Overview

Ozlo Sleepbuds 2 are noise-masking sleep earbuds built for side sleepers, people who share a bed with a partner who snores, and anyone using a CPAP machine overnight. Each earbud weighs 1.6 g and sits just 11 mm tall without the tip, so the low-profile shape stays comfortable when your ear presses into the pillow.

Instead of active noise cancellation, Sleepbuds 2 use a silicone seal for passive noise reduction plus masking audio that covers residual sound like snoring, traffic, or city noise. Once the built-in accelerometer detects you've fallen asleep, the buds switch into full masking mode automatically.

A single charge plays for up to 14 hours (Ozlo's own testing at 50% volume; actual time varies with use), and the Smart Case holds 2 to 3 extra charges over USB-C. The free Ozlo Sleep App comes with no monthly fee and gives access to 50+ sleep sounds, sleep tracking, and four sleep modes. See the rest of the lineup in our Ozlo collection.

Important Tips

  • Find your seal first: Try all four tip sizes (XS, S, M, L) until one creates a snug, comfortable seal; a good seal is what makes the passive noise reduction work.
  • Charge the Smart Case before bed: Keep the case topped off so it's ready with 2 to 3 extra charges when you need them.
  • Set up phone-free playback: In the app, configure your buds to start a Sleep Sound automatically when you take them out of the case, so you don't need your phone at bedtime.
  • Turn on Sleep Shield: Enable Sleep Shield before you go to sleep so incoming calls, alerts, and notifications stay silent until morning.
  • Use the private alarm to protect your partner's sleep: Set your alarm in the buds so it wakes only you, even with Bluetooth off.
  • Pack light for travel: Bring the Smart Case and USB-C cable; the case both charges and stores the buds on the go.
  • Wipe tips after workouts: The IPX4 rating covers sweat and light rain, so wipe the tips dry after exercise before storing them in the case.

Product Features

Comfortable Enough to Sleep On Your Side
Each Ozlo Sleepbud weighs 1.6 g and stands just 11 mm tall without the tip, so the low-profile shape stays comfortable when your ear presses into the pillow. Four silicone tip sizes (XS, S, M, L) let you dial in a secure seal for your ear.

Noise Masking, Not Active Noise Cancellation
Sleepbuds 2 don't use ANC. The silicone tip creates a passive seal that blocks sound on its own, and masking audio covers whatever gets through, like snoring, traffic, or city sound. Ozlo's own testing found masking works better than ANC for falling and staying asleep.

Up to 14 Hours of Playback Per Charge
A full charge plays for up to 14 hours in Ozlo's testing at 50% volume; actual time depends on use. The Smart Case adds 2 to 3 more charges on the go and recharges itself over USB-C.

50+ Sleep Sounds, No Phone Required

Sleepbuds 2 store more than 50 sleep sounds and soundscapes directly on the buds, so they play without a phone nearby. You can set them to start your Sleep Sound automatically the moment you pull them out of the Smart Case.

Stream Anything Over Bluetooth, Free App Included

Beyond the built-in sleep sounds, the buds pair over Bluetooth 5.3 (A2DP and LE Audio) to stream music, podcasts, or audiobooks from Spotify, Calm, Audible, YouTube, or any Bluetooth source. The Ozlo Sleep App is free, with no monthly fee or subscription, and runs on iOS 17+ or Android 12+.

Switches to Masking Automatically Once You're Asleep

An accelerometer in each bud detects when you've fallen asleep and switches the audio into full masking mode on its own, no button press needed.

A Private Alarm Only You Can Hear

The in-ear alarm plays through the buds themselves, so it wakes you without waking a partner. It works without a phone nearby, even with Bluetooth turned off, and you can snooze it with the Smart Case button.

Smart Case With Room Sensors and Sleep Tracking

The Smart Case has a button for play, pause, and snooze, plus sensors that read the noise, light, and temperature in your room. Paired with the accelerometer in the buds, this feeds Sleep Patterns in the app: sleep duration, time in bed, consistency, efficiency, and disruptions from your environment.

Four Sleep Modes Plus a Sleep Shield

Choose from four Sleep Modes (Simple, Auto, Sensing, and Time Delay), set a Sleep Timer, and turn on Sleep Shield to block incoming calls, alerts, and notifications overnight. Four audio profiles (Balanced, Spoken Word, Focus, and Airplane) adjust the sound to what you're listening to.

What's Included in the Box

Every order includes the Ozlo Sleepbuds 2, the Smart Case for charging and storage, four sizes of soft silicone tips (XS, S, M, L), and a USB-C charging cable.

Sweat and Splash Resistant, With a 1-Year Warranty

Sleepbuds 2 carry an IPX4 rating, so dust, sweat, and light rain won't damage them. Ozlo backs the buds with a 1-year US manufacturer warranty.

FAQs

Is there a monthly fee for Ozlo Sleepbuds 2?

No. The Ozlo Sleep App is free, with no monthly fee or subscription. You just need iOS 17+ or Android 12+ to use it.

Is Ozlo the same as Bose?

No, Ozlo is a separate company, but it was founded by former Bose engineers and builds on the legacy of the original Bose Sleepbuds.

Do Ozlo Sleepbuds 2 have noise cancelling (ANC)?

No. Sleepbuds 2 use noise masking instead of ANC. The silicone tip creates a passive seal that blocks sound on its own, and masking audio covers whatever noise gets through. Ozlo's own testing found masking works better than ANC for sleep.

Can I take phone calls with Ozlo Sleepbuds 2?

No. There's no microphone in the buds, so they're built for sleep audio and streaming, not calls.

Will the battery last all night?

A full charge plays for up to 14 hours in Ozlo's testing at 50% volume, which covers a typical night. The Smart Case also holds 2 to 3 extra charges if you need them.

Are Ozlo Sleepbuds 2 comfortable for side sleepers?

Each earbud weighs 1.6 g and sits just 11 mm tall without the tip, with a low-profile shape designed to stay comfortable when your ear presses into the pillow. Four tip sizes (XS, S, M, L) help you find a secure fit.

What's new in Sleepbuds 2 versus the original Ozlo Sleepbuds?

Battery life goes up to 14 hours per charge, compared with up to 10 hours on the original Sleepbuds, and Sleepbuds 2 add a Smart Case with a button for play, pause, and snooze plus sensors that read room noise, light, and temperature.

How does the automatic switch to masking work?

An accelerometer in each bud detects when you've fallen asleep and switches the audio into full masking mode automatically, without you pressing anything.

What's included in the box?

You get the Ozlo Sleepbuds 2, the Smart Case for charging and storage, four sizes of silicone tips (XS, S, M, L), and a USB-C charging cable.

Can I use the alarm without waking my partner?

Yes. The in-ear alarm plays only through your buds, so it wakes you without disturbing anyone next to you. It works even without a phone nearby or with Bluetooth off, and you can snooze it from the Smart Case button.

Do Ozlo Sleepbuds 2 work without a phone?

Yes. More than 50 sleep sounds are stored directly on the buds, so you can play them, use the private alarm, and snooze from the Smart Case button without a phone nearby.
