Ozlo Sleepbuds® 2 – Sleep Earbuds for Snoring & Noise Masking, 14-Hour Battery, Bluetooth 5.3, Blue

Overview

Create a calmer, more consistent sound environment at bedtime with the Ozlo Sleepbuds® 2, ultra-compact wireless earbuds engineered specifically for sleeping rather than conventional daytime listening.

Instead of using traditional Active Noise Cancellation, Sleepbuds 2 combine a comfortable passive acoustic seal with precision noise-masking sounds designed to cover disruptive noises such as snoring, traffic, voices and other sudden nighttime sounds.

Each Sleepbud measures only 11 × 17 × 12mm and weighs just 1.6g, with a low-profile shape designed to remain comfortable even when sleeping on your side. Four sizes of soft silicone tips are supplied to help create a secure, comfortable fit.

Sleepbuds 2 provide up to 14 hours of continuous playback on a single charge, while the Smart Charging Case stores enough additional power for approximately 2–3 extra charges, helping support several nights away from mains power.

They can also stream ordinary Bluetooth audio from services and apps such as Spotify, Audible, YouTube and Netflix before bed, then automatically transition to stored noise-masking Sleep Sounds according to your selected Sleep Mode.

Key Features & Benefits

  Sleepbuds 2 use specially tuned masking audio together with the passive seal of the silicone ear tips to reduce the impact of snoring, voices, traffic and other disruptive sounds.

  Unlike conventional music earbuds, the low-profile construction is purpose-built to minimise pressure against the pillow and remain comfortable during overnight wear.
• Ideal for Side Sleepers – Just 1.6g Per Earbud
  Each Sleepbud weighs approximately 1.6g and stands only around 11mm high, helping it sit discreetly in the ear instead of protruding like many standard wireless earbuds.

Why Choose Ozlo Sleepbuds 2?

The biggest difference between Ozlo Sleepbuds 2 and conventional noise-cancelling headphones is that Ozlo designed the entire system specifically around sleep.

Large over-ear ANC headphones can be uncomfortable in bed, while many conventional true-wireless earbuds protrude from the ear and create pressure when your head rests against a pillow. At just 1.6g per earbud with an 11mm-high low-profile design, Sleepbuds 2 are specifically engineered around overnight and side-sleeping comfort.

Their approach to unwanted noise is also different. Rather than trying to create silence using electronic ANC, the silicone ear tips passively reduce outside sound while carefully designed masking audio covers the sounds that remain. Ozlo specifically positions the system for disturbances such as snoring, traffic, voices and sudden environmental noises.

They also provide considerably more bedtime flexibility than a basic white-noise earbud. You can listen to a podcast or audiobook as you fall asleep, automatically transition to masking audio, use locally stored Sleep Sounds without continuous streaming, block phone interruptions through Sleep Shield and wake using a private in-ear alarm.

With up to 14 hours of playback and another 2–3 charges stored in the Smart Case, Sleepbuds 2 are designed around all-night use rather than short daytime listening sessions.
