Ozlo and Calm team up on limited-edition Sleepbuds to advance sleep tech

Ozlo just launched Sleepbuds with mental wellness app Calm. The Sleepbuds come in a distinctive Calm Blue colorway, pairing the company’s noise-masking technology with Calm’s sleep and mindfulness content.

More than a color update

Ozlo’s new Calm-branded Sleepbuds combine smart hardware with quality content to create what both brands are calling “intelligent rest.”

The earbuds integrate Ozlo’s existing tech — noise-masking sleep sounds, biometric sleep detection, and a design meant to stay comfortable all night — with Calm’s 300+ hours of Sleep Stories, soundscapes, and meditations.

iOS users get Calm Sleep Premium for a year, and Android users receive the full Calm Premium subscription.

The sleep stack evolves

Most sleep tech measures what happened while you slept, but does little to change the experience. Ozlo and Calm are trying to close that gap by pairing detection with tools that actually support rest.

“Sleep is a superpower,” says Greg Justice, Calm’s chief content officer, who sees combining Calm’s content library with Ozlo’s sleep tech as a way of enabling “people to fall (and stay) asleep more easily, ensuring they wake up refreshed and ready to own the day.”

By building Calm’s content directly into the Sleepbuds experience, users get both the diagnosis and a way to enhance sleep performance.

Part of a broader shift

This move fits a growing pattern: tech and content companies are building hybrid ecosystems that support both sleep behavior and recovery habits.

• Oura now integrates Headspace meditations with real-time biometric feedback
• Therabody licensed its TheraMind sound therapy to Oura
• Philips partnered with Kokoon on sleep headphones that adjust audio based on sleep stages
• Equinox Hotels designed full room protocols with Dr. Matthew Walker for temperature, sound, and light
