What are Ozlo Sleepbuds and what do they do?

Answer

Ozlo Sleepbuds are ultra-small earbuds built specifically for sleep. We help you sleep through unwanted noise by combining a comfortable in-ear seal (passive noise blocking) with Sleep Sounds that mask and replace disruptive bedroom sounds. You can also stream audio over Bluetooth when you want to fall asleep to podcasts, music, or audiobooks.

What to know upfront

  • We use passive noise blocking plus noise masking (not active noise cancellation).
  • You can choose built-in Sleep Sounds or stream audio.
  • You can wake up with a private in-ear alarm without waking your partner.
  • Once you set us up, you can use a phone-free mode for built-in Sleep Sounds.

What’s in the box?

Answer

Inside the box you’ll find:

  • Ozlo Sleepbuds
  • Smart Charging Case
  • 4 pairs of silicone ear tips (sizes 0–3)
  • USB-C charging cable

How the system connects (this helps you understand range and troubleshooting)

  • Sleepbuds connect to the Smart Case using Bluetooth Low Energy.
  • The Smart Case connects to your phone for control and streaming.

What do I need before first use?

Answer

Before your first night, you need:

  • A compatible phone (iOS 17+ or Android 12+)
  • The Ozlo Sleep app installed
  • Bluetooth turned on
  • The Smart Case plugged into power for initial setup and charging

Important charging note

Charge at room temperature. Avoid charging if the earbuds are very cold or very hot.

Step-by-step: first-time setup

Question: How do I set up Ozlo Sleepbuds for the first time?

Answer: Charge first, install the app, pair in the app, then confirm fit and choose your bedtime audio.

Step 1: Charge the Smart Case and Sleepbuds

  1. Plug the Smart Case into power using USB-C.
  2. Put both Sleepbuds into the case.
  3. Close the lid to begin charging.
  4. Let them charge fully before your first full night (a full charge can take up to about 3 hours).

Step 2: Install the Ozlo Sleep app

  1. Download the Ozlo Sleep app from the App Store or Google Play.
  2. Open the app and follow the on-screen setup prompts.

Step 3: Pair your Sleepbuds (in the app)

  1. Turn on Bluetooth on your phone.
  2. Keep your phone, case, and Sleepbuds within 10 feet (3 meters).
  3. Open the case lid (leave the Sleepbuds inside).
  4. In the app, choose Pair New Device (or follow the setup flow).
  5. Wait for the app to confirm you’re connected.

Step 4: Update firmware (recommended)

  1. In the app, install any available firmware updates.
  2. Keep the case plugged in and the lid open during updates.
  3. Keep your phone close to the case until the update finishes.

Step 5: Pick your first-night settings

  1. Choose your preferred Sleep Sound (if you plan to use built-in masking).
  2. Set an alarm (optional).
  3. Confirm your ear tip size and comfort (see the fit section below).

Step-by-step: getting the best fit (comfort + noise blocking)

Question: How do I get the most comfortable fit, especially for side sleeping?

Answer: Use the right tip size, seat the earbud fully, and rotate it until it feels secure and low-profile.

What sizes mean

We include 4 sizes:

  • 0: Extra Small
  • 1: Small
  • 2: Medium
  • 3: Large

Each tip is labeled L and R.

Step-by-step fit routine

  1. Start with size 2 (Medium) in both ears.
  2. Insert the Sleepbud gently until it seals.
  3. Rotate the Sleepbud slightly so it sits securely in your ear (this helps comfort and stability on a pillow).
  4. Do a quick comfort test:
    • Talk out loud
    • Move your jaw
    • Lie on your side and roll gently on your pillow
  5. Adjust tip size based on what you feel:
    • If it feels loose or sound leaks in, try a larger tip.
    • If you feel pressure, soreness, or a “plugged” feeling, try a smaller tip.
  6. It’s normal to use different sizes for each ear.

Quick fit troubleshooting

  • One ear feels quieter than the other: reseat the tip and make sure the earbud is fully inserted and rotated into place.
  • Ear hurts after 30–60 minutes: try a smaller tip and reseat; discomfort is usually fit-related.

How do I use Sleep Sounds vs streaming?

