Amazing buds that's really helped me sleep much better than ever. Astonishing software that has functions for everything you need and more. It is pricey but worth it 100 times over for sleep.

They are fabulous. I use the Ozlo sleep buds every night to drown out the sound of my husband’s snoring. Sometimes if I can’t sleep, I switch from the ambient sounds to a podcast or music on Spotify. They are the best.

I used to own the Sleepbuds from Bose and I am very happy that Ozlo has brought a further development to the market. At first I had connection problems with my Sleepbuds, but the support responded quickly to my email on a Saturday. With the help of a firmware update, everything now works perfectly.

Have been told the replacement for my faulty sleep-buds are on their way.....yaa!

If it would work it would be such a great product. Unfortunately the right earbud is constantly producing a tinnitus sound during playback, much like an outdated transistor, opposite of relaxing experience. Not usable. Multiple people have reported the same issues on reddit.

I had high hopes for Ozlo, given its $300 price tag and premium marketing. Instead, I got a buggy, frustrating product that feels like a beta test—and a customer support experience that made it even worse. Product Failures: - Basic features like adjusting volume or restarting white noise require the mobile app, which is a terrible design choice for a sleep product. - When the auto timer finishes, the earbuds disconnect entirely, forcing you to go through an absurd multi-step process (involving the case, app, and flashing LEDs) just to reconnect them in the middle of the night. This completely defeats the purpose of a sleep aid. - After a firmware update, connectivity got even worse. Customer Support Nightmares: - Sent multiple emails to support—got ignored for over 24 hours despite this being a $300 device. - When they did reply, my simple question wasn’t answered. Instead, they dumped a generic troubleshooting guide on me, making me feel like an unpaid beta tester. - I had to guess email addresses for leadership, still no response from them after 48 hours. Seems like they don't care. - Even after repeated follow-ups, I am in limbo waiting for a refund. For this price, a product needs to be damn near perfect—instead, Ozlo is a frustrating, half-baked experience with terrible customer service. If this were a $79 device, I might be more forgiving. But at this price, hard pass. 1/5 stars – stay away.

I complained of static in my new Ozlo Sleepbuds and also that they are too big to fit my ear canals. Their response was to try something else in spite of a 30-day return window. I have lost confidence in this new company and all I want is to return them and to be refunded.
