    This sock makes my life smoother and easier. It wasn’t very easy to set it up, o couldn’t connect with the wi-fi but husband fiz it for me. App is very easy to use. Monitor is very accurate, I can monitor her heart rate, oxygen levels and her sleep. If anything starts going “wrong” with her the app send notifications. Comfortable and soft material. Battery charges very fast and lasts almost 2 days.

    Amazing product.

    This is a very well specified and technical baby monitoring system. It basically monitors your child’s vitals via a wearable ‘sock’ which constantly records information and then relays it back to the user via the app. The sock itself is comfortable and adjustable and is charged via a dedicated docking station. The App is well designed and intuitive to use and the warnings and notifications are clear and concise.

    It is a premium and expensive product, but it is fully loaded and gives real assurance to you as a parent that it is monitoring you child effectively.

    This is a really good idea and really useful for babies that have medical conditions, breathing problems, high colic, asthma and other medical conditions to help keep close track of your babies oxygen levels , heart rate and sleep patterns all through the readings from a comfortable sock that is soft and comfortable and doesn’t bother a baby one bit as they are very easy to fit , feel super soft and you get a number of socks to change as your baby grows , so the owlet Smart Sock Plus can be used as your baby grows.

    It does seem a tad expensive for providing data that cheaper devices can provide , as in smart watches, fitness trackers , but everything does seem well made and I’m sure there is technology built in that must justify the high price tag.

    The Smart Sock technology and alert system will give you peace of mind and alert you of any sudden changes in oxygen, heart rate or your baby being unsettled in the night, especially with Ill babies with certain medical conditions, but it’s also great to use as a general baby monitor, you need to pair it with your home WiFi and phone to get the absolute best from the device to analyse data and analytics and other things.

    It’s definitely a good device to provide peace of mind for nervous parents or to monitor health conditions and to be alerted quickly if needed.

    It gives you more in-depth information than what using just a baby monitor camera and sound monitor would give you so you definitely know if something is bothering your baby which is excellent, so this type of device will definitely appeal to parents with babies susceptible to breathing problems, heart problems to keep a close eye on them for peace of mind.

    It’s well made and interactive and the socks are comfortable and easy to put on, change.

    But it’s quite expensive but it could prove invaluable to some people, overall its a very clever design and a useful baby monitor.

    First impressions when opening the box is very good, the quality and the attention to detail in the packaging is very impressive you do feel like you are opening something special.

    That is where the experience starts do go bad, no instructions other than a card to say download this app (no QR code to make this process easier). You need to register (no idea why they need my mobile or date of birth for this device). The email to register will more than likely go into your junk folder so check that. Once they have confirmed you are who you say you are you then enter the set up for your child, age, weight, gender etc (you can even add a picture if you like).

    Then its just a case of following the instructions.

    Then comes setting up the sock, the sock and your phone need to be on the same Wi-Fi network, you need connect the base unit to your Wi-Fi network and this is where I hit my roadblock. The base unit was powered up and even played music at one point. There were no instructions on how to connect or what colours you should have on the base station. This took some time and several attempts, I moved right next to my router which seemed to work. Now once connected to the Wi-Fi you need to register the base station to the app (this even says it “can require multiple attempts”!!!).

    This is where clear instructions would come in useful, hold down the button on the bottom of the base station till you get too beeps, what you get is you get a bleep bleep then after a few seconds a beep beep. Then you need to pair the sock with the base station which was the easy bit.

    The fact your phone and the base unit need to be connected to the same Wi-Fi means this is no good for the traveling parents.

    The sock feels very soft to the touch and I’m going to try on my 3-year-old for a few nights and update my review when I have tested on a child.

    The build quality and the design are of high quality I can’t fault the build or the design, however the question is does the price for what a Fitbit is basically, warrant the high price tag. As a parent with so many other costs I don’t see this being high on my priority

    No good for the traveling parents as Wi-Fi is required.

