Owlet Smart Sock 3 Baby Monitor, Mint - Brand New

The Owlet Smart Sock 3 uses reflectance pulse oximetry on top of the foot to read real heart rate and blood oxygen, rather than inferring them from movement. Readings appear live in the free app, and the Base Station lights and sounds an alert if either falls outside the preset zone.

Four fabric socks in two sizes cover 5 to 30 lb, so one Owlet Smart Sock 3 kit lasts from newborn to around 18 months with spares while others are in the wash. The sensor runs up to 16 hours per charge and drops onto the base to recharge, with a 20-minute top-up buying roughly eight more hours.

Every baby monitor we list is checked in our Toronto shop before it goes on the shelf, so what arrives is what the page describes. This Owlet unit is stocked and ships from within Canada, which keeps delivery short and avoids surprise customs charges at the door. If you are weighing it against another model, our team takes questions by phone or email and can tell you exactly what is in the box before you commit. Orders placed on business days leave the same day wherever stock allows, and in-store pickup is available in Toronto if you would rather collect it yourself.
