Owlet vs Eufy Baby Monitor: Which Smart Sock System Protects Your Baby Best?

Based on clinical studies, Trustpilot reviews, expert testing from BabyGearLab, and thousands of real parent experiences

The short answer: The Eufy Smart Sock S340 wins for most parents with its superior 2K video quality, longer 24-hour battery life, easier setup, and $120 lower price point—all without requiring a subscription. However, if FDA clearance and medical-grade accuracy matter most (especially for preemies or high-risk infants), the Owlet Dream Duo 2's clinical validation is worth the premium.

The Death Match: 6 Rounds, 1 Winner

We're scoring each round from 1-10. Higher score wins the round. Let's fight!

Round 1: Video Quality

Both monitors let you watch your sleeping baby, but the difference in clarity is immediately noticeable. The Eufy S340 shoots in 2K resolution—the only baby monitor in its class to offer this—delivering crisp detail even when zooming in on your baby's chest to check breathing. Users consistently praise it: "The video is sharp, even in night mode. You can hear the baby breathe softly without static or delay" (Parenthood Adventures).

The Owlet Dream Duo 2 offers solid 1080p HD video with 4x zoom and wide-angle view. It's perfectly adequate, and the night vision auto-adjusts well. But compared to Eufy's 2K, you're getting yesterday's tech at tomorrow's prices. Owlet's Gen 3 model does offer 2K, but that'll cost you $549.99.

Round 1 Winner: Eufy — 2K resolution at a lower price point is hard to beat

Score after Round 1: Owlet 7 | Eufy 9

Round 2: Health Monitoring Accuracy

This is where Owlet pulls ahead significantly. The Dream Sock is FDA-cleared through the rigorous De Novo pathway, meaning it was clinically tested for oxygen saturation accuracy across all skin tones (Fitzpatrick Types I-VI) under both motion and non-motion conditions. According to Owlet's clinical data, accuracy is within +/- 3% of gold-standard arterial blood gas measurements (Contemporary Pediatrics).

A 2023 NICU study comparing the Owlet Smart Sock 3 to hospital-grade Masimo pulse oximeters found strong correlation in both heart rate and SpO2 readings. Sensitivity for hypoxemia detection was 88.8% (PMC/NIH).

The Eufy Smart Sock S340 tracks heart rate, blood oxygen, and sleep patterns through its app—but it lacks FDA clearance. Some reviewers note "the sensor can sometimes provide erroneous vitals when the sock isn't properly positioned" (BabyGearLab). If you're monitoring a healthy full-term baby, this may be acceptable. For preemies or infants with health concerns, the FDA clearance matters.

Round 2 Winner: Owlet — FDA clearance and clinical validation provide real peace of mind

Score after Round 2: Owlet 16 | Eufy 15

Round 3: Setup & Reliability

Setup experience couldn't be more different between these two. The Eufy Smart Sock was praised by users for being "setup in a flash with no issues. It fits well on the baby's foot, charges quickly, and tracks heart rate, blood oxygen, and movement" (Affisecure). One reviewer noted the signal "never cuts out, even from the far end of the house."

Owlet's setup experience is a different story. Multiple users report frustration: "The sock base and video monitor are horrendous to set up. Taking hours on multiple days to configure each. The app freezes continuously and is slow to open the camera" (Trustpilot). The monitor only works with 2.4 GHz networks, and users must sit close to the router during initial setup.

Worse, WiFi disconnection is a recurring theme in Owlet reviews: "The Owlet frequently disconnects, leaving me hanging. I never know when this is about to happen, so sometimes I have to make the difficult decision to go disturb potential sleep or just be OK with not seeing the monitor" (Trustpilot).

Round 3 Winner: Eufy — Reliable setup and stable connections matter at 3 AM

Score after Round 3: Owlet 21 | Eufy 23

Round 4: Battery Life & Charging

Battery anxiety is real when you're monitoring your baby's vitals overnight. The Eufy S340 dominates here with 24 hours of battery life on a single charge, and it only takes 2 hours to fully recharge. The magnetic charging base makes it effortless—just drop the sensor and go.

The Owlet Dream Sock lasts about 16 hours on a full charge with a 90-minute recharge time. That's adequate for overnight monitoring, but if you forget to charge it one evening, you might find yourself without monitoring at 2 AM. The 8-hour battery advantage for Eufy means less charging anxiety overall.

Round 4 Winner: Eufy — 50% longer battery life means fewer charging interruptions

Score after Round 4: Owlet 27 | Eufy 32

Round 5: Value for Money

At $399 for the Owlet Dream Duo 2 versus $279.99 for the Eufy Smart Sock S340, we're talking about a $120 difference—roughly 30% more for Owlet. What do you get for that premium?

