Owlet Smart Sock 3 is better than Smart Sock 2 and the extra $50 is worth every dollar. In summary, Owlet Smart Sock 3 is better than the Owlet 2 (V2) when you consider the consistency of readings, the magnetic wireless charging that is fast, the improved sleek design, the improved technology, and the improved sleep trends data.

I should explain that about a year after Owlet Smart Sock 3 (V3) was released FDA insisted that Owlet should seek FDA clearance as it classified it as a medical device. Almost 2 years later when Owlet Smart Sock 3 was relaunched with Babysat device, Owlet entirely discontinued the V2 Sock.

That said I have given details of how the V3 Smart Sock was improved compared to the V2 model.

I’ve explained in detail below:

First, you’ll like and perhaps appreciate getting readings consistently from your baby even when the baby’s feet are in gentle motion (wiggling), thanks to Owlet Smart Sock 3’s super-sensitive sensor. On Owlet Smart Sock 2, you will not get any reading if your baby is wiggling or having any gentle motions and I’ve personally had to wake up at night to go check on the baby. To me, this was a huge differentiator as it helps to get those readings on time when you need to.

Secondly, Owlet Smart Sock 3 has a magnetic wireless charging of its base station which is new to all baby monitors. I do not know of any other brand that uses magnetic wireless technology and I have reviewed a good number of Owlet alternatives. With Smart Sock 2, you need to plug in your base station to charge, and most of the times when I used Owlet Smart Sock 2, I’d forget to plug in – the fact that it requires you to use my two hands to plug it in, makes it harder when you are occupied and therefore easy to forget.

Owlet 3 can fully charge in 90 minutes, half the time you need to charge Owlet Smart sock 2, and in my experience, a charge of 20 to 30 minutes will suffice for most of the night. So, even when I forget to charge until it’s a few minutes to bedtime, I can still get a good amount of charge in 20 minutes. On the other hand, Owlet Smart Sock 2 requires 4 hours to fully charge! However, If you forget to charge on time, you’ll be woken up by annoying low-battery notifications at 3 or 4 am when the battery goes below 20%.

Thirdly, Owlet Smart Sock 3 has an improved design compared to Owlet Sock 2. Owlet 3’s sleek design is much smaller than Owlet smart Sock 2 as shown in the diagram below:

Another significant difference between Owlet 3 and 2 is sleep trends and insights. The third generation Owlet Sock has improved sleep trends data compared to the older Smart Sock 2. You’ll get data on your baby’s sleep quality such as the hours the baby slept, the number of waking hours, among others.

What was Owlet Smart Sock 1 vs 2?

The Owlet Smart Sock 2 was introduced 17 months after its predecessor, the Owlet Smart Sock 1. The second generation brought significant improvements in design, accuracy, and app functionalities. With its enhanced design, the Owlet Smart Sock 2 fits securely on a baby’s feet, minimizing false alarms. In contrast, the Owlet Smart Sock 1 often fell off, leading to multiple false alarms.

What was Owlet Smart Sock 3 vs 2?

Firstly, the consistency of readings has greatly improved with the Owlet Smart Sock 3. The new sensor placement and improved technology have resulted in more accurate readings, giving parents peace of mind. Additionally, the updated base station now has a sleeker design, taking up less space on a bedside table.

Furthermore, the Owlet Smart Sock 3 offers new data tracking capabilities. Parents can now view their baby’s sleep trends over time, helping them understand their little one’s sleeping habits and make adjustments if needed. The app also has a “trends” feature, which compares their baby’s sleep patterns to recommended guidelines by age.

Finally, the Owlet Smart Sock 3 also offers a new feature called “Connected Care.” This subscription-based service allows parents to track their baby’s heart rate and oxygen levels in real-time from anywhere, giving them added peace of mind and convenience.

In summary, while the Owlet Smart Sock 2 was already a significant improvement from its predecessor, the Owlet Smart Sock 3 took it to a whole new level with enhanced accuracy, data tracking capabilities, and the addition of “Connected Care.” It continues to be a popular choice among parents for monitoring their baby’s well-being.

What's the differences between Babysat vs Dream Sock?

While both BabySat and Owlet Dream Sock are FDA approved, they have minor difference. BabySat offers real-time vital sign tracking, but it differs from Owlet’s Dream Sock as it is exclusively available through prescription. This unique solution enables healthcare providers to customize and adjust alarms for oxygen saturation and pulse rate, tailored to meet the specific needs of infants.

Owlet Smart Sock 2 vs 1:

Owlet Smart Sock 2 was released 17 months after Owlet Smart Sock 1 and the major difference between the first and the second generation is design, accuracy, and app functionalities. Owlet Smart Sock 2 has a better design and fits well to the baby’s feet without falling resulting in fewer false alarms.