    This item is just great for piece of mind. It’s easy to use, mostly easy to put on baby (unless you have a kicking fight on your hands) and monitors everything you have a concern over whilst they’re sleeping. How well it stays on is one thing as sometimes your little wriggle monster may be able to push it off, causing the alarm to sound. Personally I would rather have the reassurance that it’s there and know that if it goes off it could be nothing, but also could be life saving.
    The battery life is absolutely fine and it has a wireless charging dock for ease. I tend to charge it every day, but that’s because I don’t want it giving up in the middle of the night.
    Each sock provided of different sizes has the same monitor which is helpful and easy to change over, although I’m not sure all toddlers or older children would be happy to go to bed with it on without a fight. There are probably parents out there that actually really need to monitor these vitals for medical purposes, so I expect for them this is fantastic.
    It only comes in one colour, but I personally like it, and think it’s nice and neutral/unisex.
    The price does seem a little excessive, however at the same time if this lasts as long as it’s suppose to you’re paying 340 to cover monitoring for 5 years, which doesn’t seem as bad.
    I hope this helps with your purchase

    Good gadget for piece of mind

    The Owlet Smart Sock is easy to review but hard to ultimately recommend at the price. I think it is a great idea and gives parents peace of mind. There are plenty of horror stories of infant cot deaths. Deaths that are unpredictable and not well understood. There are countless other health and developmental issue that I can see driving a parent to want a device like this. Being able to monitor aspects of your child’s vitals is very valuable. It could literally be a life saver. The issue is whether this product is worth its price regardless of the use case. Is the underlying tech worth the asking price?

    The device itself is well made and easy to setup. The system comes with an add-on pack that allows you to use the smart sock on children up to 5 years of age. It’s basically a bunch of extra different sized socks to put the monitor into. My 4-year-old is never going to keep this on his foot overnight and didn’t when I tried to test it with him. I think I would have to sneak in once he falls asleep and strap it on him then. 😉 However, I appreciate that such an able bodied and active child is probably not the target demographic. For younger children this is perfectly suitable. I’ve also tested this with a ~6 month old. Wireless charging is also a great addition but something that you should expect at this price.

    The app is well made and easy to use. It worked fine for me. I am aware of some that have had connectivity issue and problems getting notifications. I did not experience these issues. Hopefully, things will continue to run smoothly on this front. I’ll update the review if I start to encounter any issues.

    My final rating is that it is a fantastic product. I can see plenty of use cases where this is ideal. I can see this being an absolute necessity to certain parents / parents of certain children. And it is impossible to add a monetary value to the peace of mind it would give those parents. However, I can give a monetary value to the tech inside the hardware. I can give a monetary value to the app development. I can give a monetary value to the backend server infrastructure required to support the system (users and notifications etc.). I’m just not yet up to the price that is being asked for it. I expect a bit of a premium due to the use case. I just think it is a little overpriced. I’ve gone for four stars as it is really good other than the price.

    Fantastic product - perfect but for the price

    A smart sock baby monitor, that monitors a baby’s heart rate, sleeping trends and oxygen levels.
    The set comes with a charger disc and three sizes of sock bandages, to fit the monitor to the baby’s foot. It also has USB C charging and a UK and continental style slot together mains plug, but no instruction book, you have to source this out on the internet, so if you don’t have internet, you’re stuck. They could have at least included a quick guide, seeing how much you have just paid out for this device.
    When I tried typing in the the web address to get the instructions, I was met with a notice that the page could not be found, what a great start, if I’d have paid 340 I’d have sent it straight back at this point. But let’s carry on, seeing as I’m reviewing the device. This was the America site, I transferred over to the UK site, and no instructions there either.
    Let’s try the UK support web page, still nothing, in fact I search the whole of their web site and no mention of a user guide. I did find a troubleshooting guide on the US site, but still nothing that I would call a basic instruction and set up guide.
    I then did a web search and found it, unfortunately I cannot put a link here, as it’s against amazons rules reference reviews.
    I then downloaded the app, to see if maybe there is a set of instructions on there, but of course first thing you have to do is register for an account, and as I got this for my son and his new daughter, I don’t want to register it to me, in case that causes problems when I hand it over to him, ie do I have to de-register it, for him then to be able to register it in his name, again a set of instructions would have helped.
    But now I have the user guide, I can take you through the set up and how it works.

