Ozlo Sleepbuds 2 are among the best dedicated sleep earbuds available, designed by former Bose engineers to be comfortable on a pillow and to mask disruptive noise all night. Up to 14 hours of battery and the ability to stream your own audio are big upgrades over older sleep buds. At $279 they are a real investment, so use the 30-day return window to check the fit.

When Bose discontinued its Sleepbuds, it left many light sleepers without their favorite tool. Ozlo was founded by former Bose employees who licensed and acquired related sleep technology from Bose and set out to build a better version. The result is Ozlo Sleepbuds, now in their second generation.
These are not regular earbuds. They are small, soft and designed to sit flush in the ear so you can sleep on your side, and they focus on masking noise rather than playing loud music. We looked at what the Sleepbuds 2 do well and where they fall short.
Who is behind Ozlo
Ozlo Sleep is a Boston-based company co-founded by three former Bose employees. Its CEO, N.B. Patil, has more than 25 years in consumer electronics. The company emerged in 2023 with a $10 million Series A round and positions itself as a sleep company rather than an audio brand, using overnight data to personalize its digital sleep tools.
How Sleepbuds 2 handle noise
Many people assume active noise cancellation (ANC) is the answer to a noisy bedroom. Ozlo takes a different approach. A passive seal blocks some sound physically, and soft, consistent audio masks what gets through, which works well for unpredictable noises like snoring, traffic and slamming doors. Ozlo argues that ANC is better suited to steady, low-frequency sounds such as engines and fans.
You can use Ozlo's built-in sleep sounds or stream your own audio, from podcasts to rain recordings. A dedicated button lets you control playback without picking up your phone, and a private alarm wakes you without disturbing a partner.

Battery, tracking and price
Ozlo rates the Sleepbuds 2 for up to 14 hours of continuous use on a single charge, measured with streaming audio and sleep sounds at 50% volume. That comfortably covers a long night. The smart charging case uses five dot-lights on the front to show battery and update status, plus light bars inside the lid for each bud.
The buds include sensors and pair with the Ozlo app, which offers sleep stage breakdowns, sleep pattern insights and tracking of bedroom noise, light and temperature. The app also includes guided meditations, breathing exercises and bedtime reminders.
Price and protection
Sleepbuds 2 cost $279 as a one-time purchase, with no required subscription. Optional Ozlo Care protection is offered at checkout. Shipping is free, the standard warranty is one year, and Ozlo offers a 30-day money-back guarantee. Promotions have occasionally bundled extras such as a year of a meditation app subscription.
Sleep earbuds vs other noise fixes
Before spending $279, it helps to compare the options for a noisy bedroom.
- Foam or silicone earplugs: cheap and effective for many people, but they block sound rather than masking it, can feel uncomfortable over time and do not let you hear an alarm or play audio.
- Bedside sound machines: nothing in your ears and easy to share, but they mask noise for the whole room and may not cover a snoring partner lying next to you.
- Regular wireless earbuds: often too bulky to sleep on, with batteries that may not last the night.
- Dedicated sleep earbuds: slim enough for side sleeping, designed for all-night battery and built around masking, with private alarms so you do not wake a partner.
Sleepbuds 2 make the most sense when cheaper earplugs have not worked, or when you want to listen to something as you drift off without disturbing anyone else. If you mainly struggle with occasional noise, start with earplugs and see whether that is enough.
Getting the fit right
Comfort makes or breaks sleep earbuds. Try each tip size during the first few nights and choose the one that seals without pressure. Insert the buds a few minutes before lying down so they settle, and start with a lower masking volume than you think you need. If you wake with sore ears after a week of trying different sizes, use the return window.
Clean the tips regularly and let the buds charge in the case during the day, since nightly use means they need a top-up most days.
Who should buy Sleepbuds 2
They are an excellent fit for people who share a bed or wall with a snorer, live on a noisy street, work night shifts or travel often. Former Bose Sleepbuds owners will find them a natural upgrade.
They are also useful for couples on different schedules. Because the alarm plays privately in your ears, an early riser can wake without disturbing a partner, and a night owl can listen to a podcast without keeping anyone else awake. Parents of young children should think carefully, though: masking audio is designed to cover disruptive sounds, so make sure you can still hear a baby monitor or alarm if you need to.
If you mostly need darkness rather than quiet, a blackout mask from Manta Sleep is cheaper, and Manta's SOUND mask combines the two. If you prefer nothing in your ears, a bedside sound machine such as Hatch Restore 3 or the Loftie Clock is the gentler alternative.
Our verdict
Ozlo has taken the best idea from the original Bose Sleepbuds and improved it with longer battery life, streaming and sleep insights. The price is high, but for light sleepers in noisy homes, better nights can be worth it. Buy direct to get the 30-day guarantee and warranty.
