Sleep is a deeply personal thing. Nearly anyone you ask will have a different pattern, rhythm, feeling or complaint. Unfortunately, I have never been a great snoozer. I’ll be the first to admit: I’m fully jealous of anyone who can sleep through the night and wake up feeling refreshed. However, the Ozlo Sleepbuds are a sleep aid I just can’t do without.

Ozlo may be a newcomer to the sleep headphones space, but the company has a distinguished pedigree. Taking up the mantle from the excellent yet discontinued Bose Sleepbuds 2, three former Bose employees resurrected this cult sleep favorite by acquiring the Sleepbuds trademark — and created a similarly comfortable product, which levels up with all-night battery life and biometric sensing.

At $300, these sleep headphones are not a bargain. However, since the demise of the Bose Sleepbuds — my previous favorite sleep headphones — I have not found a better, more comfortable or more efficient way to block out nighttime noise.

The Ozlo Sleepbuds are a game changer when it comes to better sleep, offering unmatched comfort, a secure fit and superior noise masking. Designed for all-night wear, they block out disturbances like my husband's snoring and all types of ambient noise while allowing personal audio streaming that seamlessly transitions to sleep sounds.
