QUICK SUMMARY
Ozlo has launched the Sleepbuds 2, its next generation of sleep earbuds.
Priced at $279, the Ozlo Sleepbuds 2 use noise masking technology to reduce sleep disruptions, and have a redesigned audio system for better music and sleep sounds listening.
Ozlo has released its next generation of sleep headphones, the Ozlo Sleepbuds 2. An advancement on the original, the Ozlo Sleepbuds 2 come with better sound quality, a smaller, more comfortable design and up to 14 hours of battery life – although the price may still come as a shock.
Made by Bose engineers, the original Ozlo Sleepbuds came out in 2024 to much acclaim, thanks to its advanced sleep and audio technology. While it won many points for its design, sound variety and comfortability, the price and app needed a bit of work, as I discovered in my Ozlo Sleepbuds review.
Ozlo has clearly taken these factors into consideration with the new Ozlo Sleepbuds 2. With the same design as its predecessor, the Ozlo Sleepbuds 2 have a smaller size, making them the world’s smallest sleep earbuds to date. Made from silicone, the Ozlo Sleepbuds 2 fit snugly in the ear and are designed for all-night comfort, especially for side sleepers.

Rather than completely block out noise, the Ozlo Sleepbuds 2 use noise masking technology to reduce disruptions like snoring or external noise. The earbuds have also had its audio system redesigned with a built-in amplifier, so the sound quality is richer and masking is stronger. Users also have more volume options.
To help you sleep better, the Ozlo Sleepbuds 2 come with a library of soundscapes and masking sleep sounds. The earbuds can be used to play music, podcasts and audiobooks, and they have a private in-ear alarm to wake you up in the morning.
The Ozlo Sleepbuds 2 have five customisable sleep modes to choose from, so you can decide how your audio runs through the night. For example, you can play music or an audiobook before bed and set the Ozlo Sleepbuds 2 to transition to noise masking sounds when you fall asleep or after a certain time.
When the Ozlo Sleepbuds were launched a couple years ago, the earbuds didn’t have sleep tracking, but that has now changed. The Ozlo Sleepbuds 2 and its Smart Charging Case track sleep and environmental conditions through the night, like breathing, movement, sound, light and temperature, and offer personalised insights in the app.

The real standout feature, though, is the improved battery life. The Ozlo Sleepbuds 2 now has up to 14 hours of battery life, which Ozlo claims to be the “longest battery life in the sleep earbuds category”. The case also stores battery for up to three sleeps per charge.
Other features include improved Bluetooth connectivity, and a Sleep Shield which blocks disruptions, like calls and notifications.
The Ozlo Sleepbuds 2 are available to buy for $279 at Ozlo. Compared to other sleep headphones, the Ozlo Sleepbuds 2 are definitely high-end, although with this purchase, you get the earbuds, travel case and the Ozlo Sleep Mask as a limited time gift bundle. As of writing, the Ozlo Sleepbuds 2 aren’t yet available in the UK and Europe.
