Ozlo’s Sleepbuds 2 build on Bose’s sleep earbud legacy
Ozlo, a sleep earbuds startup founded by former Bose engineers, has launched Sleepbuds 2, an updated version of its debut product with improvements to battery life, Bluetooth connectivity and sound quality. The launch is significant as Ozlo's first major update since its original Sleepbuds, marking the company's shift from continuing Bose's legacy sleep-tech product into building its own independent sleep platform with ambitions in AI-driven sleep data analysis.
The new buds cost $279, a 12% price rise on the original, and offer 14 hours of battery life (up from around 10), plus a charging case holding two to three nights' worth of power and a physical button for sleep sounds or snoozing alarms. Ozlo says a redesigned antenna improves Bluetooth range and reliability, addressing a common complaint about the first model, while a new amplifier, personalised sound tuning modes and a "Sleep Shield" feature to block calls and notifications round out the update. The buds also expand sleep-tracking insights, monitoring breathing, movement and room conditions such as noise, light and temperature, and ship with ear tips, a charging case and a USB-C cable, with a sleep mask and travel case offered as a launch promotion.
In short
- Ozlo launches Sleepbuds 2, priced $279, up 12%.
- Battery life rises to 14 hours; Bluetooth reliability improved.
- Adds AI-driven sleep tracking and new Sleep Shield feature.
Explained simply
Sleep earbuds are small audio devices designed to be worn at night to help people sleep, either by providing soothing sounds or monitoring sleep patterns. Ozlo, a startup founded by former engineers from Bose, has launched an updated version of its sleep earbuds product.
Bose, the audio equipment giant, once made sleep earbuds but no longer manufactures the product. This created an opportunity for companies like Ozlo to establish themselves in the emerging sleep technology sector.
Rather than simply copying Bose's approach, Ozlo aims to build a broader "sleep platform" that extends beyond just audio hardware. The company plans to use artificial intelligence to analyse sleep data and provide personalised insights into sleep quality.
