After using them for around 4 months, I would definitely return them if I had the chance. The battery barely lasts through the night while using Bluetooth, and the connectivity problems are incredibly frustrating. The range is inadequate; you have to be within about 3 meters of the case or else you lose the signal. It's an interesting design idea, but it falls short of expectations, and I cannot recommend them.

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