    “The sock sensor uses pulse oximetry to get readings from your baby’s foot while they sleep. A small red light shines through the skin and the amount
    of blood flow and oxygen levels are estimated based on how much light is transmitted to the sensor.
    The sock sensor collects the data and sends it to the base station.
    The base station notifies you, as needed, based on the data sent from the sock. The base station is your primary notification device, in the event of a red notification and as such should be placed in a location where you can hear it, if it sounds the alarm.

    To use LAN mode, your phone must be on the same Wi-Fi connection as your Base Station. Using Wi-Fi, the app establishes an initial connection to the Owlet cloud and will deliver data to the app, as long as the app is not closed and the Wi-Fi connection does not change on the app or Base Station.

    The Owlet smart sock requires access to an iOS or Android device, with
    the Owlet Care App downloaded; minimum OS versions apply, see app stores for details.
    The Smart Sock works on baby’s up to a maximum of 30 lbs, this is very important.
    A 2.4 GHz wireless internet connection is required for live readings in the Owlet app, remote access to the app and some app features. HotSpot WiFi and 5 GHz are not supported, so you may have to turn off your 5GHz on your home hub, until you have made a connection during set up, then once connected, you can switch your 5GHz back on. It’s much the same with all smart devices, ie smart bulbs etc”.

    Once you have installed the app, follow the instructions on screen and register the device. Once you have paired the device to the base station, place the sock transmitter onto the base station to charge it, the base station will pulse white to show its charging. If the sock needs updating, it will carry this out now, so leave it connected until this has finished.
    A full charge takes 90 min, and this will give you a 16 hour battery life.
    You get 3 sock sizes, and it’s important to use the correct size as per your baby’s weight. Size one is up to 12lb, size two from 12lb – 30lb and size 3 from 30lb – 55lb, and you get a left and right sock for each size.
    The instructions take you though the fitting of the sock on baby’s foot, as certain parts have to line up to get the correct fit, so the device can take correct readings.

    The base station communicates via different coloured lights:-
    Bouncing green: It’s updating its readings.
    Pulsing green: The readings are within the normal range.
    Flashing blue: The sock is out of range of the base station, the battery is depleted, or the signal is being blocked.
    Flashing yellow: The sock is improperly placed on the foot, or has fallen off.
    Flashing red: The heart rate or oxygen levels are outside of the preset range.
    Pulsing white: The sock is charging.
    White: The sock is fully charged.
    Bouncing white: The sock is not paired.

    To switch the sensor off, ie to stop it glowing red, remove the sensor from the base station, and disconnect the USB cable. Then press and hold the base station button, while re-inserting the USB cable, hold the base station button until light glows orange and you hear 4 beeps. Then tap the button once and the light in the sock will turn off. To turn the Sock back on, place the sensor back into the base station charging port.

    The sock can be hand washed with a mild detergent and air dried. Frequent washing is recommended, to not cause a rash on baby’s foot.

    Once we got over the initial problems of no instructions, the set up was pretty easy, it was a bit touch and go setting the sock setup on my granddaughter, as she’s 6 months and not used to it, but once you line up the notch with the little toe, as the instructions state, we got there in the end.
    I will update as we go along, and let you know of any problems we encounter.

    No instructions included, you’re left to track them down yourself.

