Introduction
In case you are in search of earbuds specially created to be worn during sleep, there is the Ozlo Sleepbuds that you may have noticed. These sleep-oriented earphones are developed by former Bose employees and they have some of the features such as noise masking, streaming, tight fit, and long battery life. This Ozlo Sleepbuds Review will discuss their real-life performances in sleep scenarios: what they are doing good, what is not doing well, and their worth in terms of the investment.
Key Features
Earconscreens and Sound Masking Streaming
- Ozlo has an in-built library of sleep-optimized sounds (white noise, ocean tide, rain, etc.).
- They are also able to stream personal audio (music, podcasts) and then automatically switch to sleep sounds when it detects sleep, unlike some older models of sleep earbuds.
Battery Life & Case
- Its earbuds have a life span of approximately 10 hours of use.
- It has extra time on the charging case, and with several nights of use, it may be recharged.
Controls & Smart Features
- Sound choice, volume, sleep/streaming options and timers are managed by a companion application.
- It has a personal alarm option thus you can wake up without disturbing another person.
- Ozlo is advertised as upgradable in the future: sleep/environmental (light, noise, etc.). As of this review those are proposed but not operational.
Price & Subscription
- MSRP around $299.
- They have also a subscription offer (e.g. Ozlo Flex) that charges the payment and adds more benefits.
Comfort & Fit
- The structure is non-rigid, lightweight with silicone tips and wings to aid the fitting and stability.
- Ear tips are available in various sizes in order to fit the ear shape.
- Among the most comfortable sleepbuds that have been tested by side sleepers are the buds; most of the users claim that they stay in, do not cause any pain or are hardly felt when in the sleep.
- Cons: Some users continue to complain of the pillow-side discomfort based on ear/pillow combination and some will complain that the bud on the pillow side can be pressed or intrusive.
Acoustics and Noise Cancellation
Masking and Quality of Sleep-Sounds
- Sleep-sound library is of good quality; sounding is relaxing and can effectively cover the usual nighttime sounds (snoring, traffic, ambient noise).
- Weak bass can be felt – when it comes to music, or bass-intensive content, lows are muted. However, in most cases, that absence to their advantage (less intrusive) is much like sleep sounds.
Noise Blocking / Isolation
- It does not have active noise cancellation (ANC). The buds rely on passive isolation (ear tip seal and soft material) and masking sounds.
- They are fairly good at preventing higher frequencies, not so much of very low frequency rumble or extreme low bass.
- There were also cases when some users heard crackling/static noises during quiet moments or when nothing has been sent out. It can be noticeable.
Streaming vs Built-in Sounds
- Self audio work streaming is possible, but the volume control of the default built-in sleep sounds is via Ozlo app, not the phone volume.
- The switching of streaming to sleep sound (where the sleep is detected) is useful but inconsistent.
What Doesn’t Work Perfectly
- Charging Problems: Reports of unreliable charging (buds not always fitting into the charger correctly), connectivity lag / long connectivity time than anticipated.
- High Price: This product is priced high at about 300 and to some of the potential customers, it is not worth the money since alternatives can be found at lower prices.
- None Active Noise Cancellation: To people with high expectations of complete suppression of loud and low-frequency noise, the absence of ANC can be a killer feature.
- Missing Lack of Sleep Tracking (at least): Despite the promise, as many of the reviewers and users observe, the advanced sleep-or environmental tracking options are not fully available.
- Alarm Feature: The alarm is too sudden in the eyes of some.
Verdict: Who Should Buy Them?
| Works Best For | May Not Be Most Fitting To |
|---|---|
| Lightweight and comfortable sleep buds are needed by side-sleepers. | Users that require high levels of ANC or deep bass to play music. |
| Users who desire to stream their own music and in-built sound to sleep. | Low-end purchasers who may be able to purchase other alternatives at a lower price. |
| People that are irritated with noise (snoring, traffic in the city) but do not have to have total silence. | Users that are conscious of connection problems or minor hardware problems. |
| Any user who likes this type of control of the app, timer, and alarm built into earbuds. | Individuals anticipating a refined product that has all the targeted features functional at once. |
All in all, I think they are very useful in their primary use i.e. in getting sleep in this Ozlo Sleepbuds Review. They do best at comfort and sound masking, at some expense. Assuming that you can tolerate a few of the quirks, they are one of the best at the moment when it comes to sleep earbuds.
Summary (Pros & Cons)
Pros:
- Very cushy, particularly to side sleepers.
- Excellent passive noise isolation + pleasant masking sounds.
- Personal audio streaming capability.
- Long battery life (buds + case).
- Valuable functions through app, sleep timer, alarm.
Cons:
- Price is high.
- None of the active noise cancellations.
- Bass is meager — less admirable in the taste of music.
- Some report connectivity and charging problems.
- Sleep tracking, environmental data features are not quite accessible yet.
Conclusion
The Ozlo Sleepbuds provide much: they are very comfortable, masking sounds are designed, and they have smart features that help people fall asleep, in case you are interested in a dedicated sleep system. Although they have their flaws, especially when it comes to those who anticipate a good bass level, or even ANC, and an overall unbroken experience immediately after purchase, they are a robust competitor in the sleep-earbuds category.
They are worth the price of $299 (or subscription) based on the level of comfort and quality of sleep. These might repay in sleep to many side sleepers who have noise problems.
