Noise Control

Soundcore Sleep A30

Is set apart by its 3-stage snore-masking system. The charging case actually listens for snoring in real time, then sends masking sounds to the earbuds to counter it.

In addition, Anker includes AI-powered “brainwave audio” using binaural beats and soundscapes designed to help you relax.

Overall, there’s a lot of innovation packed into the Soundcore Sleep A30: smart ANC, adaptive snore-masking, immersive sleep audio, and available memory foam eartips for optimum noise-blocking performance.

Ozlo Sleepbuds

Takes a more traditional approach to noise control, relying mostly on passive, rather than active noise cancellation.

Instead of actively cancelling noise, the earbuds physically block disturbances and play soothing soundscapes.

Environmental and Bio-metric Sensing technology currently on the Ozlo Sleepbuds are geared more toward sleep tracking than real-time noise control.

At the day’s end, the Ozlo Sleepbuds stick to a conventional formula rather than pushing boundaries with more advanced noise cancellation technology.

Noise Control Advantage — Soundcore Sleep A30

Soundcore Sleep’s ANC is designed to be adaptive, effectively detecting and cancelling out noise at varying frequencies. Ozlo Sleepbuds’ noise-blocking being fixed, will only hold up in low to moderate noise settings.

Battery Life

Soundcore Sleep A30

Delivers a strong battery performance overall, offering up to five nights of use on a single charge.

Playing only sleep sounds (Local Mode), you can expect about nine hours of playback with ANC turned on.

Since noise control is active and Bluetooth streaming is available, nightly battery life varies extensively; ranging from 6.5 hours to as much as 14 hours.

All in all, a full night’s sleep is achievable on the Soundcore Sleep A30 — for 5 straight nights without recharging the case. And external battery indicators are a plus for charge monitoring.

Ozlo Sleepbuds

Offers great performance (roughly 9.5 to 10 hours) from the earbuds on a nightly basis. But falls short of projections for the case.

The lack of external battery indicators on the case also makes charge monitoring inconvenient.

Overall, future-proofing the earbuds for sleep tracking significantly reduces the battery life and dashes any chances of surpassing 3 nights from typical use.

Battery Life Advantage — Soundcore Sleep A30

Soundcore Sleep’s battery life only falls short with one group of users (Bluetooth + ANC turned on—all night). To be fair, most sleep buds in the market will likely perform similarly.

That flaw aside, they offer all other users a work-week’s worth of nightly play time on a single charge, plus case charge monitoring at a glance.

Ozlo Sleepbuds on the other hand is not as versatile. And after the first, they can only offer two additional nights from mixed use. No charge monitoring by glancing at the case.

Comfort and Fitment

Soundcore Sleep A30

Offers a generally comfortable and highly customizable fit. The new thicker (but softer) silicone may need some acclimatisation.

The slim profile aids side-sleeper comfort and a wide range of fitment options (ear tips and wings) means that users can fine-tune fitment to their preference.

There’s multiple sizes of silicone eartips and ear wings to pick from, with two color options available.

Ozlo Sleepbuds

Are one of the most compact sleep buds on the market. Paired with a simple silicone ear-wing-tip design, they have a straightforward, yet effective approach to comfort.

This is especially good for folks that prefer a more user-friendly or straightforward fitting process.

One downside is the lack of color options, as the earbuds are only available in white silicone.

Comfort and Fitment Advantage — Ozlo Sleepbuds

Let me explain.

Side sleeper comfort is achieved mainly by eliminating pressure to the ear.

Soundcore’s effort to provide a wide range of fitment accessories is commendable (same sizing options are available on both).

But in real-world use, the more compact size and simple accessories of the Ozlo Sleepbuds translate into less pressure for heavy side sleepers.

Overall, I found myself adjusting the Soundcore Sleep A30 (for seal and comfort) more than I did the Ozlo Sleepbuds.

Smart Features

Soundcore Sleep A30

Supports Find Device and Bluetooth calls (both practical features that the Ozlo Sleepbuds doesn’t).

In addition, Soundcore’s sleep library is significantly more advanced. Including AI Brainwave Audio and binaural beats — which aim to push beyond basic results into realms of quicker relaxation and more restful sleep.

Ozlo Sleepbuds

Stands out with their two-way content auto-switching (Soundcore Sleep A30 has a one-way setup).

Their sound library might be basic but they compensate by providing larger memory on the earbuds—each capable of storing the entire sound library.

Smart Features Advantage — Soundcore Sleep A30

Based on the tech specs, the Soundcore Sleep A30 can be considered the smarter device overall.

With the ability to switch sounds mid-play (with the app closed)—No need to download and replace the current track, the Ozlo Sleepbuds comes in a really close second.

For me, not being able to take a call (a call I want to take) or find missing earbuds is pretty hard to ignore.

Pricing

This one’s pretty straightforward. MSRP for the Soundcore Sleep A30 is $329.99 CAD. That’s $69.01 lower than the Ozlo Sleepbuds ($399 CAD).

At the time of this post, discount price for the Soundcore Sleep A30 is $279.99. That’s $33.01 lower than the Ozlo Sleepbuds discount price ($313 CAD).

Pricing Advantage — Soundcore Sleep A30

Discount prices help the Ozlo Sleepbuds to close the cost gap between the devices.

All in all, every dollar counts and Soundcore Sleep A30 buyers may not be laughing to the bank, but they will have change to spare.

Verdict

Before we tally the numbers, I think the additional features are worth mentioning.

Bluetooth Streaming is supported on both devices.

Sleep Tracking is only available on the Soundcore Sleep A30. Even though the “monitoring” part might already be underway, tracking your sleep is not yet available on the Ozlo Sleepbuds.

Alright then, let’s check out the results.
