There are many fitness trackers that claim to help users log more sleep. Whether it’s through behavioral insights, data-driven trend analysis, or educational content, companies are eager to enter our bedrooms. The Muse S, now in its second generation, wants a place on your pillow.

Unfortunately, while the Muse S excels in real-time biometric feedback and meditation guidance, it left me with a lot less than 40 winks.

About this article: I tested the Muse S (Gen 2) for one week connected to a Samsung Galaxy A51 as well as an iPhone 11 Pro Max. The unit was provided by Muse, but Muse had no say in the direction or published content.
