark room, cool temperature, no screens in the hour before bed). The basics return 80% of the result at zero hardware cost, Somnee is the long-tail intervention, not the entry point. Also skip if you're sensitive to anything wrapped around your head while sleeping or in early-bed wind-down.