FDA clearance is the main differentiator. The Owlet also offers Owlet360, an optional subscription for extended video clip storage (48 hours free, upgradable to 14 days). The product is HSA/FSA eligible, which could effectively reduce the cost for many families.

Eufy requires no subscription, ever. All features are included at purchase. You get better video quality (2K vs 1080p), longer battery life, and a more reliable setup experience. The S340 also includes a physical parent unit in addition to app access—Owlet is app-only.

For a healthy full-term baby, the Eufy delivers more tangible value. For a high-risk infant where FDA-validated accuracy is non-negotiable, Owlet's premium makes sense.

Round 5 Winner: Eufy — More features, better specs, and $120 less

Score after Round 5: Owlet 33 | Eufy 41

Round 6: Customer Service & Trust

This round is brutal for Owlet. On Trustpilot, Owlet Baby Care holds a 1.6 out of 5 stars based on 187 reviews, with 80% being 1-star ratings (Trustpilot). Common complaints include products failing after 3 months with warranty issues, support chatbots that can't help, and difficulty reaching human support.

One representative review: "Terrible customer service from Owlet—parents, beware! We reported a fault with our Owlet Smart Sock 3 about a month ago because it wasn't working properly and kept setting off false alarms" (Trustpilot).

Eufy, backed by Anker (known for quality electronics), has a stronger reputation for product durability and customer support. The parent unit is described as "well-constructed and durable, with a clean aesthetic" (BabyGearLab). While no baby monitor company is perfect, Eufy's track record inspires more confidence.

The Winner: Eufy Smart Sock S340

The Eufy Smart Sock S340 wins this death match with a decisive 48-37 victory. For most parents, it delivers what matters: crystal-clear 2K video, reliable health tracking, 24-hour battery life, effortless setup, and a price that doesn't require a payment plan. No subscriptions, no WiFi drama, just solid baby monitoring.

Owlet's only meaningful advantage—FDA clearance—is significant for a specific audience but doesn't justify the $120 premium for healthy full-term babies. When you combine inferior video quality, shorter battery life, widespread connectivity complaints, and abysmal customer service ratings, the Dream Duo 2 struggles to justify its flagship pricing.

The numbers don't lie: 80% one-star reviews on Trustpilot for Owlet versus Eufy's stronger reputation backed by Anker's quality electronics legacy. For peace of mind at 3 AM, you want a monitor that actually works.

When the Loser Actually Wins

The Owlet Dream Duo 2 isn't right for everyone, but it's the better choice if:

Your baby was born premature — FDA-cleared monitoring with +/- 3% accuracy validated across all skin tones matters when every SpO2 percentage point counts
Your pediatrician recommends vital monitoring — For infants with breathing concerns, heart conditions, or other health issues, medical-grade validation is worth the premium
You have HSA/FSA funds to spend — Owlet is eligible, effectively reducing your out-of-pocket cost and making the premium more justifiable
You prioritize FDA regulatory oversight — If having an FDA-cleared device provides meaningful peace of mind, that value is real even if subjective

Frequently Asked Questions

Parent checking baby monitor while baby sleeps peacefully in nursery

Are baby monitor smart socks safe for babies?

Yes, both Owlet and Eufy smart socks are designed for infant safety. The American Academy of Pediatrics notes these consumer devices use "relatively conservative thresholds" and are safe for healthy infants 0-18 months (Contemporary Pediatrics). However, they should not replace medical devices for infants with diagnosed conditions—consult your pediatrician for high-risk situations.

Do I need a subscription for either monitor?

Eufy requires no subscription, ever—all features are included with purchase. Owlet's core features (live vitals, video streaming, sleep tracking) work without subscription, but extended video clip storage (beyond 48 hours) requires Owlet360. Neither locks essential monitoring features behind a paywall.

Which has better night vision?

Both monitors offer effective night vision, but Eufy's 2K resolution advantage carries over to low-light situations. Users report Eufy's video is "sharp, even in night mode" while Owlet's 1080p provides "better-than-average video images" with auto-adjusting night vision (Reviewed.com). For seeing your baby's chest rise and fall in the dark, Eufy's higher resolution helps.

Can I use these monitors while traveling?

Eufy works anywhere with its included parent unit (no WiFi required for basic monitoring). Owlet requires WiFi and cannot connect to open networks like hotel WiFi for security reasons—a significant limitation for traveling families. If travel monitoring matters, Eufy is the clear choice.