Question: What’s the difference between built-in Sleep Sounds and streaming?

Answer: Built-in Sleep Sounds are our noise-masking sounds designed for sleep and can be used phone-free once set up. Streaming lets you play anything from your phone like normal Bluetooth headphones.

Option A: Built-in Sleep Sounds (noise masking)

Best for: blocking and replacing bedroom noise all night

How to use

  1. In the Ozlo app, pick your Sleep Sound.
  2. Set your volume in the Ozlo app (phone volume buttons won’t control built-in masking volume).
  3. Put in Sleepbuds at bedtime and start your Sleep Sound.

Phone-free mode (built-in Sleep Sounds)

Best for: nights when you don’t want Bluetooth or a phone connection

How it works

  • Once configured, you can set Sleepbuds to automatically start your selected Sleep Sound when you take them out of the case, without staying connected to your phone.

Option B: Streaming audio over Bluetooth

Best for: podcasts, audiobooks, music, videos

How to use

  1. Connect in the Ozlo app.
  2. Start playback in your preferred audio app (Spotify, Audible, YouTube, etc.).
  3. Use your phone’s volume buttons to adjust streaming volume.

How do alarms work (and will they work without my phone)?

Question: Can I wake up with an alarm without waking my partner?

Answer: Yes. Our alarm is a private in-ear alarm.

Question: Will the alarm still work if my phone is not connected?

Answer: Yes. Our alarm is designed to work even when Bluetooth is disabled, because it is stored locally and runs on a real-time clock.

How to set an alarm

  1. Open the Ozlo Sleep app.
  2. Go to Alarm.
  3. Set your time and preferences.
  4. Confirm the alarm is saved.

If an alarm didn’t go off (fast fixes)

  1. Delete the alarm and recreate it.
  2. Open the case and wait about 10 seconds before removing Sleepbuds (this helps everything sync).
  3. Reboot the case: put Sleepbuds in the case, close the lid, wait 30 seconds, then reopen.
  4. If you don’t need streaming, use Bluetooth Disabled or power-saving mode at night for maximum reliability.

How do Sleep Patterns work and what about privacy?

Question: What is Sleep Patterns?

Answer: Sleep Patterns gives you insights about your sleep and your sleep environment, using sensors in the Smart Case and Sleepbuds.

What Sleep Patterns can track

  • Sleep duration and consistency
  • Environmental signals such as sound level, light, temperature, and pressure (depending on settings)

How to sync Sleep Patterns

  1. After a night’s sleep, put Sleepbuds back in the case.
  2. Open the Ozlo app.
  3. Tap Sync Now.
  4. Wait for syncing to complete (it can take about 1–2 minutes per night of stored data).

How much data we store before you sync

  • Sleepbuds can store up to five nights of sleep data before syncing.

Privacy basics (plain language)

  • For environmental sound, we measure sound level (amplitude). We do not capture speech or audio content.
  • You control what sensors are enabled in settings.
  • We do not sell consumer health data.

Morning routine: what to do after you wake up

Question: What should I do every morning?

Answer: Dock, charge, and sync (if you use Sleep Patterns).

Morning steps

  1. Put Sleepbuds back in the Smart Case.
  2. Close the lid to power down and charge.
  3. If you use Sleep Patterns, open the app and tap Sync Now.
  4. Keep the case plugged in when possible so you’re always ready for bedtime.

Cleaning and care (weekly)

Question: How do I clean Ozlo Sleepbuds safely?

Answer: Clean weekly. Wash ear tips with mild soap and water, and clean earbuds and case with dry tools only.

Weekly cleaning steps

  1. Remove ear tips.
  2. Wash tips with mild detergent and water.
  3. Rinse thoroughly and let tips dry completely before reinstalling.
  4. Clean the earbud nozzle using a dry, soft cotton swab only.
    • Do not insert anything into the nozzle.
  5. Clean charging contacts carefully with a dry cotton swab.
    • Do not wipe or press hard on charging pins (they can bend).
  6. Clean the case with a dry cotton swab.

Troubleshooting: the fastest fixes

Fast fixes checklist

  • Keep your phone within 10 feet (3 meters) of the case.
  • Try built-in Sleep Sounds to see if the issue is only with streaming.
