With Sleepbuds 2, Sleep Patterns graduates from beta, bringing environmental insights to help you better understand and improve your sleep over time.

Up to 14 Hours of Battery Life

Optimized power management in both the Sleepbuds and Smart Case helps deliver up to 14 hours of playback, with additional 2-3 charges stored in the case for multiple nights of use.

Redesigned internal antennas improve connection strength, pairing reliability, and overall streaming performance.

Easier, More Reliable Charging

The Smart Case was redesigned to help guide Sleepbuds naturally into place for a more consistent charging experience and fewer alignment issues.

Smarter Recovery System

A new internal recovery system helps Sleepbuds boot more smoothly and recover automatically if interruptions occur.

Smart Case Button Controls

A new physical button on the Smart Case gives you quick access to key controls like play and pause of Sleep Sounds, and alarm snoozing, without needing to reach for your phone.

Enhanced Environmental Sensors

Improved light sensor design helps provide more accurate environmental readings for Sleep Patterns insights.

Higher Maximum Volume

We increased the maximum volume ceiling for users who need stronger masking against loud snoring, traffic, or noisy environments.

Improved Sound Quality

Updated sound tuning and an amplifier make both Sleep Sounds and streaming audio feel richer, clearer, and more immersive.
