Meet the NEW Ozlo Sleepbuds 2

Ozlo Sleepbuds are the most raved-about product I've ever shared. They've just released the new Version 2, and the upgrades are impressive. Here's what's new.

This issue is sponsored by the NEW Ozlo Sleepbuds 2, which I never shut up about (for good reason). Get them at an even lower (!) price point, plus $20 off with the code MELISSAURBAN.

I first tried Ozlo Sleepbuds over a year ago, after discovering them through an Instagram ad. I had tried everything to sleep through my husband’s (and dog’s) snoring, and nothing worked. Then I found Ozlo Sleepbuds:

It is not an exaggeration to say the heavens parted, the angels sang, I liked my husband again, and I was sleeping better than ever. Today, Ozlo released their new Sleepbuds 2, and they are a huge level-up. Here’s an Ozlo 101, what’s new and improved in the Sleepbuds 2, and an extensive FAQ.

What are Ozlo Sleepbuds?

Ozlo Sleepbuds are tiny earbuds specifically designed for sleep. They’re noise-masking, lie flat in your ear, are comfortable all night (even as a side-sleeper), and beam a soothing variety of noises into your ears all night long. They have built-in sounds (like white noise, nature sounds, and soothing melodics), but you can also stream your own podcasts, audiobooks, meditations, or music. They’ll even automatically detect your sleep and switch from streaming into your selected sleep sound!

What is “noise-masking?” Active Noise Cancellation (ANC) is often found in traditional earbuds. ANC tries to physically eliminate external noise, but they tend to be bulky and create in-ear pressure, which many find uncomfortable overnight. Noise Masking (as found in Ozlo Sleepbuds 2) works by giving the brain a steady sound to focus on (like white noise or the sound of rainfall), so it ignores unpredictable interruptions. Ozlo Sleepbuds 2 are tiny (with less than half the in-ear profile of Airpods), light (less than a third of the weight of Airpods), and comfortable, even overnight.

Ozlo Sleepbuds effectively mask snoring—yes, even from the chainsaw sleeping right next to you. They also mask noises from loud upstairs neighbors, street noise, noisy hotel environments, my neighbor’s 4th of July fireworks, and the church bells clanging every hour all night long in Switzerland. They work far better than headphones or earplugs, are more comfortable than any earbud, and have an impressive battery life, so you can fall asleep faster and—more important—stay asleep longer.

I’ve been wearing my original Ozlo Sleepbuds for over a year, and they’ve worked beautifully. However, they’ve always had a few quirks. I lived with them because the product was a can’t-sleep-without… but I’m thrilled to see that Ozlo resolved all of those quirks, and added some new features that I didn’t even know I needed.

What’s new with the Ozlo Sleepbuds 2

The short answer is, a lot. This isn’t just a color change and a few new sounds—they’ve completely redesigned these from the ground up. Here are the highlights:

🔋 Increased battery life: 10 hours → up to 14 hours

My original Ozlos play white noise for about 10 hours. The Ozlo Sleepbuds 2 claim to have a battery life of up to 14 hours. However, having worn them for the last month… mine go way longer than that. Using the in-bud Sleep Sounds (no Bluetooth), I sleep for 8 hours and wake with 50% battery left in each bud. This is an insane improvement. (Note, the Ozlo Sleepbuds 2 battery life varies based on how you use them; Bluetooth streaming uses more battery.)

⚡ Improved connectivity: Way faster

The original Ozlo buds needed 6-8 seconds to connect before you can put them in your ear. (And if I pulled them out of the case too early, I’d have to return them to the case, close the lid, open the lid, and start the connection process over. Annoying when you’re about to fall asleep.) Ozlo Sleepbuds 2 connect automatically as soon as you open the lid. It’s a small change, but makes a huge difference in the overall experience.

🔌 In-case charging: No more dead buds

This was the quirk that actually annoyed me with the original Ozlos. When you replaced the buds in the case, you’d have to wiggle them around until they connected just right. There was too much room and too weak a magnetic hold to guarantee correct placement. And if you didn’t get them just right, you’d put them in at night to discover they were dead, which would either enrage me or make me want to cry, because my husband was already snoring and I was so tired. But the Ozlo Sleepbuds 2 snap into the newly-designed case perfectly. There is a strong magnetic catch and zero wiggle room now—you cannot get the placement wrong. This is a huge and impactful improvement.

Also, the original Ozlo buds would sometimes draw power from the case while inside, even when the case was closed. This sucked, because you’d think your case had enough charge for one more night, only to find it was dead as a doornail. The newly-designed buds no longer do this, so the buds and your case remain charged, and you’ll get a longer battery life out of the case itself.

▶• Improved listening: Volume and Sound Modes

I use the built-in white noise sounds as I sleep, but if you use your Sleepbuds to stream content, this is going to be a bangin’ improvement. The sound quality is clearer at low volumes, and you’ve got a wider range of volume controls.

• For streaming content, Ozlo Sleepbuds 2 reach up to about 88 dBA in Balanced and Office modes, and 90 dBA in Spoken Word and Airplane modes.

