Here’s something I didn’t know until I became a NICU parent: In the United Position, one in 10 newborns are born prematurely. Countless preterm babes require a NICU stay, with the average length being 13. 5 days. Though I had little feeling of what I was doing when I impart residence my twins from the NICU, I did know that I was going to continue to monitor their vitals stats use an Owlet sock. The two partners and I had become accustomed to checking their heart rate and pulse ox ranks on a hospital observe, and being able to get that knowledge at home helped us build confidence in our character as non-professional custodians to two very tiny humans.

In both the NICU and online parenting gatherings, several people recommended the Owlet. It’s precisely these devotees the brand was responding to with the recent release of $359 Smart Sock Plus, a larger sock with an updated algorithm that can be used on children up to five years old or 55 pounds. That’s a reasonable move from the previous 18 -month/ 30 -pound cut-off that my teenagers simply delivered. The companionship claims that 72 percentage of both parents it polled said they’d like to use their Smart Socks for longer, and that certainly included me.


The third-generation Owlet monitoring system boasted a redesigned “butterfly” style sensor that fit into an updated fabric sock, and it’s more of the same with the Plus. You’ll find the same removable sensor with a jut button that attaches to the Base Station for wireless charging when not in use, along with the same winged, Velcro affections for switching it between socks.

It’s too still lightweight, easy to remove and change, and fast accusing. Owlet says a full blame takes an hour and a half, and you can get eight hours worth of use with exclusively 20 minutes of charging. That abide out in testing when I was able to grab a full night’s value of battery life in the time it took to finish our bedtime procedure with the kids. The compact, more slight Base Station is also the same as the one found on the smaller smart sock model.

The brand-new sock has a similar structure, more, including a soft, adaptable fabric strip that fastens around the ball of the foot to keep the sensor at the outside of the little toe. And there’s an ankle banding to secure the whole thing in place. The Smart Sock Plus comes with the same four initial sock sizes: left and right for under 12 pounds; and left and right for 12 to 30 pounds; plus an expansion pack of left and right socks for 30 to 55 pounds. It’s worth noting that currently the Smart Sock Plus is only available in the classic Mint Green shade, and not the Deep Sea Green or Dusty Rose colors.

I had issues with the fit on the last sock, and was pleased to find that the Plus version for large kids( 30 -plus-pound) seemed less prone to unintentional slippage. I say unintentional because my boys have just learned to work Velcro so we are to be able to, very purposefully, make the sock off. While they were proud of themselves for their attainment, this underscores the challenge in furnish a sock for older children: It might be a fight to get them to keep it on.

One of the user revaluations I speak for the original Owlet sock recommended putting a regular sock on over the smart-alecky one to keep it from sliding around. I tried that and found that it worked well for my lad, but less so with my daughter who has better dexterity. That’s unlikely to solve the issue for the length of the sensor’s life, though I’d expect older children can be taught to wear the sock to sleep. I requested Owlet what they recommend to keep the sock in place in these instances, and they, more, recommend using a regular sock or footie pajamas. They too claim some mothers wait until their boys are asleep to give the Smart Sock on, but those kinfolks are braver than I.

Because the sock fits better, I had fewer disconnection error notifies. In knowledge, the only time I received alerts due to a misaligned sock were durations when my babies are really removed it. Given that frequent unexplained alarms represent one of my sting pitches with the last version, it was nice to see that had improved. I got consistent sees when they were in fabric socks or footie pajamas, and too when they were under a cloak. What’s more, I had no problem keeping the Base Station in my power, next door to my kid’s room; it was still easily able to keep everything connected.

I will say that the sock still seemed to run out of battery quicker than the second-generation one did, but it was comparable to the third gen. While the sock could reliably make it through an night of observing( approximately 7pm to 7am ), I rarely accompanied low-battery cautions in the morning. Nonetheless, these notifications was mentioned that I had less than four hours of runtime, which seems like plenty of time.


Every time I set up an Owlet device, I touched a snag. This time, instead of connecting to the Owlet in my WiFi defines, I was instructed to go through the Privacy positions and toggle on the Local Network option. But the Owlet app prevented telling me to check the permissions, even after I’d turned them on. And off. And on again. And closed and restarted the app.

Although this is the first time I had to call Owlet support for a resolution, I was able to easily get through to a live person and resolve the problem in a bit over five minutes( thank you again, Jill !). I haven’t had any problems since.

As with the rest of the Plus experience, the app remains largely unchanged. The divergence here are the updated algorithms that Owlet is using to calculate data for kids in the 18 -month to five-year range. Because the sock can now fit more babies, the algorithm has to accommodate for physical changes over time. Owlet says a good example is heart rate, which alters as small children gets older.

Aside from that, you still get a dashboard to access each child’s profile, which contains their live heart rate and pulsate ox data, the battery life of the sock and WiFi connection status. If you’re also applying the Owlet Cam as a video check, you’ll examine the feed now. Previous days’ data can be found under History, which includes an overview and info graphs. This has always been one of the most useful portions of the app for me, as it showed me the trends on when my twinneds were — and were not — doing well sleeping.

As I mentioned, I haven’t more had any false alarms, though I’m not sure what to chalk that up to — faster internet at my brand-new room? A better fit on the sock? Upgraded algorithms? Either way, it’s nice to report on a better knowledge, especially given the price difference between the $359 Plus and the $299 third-gen sock.

The competition

There aren’t a ton of products out there same to Owlet’s sock. The busines has seemingly cornered world markets on child wearables that measure pulse ox and heart rate, but there are a few other noteworthy inventions in this space. One of them is the Nanit structure, which duets a camera with an part of the company’s Breathing Wear clothing to monitor respiration and sleep as well as offer a video feed. The Complete Monitoring System, which includes app subscription addeds like two days of video autobiography, comes in at $379. In testing, the Breathing Wear made as advertised and the camera offered an impressively clear 1080 p HD feed. I’ve also worked the Pampers Lumi, a solid $187 camera-slash-wearable that exclusively tracks napkin changes and sleep patterns. Nonetheless, it looks like the sensor is hard to come by right now — we’ve reached out to Pampers to see if the Lumi sensor and comrade diapers are still widely available.

Owlet Smart Sock Plus OwletWrap-up

The Owlet Smart Sock Plus replenishes a need for people who are already on the Owlet bandwagon: It lets mothers to continue using a commodity they like and are comfortable with for a longer period of time. Other than better algorithms and a larger sock, there’s not much difference between the Plus and the third-gen device — which was absolutely an improvement over the version that came before it. I’d expect the $69 stretch compres to sell well, as it provides what current clients will need to upgrade to the next sock degree, but $359 is a high barrier to entry for a babe monitoring work that may not work for your sleep chore. That said, if you’re an Owlet customer who is happy with your current smart sock, it’s unlikely you’ll regret snagging an expansion pack when your kiddo has gotten big enough.
