The earbuds are quite comfortable and stay in place better than my previous pair. The Bluetooth connection works, although not as smoothly as expected, and the app sounds are generally nice. However, after just a week of use at low volume and with default sound settings, I developed tinnitus. I've stopped using them, but the tinnitus persists, which is concerning. I strongly advise against these if you care about your hearing.

Ozlo was born from a shared frustration:
sleep shouldn’t be this hard.
After years leading innovation at companies like Bose, our founding team, including audio engineers, sleep researchers, and product designers, set out to create a solution that honored sleep for what it truly is: restorative, essential, and deeply personal.
Our breakthrough came not through noise-cancelling headphones or smart alarms, but by designing something radically different: small, comfortable Sleepbuds that blend science-backed, sound-masking audio with sensor-driven intelligence, helping people sleep better naturally.See more
