Sleep doesn't always come easily, and there's no one fix for that. Calm Infusion is a ring you put on and mostly forget about — no charging, no app, nothing to sync — that may help with sleep and stress as part of an evening routine.

It's one design in four colorways — gold, rose gold, silver, and black — so it looks like jewelry, not like a gadget. Wear it during the day, keep it on at night, or make it part of however you wind down.