• Built-in sleep sounds are intentionally capped at 85 dBA in accordance with NIOSH hearing safety guidelines, since they're designed to play throughout the night.

• Note, Ozlo does not recommend listening at max volume. In general, find the lowest volume that still effectively masks the noise in your surroundings.

There are also new Sound Modes for streaming, so you can customize and improve your listening experience:

• Balanced: Best for music and everyday listening.

• Spoken Word: Optimized for audiobooks and podcasts, making voices sound clearer and easier to understand.

• Airplane: Designed for louder environments (like airplane cabins), helping speech and audio remain clear over constant background noise.

• Focus: Similar to Balanced, but with some of the higher frequencies softened. This reduces sharper sounds (like cymbals or harsh “S” sounds) so music stays more in the background, making it ideal for working or concentrating.

Note, these Sound Modes will not affect built-in sleep sounds; they only apply to streaming content.

🥱 Functionality: New Smart Case button

The new Ozlo Sleepbuds 2 feature a small, easily-accessible button inside the Smart Case. Pressing this button can pause and play your earbuds, snooze your in-ear alarm, quickly pair the buds to your device via Bluetooth, or reboot your buds. Previously, if you wanted to pause the sound, you had to take the buds out of your ears or turn on the app—inconvenient in the middle of the night. With the new Smart Button, none of these actions require your phone! (See the next bullet for one exception.)

💤 Sleep Modes: Even more versatility

You now have even more control over how you listen at bedtime. There are five Sleep Modes:

• Simple: Sleep sounds play as soon as you remove the buds from the case, and all Bluetooth connectivity shuts off after 10 minutes. (Note, because there is no overnight Bluetooth connection, you won’t be able to use the Smart Case button to pause your content or snooze your alarm in Simple mode.)

• Auto: Stream your own content, and when the content (podcast, meditation, etc.) ends, your Sleep Sound will automatically start playing.

• Sensing: Stream your own content, and when the buds sense you’ve fallen asleep, it will automatically transition to your Sleep Sound.

• Time delay: Stream your own content, and after a specified period of time (anywhere from 1 minute to 2 hours), your Sleep Sound will start playing.

• Manual: Stream your own sounds, and use the Smart Case button or the app to start your Sleep Sound.

Ozlo also offers an easy quiz in the app (under “Sleep Mode”) to help you find the setting that works best for you.

👂 Ear Tips: The Extra-Small is all new

A lot of you have told me, “My ears are tiny, and most in-ear buds don’t fit.” While Ozlo’s XS ear tips already worked for many of you, the redesign should work even better. You’ll now experience the same cushioning found in the larger sizes, while still keeping it suitable and comfortable for the smallest ears.

📲 The Ozlo app: Much more user-friendly

The Ozlo app also got a huge refresh, and it’s far easier to use. There are more customizable settings, the home screen walks you through what’s new, and the sounds are now organized into easy-to-understand categories. You can also preview all of the sounds on your phone, which is a feature I’d been asking for. (Originally, you had to have the buds in your ears to preview different sounds, which wasn’t convenient.)

💵 The price point: A welcome surprise!

The original Ozlo Sleepbuds retailed in the U.S. at $349. The base price of the Ozlo Sleepbuds 2 in the U.S. is $279! When does a tech company offer you more, better features and a lower price point? Plus, if you purchase Ozlo Sleepbuds 2 at launch, you’ll get a FREE Travel Case and a FREE Ozlo Sleep Mask with your order (a $58 value). Just another reason why Ozlo has my loyalty for life.

My observations after using Ozlo Sleepbuds 2 for a month

Here’s what I think of the newly-designed Ozlo Sleepbuds 2. Spoiler: I love them even more, and I already loved them to infinity.

• They feel smaller in my ears. Ozlo swears the new buds are the same general size as the old, but though the originals were comfortable, the Ozlo 2 fit better in my ears. The core of the bud sits more flush, and I cannot feel them at all when I side-sleep. I noticed it on the very first night, and it’s surprisingly significant.

• I love the new sleep sound categories. The newly-designed app breaks down their 50+ built-in sleep sounds into three categories:

  • Masking sounds remain steady throughout the night, like Jade Static (the mid-frequency sound that I use) or Crimson Cloak (offering a low, warm tone).

  • Soundscape sounds have natural variation, like Distant Thunder or Beach Walk, but remain steady enough to be relaxing, never jarring.

  • Nocturnes sounds are new! These are ambient melodies and harmonies that are soft and immersive, designed to feel peaceful and relaxing. I love Solena for the orchestral feel, and Velora for the ethereal flow.

• The overall experience is smoother. The connection is fast, the sound selection is bigger, the battery life is elite, I never have to worry about them not charging properly, and they fit more comfortably.

In summary, this isn’t a tech company changing a few small features that nobody asked for and calling it a “Version 2.” This is an entirely redesigned, far-improved product clearly based on the feedback of their community.

Ozlo Sleepbuds 2: Tiny, comfortable, effective, and at an all-new price point

An Ozlo Sleepbuds 2 FAQ

This is an all-new FAQ, which I’ll continue to keep updates as you have questions. (You can leave them in comments.) I want this article to be the definitive guide to the new Ozlo Sleepbuds 2.

