Sleepbuds® 2

Key Benefits

• Blocks disruptive noise for a more restful night's sleep.

• Automatically switches to noise-masking sounds when you fall asleep.

• Provides all-night comfort with a secure fit designed for side sleepers.

• Tracks sleep and bedroom conditions for personalised sleep insights.

Ozlo Sleepbuds® 2 are purpose-built to help you sleep through disruptive noise, combining advanced noise masking, audio streaming, and smart sleep technology in a compact, comfortable design. Developed by the team behind the original Bose Sleepbuds, they are engineered to stay securely in place throughout the night, even for side sleepers.

Biometric sensors detect when you fall asleep and automatically switch from your streamed audio to built-in noise-masking sounds, helping minimise disturbances while conserving battery life. A gentle in-ear alarm wakes only you, while the Smart Case monitors your sleeping environment, including noise, light, and temperature, and delivers personalised sleep insights through the Ozlo Sleep App.

With up to 14 hours of battery life and a low-profile, all-night comfortable fit, Ozlo Sleepbuds® 2 help create a more peaceful sleep environment and support consistently better rest.

Sleepbuds® 2 use a layered noise-control system designed specifically for sleep, combining a secure in-ear seal with noise-masking sound to reduce disruption from snoring, traffic, neighbours, pets and other irregular nighttime noise. Rather than relying on active noise cancellation, the buds create a stable sound environment that reduces sudden changes in noise that can disturb sleep. Their ultra-small, low-profile shape is engineered for all-night comfort, including for side sleepers, with four sizes of soft silicone tips for a secure fit. Biometric sensing and intelligent noise masking work together throughout the night, helping you stay asleep for longer with fewer sound-related disruptions.

Quality sleep is essential for health and performing at your best, yet it remains a struggle for many. To solve this, Ozlo has assembled leading mechanical, electrical, audio, and software engineers to create smarter, non-pharmaceutical solutions. By combining science and technology, they develop innovative products that use audio to enhance rest, helping people achieve better, more restorative sleep.
