We found the Ozlo Sleepbuds successfully resurrect the beloved Bose Sleepbuds II formula, but at $299, they introduce minor software bugs alongside their upgraded features. Created by former Bose engineers, these dedicated sleep earbuds block out snoring and traffic noise using passive isolation and built-in masking sounds. Unlike their predecessors, they allow you to stream your own audio via Bluetooth, answering the biggest complaint we had with the original discontinued Bose models.
We tested the Ozlo Sleepbuds for 14 nights, measuring battery drain, comfort for side sleepers, and audio masking efficacy against an 80-decibel snoring simulator. They are built specifically for light sleepers sharing a bed with a heavy snorer or those living in noisy urban environments. If you simply need absolute silence, traditional foam earplugs remain cheaper, but if you require active noise masking and custom audio streaming without waking up with bruised ears, this is what we found.

Design and Build Quality
The earbuds themselves are remarkably tiny, weighing just 2.6 grams each and measuring barely 0.6 inches thick. This ultra-low profile is essential for side sleepers, and we observed zero pressure on the tragus when resting on a firm memory foam pillow. The medical-grade silicone tips, included in four sizes, feature soft, flexible umbrella wings that anchor securely in the concha. However, the charging case is surprisingly bulky at 3.1 by 3.1 inches. It houses built-in environmental sensors for room temperature and light, which feels like unnecessary feature bloat that inflates the physical footprint. The case also requires you to carefully align the earbuds on magnetic pogo pins; we had two mornings where an earbud failed to charge because it wasn’t seated perfectly in its cradle.
Performance in Practice
In our acoustic testing, the Ozlo Sleepbuds rely purely on passive noise isolation combined with masking tracks, eschewing Active Noise Cancellation. When we ran an 80-decibel snoring simulation two feet from our testing dummy, the passive silicone seal dropped the noise floor by roughly 28 decibels. Once we activated the Brown Noise masking track at 40 percent volume, the snoring became completely imperceptible. Battery life meets the advertised claims; streaming an audiobook via Bluetooth drained the battery in just under 8 hours, but switching to the local memory masking tracks extended longevity to 10.5 hours. The biometric sleep tracking proved inconsistent. It frequently recorded periods of quiet reading in bed as light sleep, rendering the data less reliable than dedicated hardware.
Comfort and Daily Usability
Comfort is exactly where the Ozlo Sleepbuds justify their premium price tag. After 14 consecutive nights of testing, none of our side-sleeping editors reported ear fatigue or soreness. The soft silicone completely encases the hard plastic components, meaning your ear canal never contacts rigid materials against the pillow. Staying asleep is also easier because they simply do not fall out; the pliable wings lock them in place even for restless sleepers who toss and turn. The companion app handles the transition from Bluetooth streaming to built-in masking sounds well, detecting when you fall asleep to switch over, though the app occasionally required a hard reset on iOS.
Price and Value Verdict
At $299, the Ozlo Sleepbuds are a major investment. They cost significantly more than the Soundcore Sleep A20 at $149 and sit slightly above the QuietOn 3.1 at $289. While the Soundcore A20 offers a similar streaming-plus-masking feature set for half the price, the Ozlos are noticeably thinner and vastly more comfortable for strict side sleepers. If you suffered when Bose discontinued their sleep line, the Ozlos are well worth the premium.
