Sleep earbuds aren’t for everyone, but when you need something to block out the world—or worse, snoring—without putting your ears through some kind of pain trial with regular wireless earbuds, they’re huge. For context, the Soundcore Sleep A30 get about 9 hours of battery life in local mode with noise-canceling activated. Like previous Ozlo sleep earbuds, the Sleepbuds 2 track sleep efficiency and duration, but the new buds also expand on tracking abilities. Not having used these sleep earbuds myself, I can’t say for certain how well those features work. As long as we’re comparing to other sleep earbuds, I should note that the Ozlo Sleepbuds 2 don’t have active noise cancellation, unlike the Soundcore Sleep A30.
