Ozlo Sleepbuds 2 Launch at $279: 14-Hour Battery, Redesigned Sleep App, and Smart Case Button

Ozlo has officially launched the Sleepbuds 2 at $279, an iterative but meaningful upgrade to the original Ozlo Sleepbuds that builds on Bose's discontinued sleep earbud legacy. The new buds address the two biggest complaints about the originals: battery life and Bluetooth reliability.

What's New

• 14-hour battery: Up from roughly 10 hours on the original model — enough for even the longest sleepers and nappers
• Improved Bluetooth: Better range and connection stability, with new pairing controls that make initial setup less frustrating
• Smart Case button: A physical button on the charging case can now start a stored Sleep Sound or snooze the in-ear alarm without opening the app — a small but impactful quality-of-life upgrade
• Updated audio hardware: New drivers and more accurate sleep-tracking sensors
• Redesigned app: The Ozlo Sleep app adds Sleep Modes, Sleep Shield noise masking, and a larger sound library

How They Work

Unlike the Bose QC Ultra Earbuds ($152) or AirPods Pro 3 ($199), the Sleepbuds 2 are purpose-built for overnight use. They combine passive noise isolation with masking sounds rather than active noise cancellation — an intentional design choice that prioritizes comfort and battery life over audio versatility. You cannot stream music or take calls with these; they exclusively play sleep sounds and white noise.

What This Means for Buyers

If you struggle with sleep noise — a snoring partner, street sounds, or hotel rooms — these are the most purpose-built solution available. The $279 price is steep for a single-purpose device, but the 14-hour battery and case button solve real pain points. For buyers who want sleep features plus daytime ANC, the Bose QC Ultra Earbuds or AirPods Pro 3 are better all-rounders. See our wireless earbuds guide for full comparisons.