What can you listen to on Ozlo Sleepbuds 2? You can choose from a selection of neuroscience-backed relaxing sounds pre-loaded in the Sleepbuds themselves. Or, via low-energy Bluetooth, you can stream whatever you choose—music from Spotify, audiobooks from Audible, meditations from Calm, or podcasts from your favorite player. You can even mix and match by streaming your own content, then transitioning automatically into a built-in Sleep Sound. Ozlo Sleepbuds 2 also offer a gentle built-in alarm of your choosing, so you wake easily without disturbing your partner. (Oh, the irony.)

How do they fit? They’re designed to gently sit inside the ear canal. There are four different size ear tips (the circular piece that sits in your ear canal) from XS to L, and have a matching silicone “wing” that hooks in behind your ear ridge. They stay put all night with exceptional comfort, even as a side sleeper; I’ve never had one fall out.

How far can you travel away from the case? Ozlo states you can travel up to 10 feet from the case with the sleepbuds in your ears. I will note, however, that I’ve gone much farther—like from my bedroom to the kitchen to let the dogs out in the middle of the night. I can’t say for sure that your connectivity will be longer than 10 feet, but the new Ozlo Sleepbuds 2 does feature much-improved connection compared to the originals.

How do you feel about the Bluetooth/EMF overnight? Bluetooth is necessary to pair the Sleepbuds with your device, but uses BLE (Bluetooth Low Energy). This form lowers your EMF exposure compared to other devices like a phone or laptop. Once paired, Bluetooth is only used if you want to stream audio. If you use the built-in sleep sounds (as I do), the software cuts all communication from the buds to the case after 10 minutes, so there is no connectivity to anything as you sleep, and you can use your Sleepbuds without ever touching your phone.

Can you damage your hearing leaving them in overnight? Ozlo Sleepbuds 2 were thoughtfully designed for comfort and safety. Built-in sleep sounds are intentionally capped at 85 decibels (dBA) in accordance with NIOSH hearing safety guidelines, since they’re designed to play throughout the night. However, Ozlo recommends not listening at full volume. Ideally, you’ll find the lowest volume that still effectively blocks out ambient noise. Mine are set to 60%, which is 51 dBA—about the same level as gentle rainfall or a quiet fan, and well below occupational hearing safety limits.

Will they block out too much noise? This is entirely based on your settings. At my current volume, I don’t wake up when my husband or dogs snore, but if one of them barks (the dog, not the husband) I do hear that. Same with my kid coming into the room because I TOLD YOU IT WAS TOO SCARY TO WATCH, or our home alarm going off because my dad forgot and opened a window. The volume and sound controls in the Ozlo Sleepbuds 2 are more versatile, so you’ll be able to find the settings that works for you.

What’s the battery life? If Bluetooth is off, I’m seeing 14+ hours per charge. (When I wake after 8 hours of sleep, my buds still have 50% charge!) If Bluetooth is on, your battery will drain faster—how much depends on how long you stream, and your individual settings. A full charge takes about 2.5 hours, but you can get them to a half-charge (which should accommodate a full night’s sleep using the built-in Sleep Sounds) in just 1.5 hours.

What’s the maintenance? In a word, minimal. The case is a Sleepbud charger, and can fully charge my buds 3-4 times. You can recharge the case using a standard USB-C cord. Cleaning the ear tips is easy: Detach them from the buds and wash gently with warm water and mild soap, then let them air-dry before reattaching them to the buds. (For daily cleaning, you can wipe them gently with a soft dry cloth.)

Ozlo Sleepbuds 2 change the sleep game

I first posted a glowing review of Ozlo Sleepbuds in July 2025. I had been using them for just over a month, and was so impressed I had to share them. At that point, I had zero affiliation with the company. I bought the buds with my own money, followed the user guide like any other customer, and used their “help” resources when I had questions.

Two months later, a long-time friend reached out: “I’ve moved on from (old) company to Ozlo Sleepbuds, and I’d love to send you a pair to try.” My reply contained an overabundance of exclamation points: “I am already your biggest brand fan!!! I LOVE OZLO!!! Let’s talk!!!” Since then, Ozlo has become a sponsored partner, and I’ve become a personal investor in the company.

This product, above all others, has also generated the highest number of glowing reviews from my community:

• “I’m so grateful for your Ozlo recommendation, we got to sleep together the WHOLE night.” —Cathy

• “I bought these for my daughter. She’s 21, at college, and doesn’t drink, and gets soooo annoyed not being able to sleep with all the noise. Thank you!” —Kristen

• “Ozlos are worth every penny if I don’t want to feel ragey and stabby every night sleeping next to my husband.” —Andrea

• “OMG! I cannot believe how glorious my first night of Ozlo sleep was! Did not wake up from my husband’s snoring even once!” —Brianna

If you’re ready to sleep better than ever (especially in your own bed) use the code MELISSAURBAN to save $20 on the new Ozlo Sleepbuds 2. Also, tell your couple’s therapist I’M SORRY for the decreased billings now that your snoring spouse is no longer making you want to plan your own disappearance.
