Our dream was to revolutionize sleep for everyone, and make Sleepbuds as future-proof as possible. We took a bold step by using cutting-edge chips in our Sleepbuds—making us one of the first to do so. Being pioneers is exciting, but it isn’t always smooth, and we hit some bumps with Bluetooth reliability.

With this update, we feel like we’ve finally delivered the Bluetooth reliability we, (and you) expected from us and your Sleepbuds.Today, we’re rolling out the quick approximately 15-minute update, to keep your sleep smooth and reliable.

Improvements:
• Faster, more reliable Bluetooth
• Better re-connection performance

Bug Fixes:
• Alarm bug squashed
• Update process smoother

Note: This release includes critical performance improvements, Sleepbuds on firmware version 01.03.2410006 or older will be required to update.

Thank you for believing in the dream of Ozlo Sleepbuds and trusting our team to deliver it to the world.