    Piece of mind!! I am a mother of two young children. My oldest is now 3 but prior to his I experienced a miscarriage, so when I got pregnant again the Owlet was one of my first purchases. I used an older version of the sock with him until he was 18 months. I love the updates to this new Owlet sock. The design of the sock itself has a much better snug fit. I like to put my baby in footed pj’s to also ensure it doesn’t come off. I also like the smaller design of the unit itself. The old version would light up my entire bedroom and sometimes would affect my sleep. This version is much smaller so it is much more tolerable in a dark room. The Owlet is a must buy product for me. It allowed me to sleep peacefully.. or as peacefully as possible with a newborn, without having to worry if my baby was breathing or not. I love that it comes with all 3 sizes for the sock and that you don’t have to purchase those separately. Anytime a new mom asks me for baby “must haves,” the Owlet is alway the first product I recommend.

    I had a difficult time with my first baby, she was a happy wee thing but seemed to get poorly a lot. It culminated in a month of hospital visits and there is no doubt in my mind that medical professionals were dismissing my concerns as nothing more than new mum worries and given my daighter’s track record added to that. This product was recommended to me by a friend when I had my baby boy and what a difference it has made to my wellbeing! Happily my son has not been half as unwell as his sister but thanks to this, I have data I can reference when talking to professionals and most importantly (I think anyway) I can reassure myself that just because he’s a bit grumbly doesn’t mean anything to worry about. The sock takes a bit of practice getting into the right position, but once its on its grand. My one criticism is that the alerts can be shrill and annoying, but better that than worrying.

    I purchased the owlet prior to the birth of my Son. I was worried that I’d be unable to sleep, worried about his breathing. The owlet has been great to help reduce that worry. We use it every night and at nap times if I’m also wanting to sleep. The battery lasts a long time (around 16 hours) and charges quickly. It is easy to set up and relies on home WiFi. I even took it on a recent hotel stay and it took 1 minute to set up.

    The only area I think it lacks is the analytics you can see the next morning. The sleep graph often shows sleep when I know my son was awake or vice-versa. Also, the graphs only show 10 minute blocks. The sock captures data constantly so It would be good to be able to see all the data.

    I know other reviews have mentioned the base station giving false alerts, but we haven’t had any.

    – Good fit of sock
    – Easy set up with home wifi
    – Good battery life
    – Peace of mind

    – Expensive
    – App analytics and navigation could be improved

    We have had quite a poorly newborn with RsV Bronchiolitis and a few weeks later covid- both requiring hospitalisation and oxygen. This product gave me such peace of mind when she was asleep that she was ok.
    I found the app easy to use and when there were issues with sock placement and connectivity they were easily rectified.
    I wouldn’t be without one now

    We got this before our baby arrived. When we got him home it was difficult to fit on a small newborn, so we left for a week or so and he got use to it. Need to ensure good fit as the alarms scare you to death. Some red marks but putting on secure as wriggly. Hoping will be of more use as we go on. A level of reassurance but be confident with technology and don’t panic about the readings. Very expensive for what it is but appreciate the technology inside. Make sure you have good WiFi !

    I love the fact that you can check your babys stats in a few seconds, it also tells you if they are awake and wriggling. I sleep a lot better at night knowing that it will alert me if there is anything wrong!

    Golden Review Award: 4 From Our UsersOut little boy was taken off to ICU hours after birth with dropping oxygen levels. He wasn’t in there all that long (10 days) but if left my partner understandably anxious. This was particularly bad at night. We agonised for a while whether this would be worth the money….well would you pay 279 for a “good” (relatively speaking) night’s sleep with a new born??

    I still believe this device has an incredibly small impact on chances of SIDS, but the psychological advantage to my partner knowing something was there monitoring his oxygen made that irrelevant.

    The app is very well put together, the device seems very accurate (although I guess I’ve no medical o2 monitor to compare!). The battery life is great, the different alarms are great so you don’t panic if it’s a device issue.

    It’s surprisingly easy to place on the baby, even when wriggling and it really doesn’t seem to bother out little guy at all.

    Money well spent, especially if you have a little extra newborn anxiety!
