Ozlo has unveiled the Sleepbuds 2, sleep-focused earbuds that prioritize a smaller design and longer battery life. The new model is priced at $279 and is now available on Ozlo’s official website.
Ozlo Sleepbuds 2 Specifications
For a device intended to stay in your ear for eight hours or more, physical dimensions are the primary constraint. Ozlo says that the Sleepbuds 2 are the smallest in their category, measuring 11mm thick and weighing 1.6 grams per earbud.
By comparison, standard wireless earbuds like the AirPods Pro 3 weigh over 5 grams, and sleep-focused competitors like the Soundcore A30 weigh 2.4 grams. The low-profile design and soft silicone tips are engineered to sit flush against the ear, which is a necessary design choice for side sleepers who typically experience pressure when wearing standard earbuds against a pillow. These also carry an IPX4 rating to handle sweat.
Rather than relying on active noise cancellation (ANC) to block out environmental sounds like snoring or street traffic, the Sleepbuds 2 use a combination of passive isolation and adaptive noise-masking audio. They connect via Bluetooth 5.3, allowing users to stream audio from standard apps like Spotify, Netflix, or Audible.
When a built-in accelerometer detects that the user has fallen asleep, the earbuds automatically fade out the Bluetooth stream and switch to locally stored noise-masking soundscapes. The earbuds do not include a microphone, as they are built strictly for sleep, but they do feature a private in-ear alarm designed to wake the wearer without disturbing a partner. For those who prefer to limit wireless signals at night, there is also a Bluetooth Disabled mode.
In terms of battery life, the Sleepbuds 2 offer up to 14 hours of playback on a single charge, while the Smart Case provides an additional two to three recharges. The case also includes sensors that monitor ambient noise, temperature, and light, with the collected data integrated into the Ozlo app to provide sleep environment insights.
In related news, Machenike has recently launched the TH66 earbuds, offering ANC, 40ms low-latency gaming mode, and up to 7 hours of battery life at an affordable price.
