# Ozlo Sleep

> Ozlo Sleep is a Boston consumer-electronics company that rescued a product its own founders helped build at Bose. When Bose killed its cult-favorite Sleepbuds in 2020, three of the program's veterans licensed the intellectual property, raised venture money, and shipped their own version. Today Ozlo sells the Sleepbuds 2 - tiny sensor-packed earbuds that mask noise, track breathing and movement, and sense the room around you - while quietly turning a hardware brand into a platform for sleep data.
