I bought the best sleepbuds I have ever worn however my sleepbuds have stopped working within the warranty period and getting a useful response from their customer service team is impossible. I was worned not to purchase this product because of this issue and I am now regreting my decision. There is no phone contact, multiple emails go unanswered with copy and pasted unhelpful problem solving responses. The enormous price you would think the customer service would be better.

This company has the worst customer support I believe I have ever experienced in relation to the immense cost of the product. They don't have a phone number to call so you have to wait eons for an email to arrive to provide instructions. Further they requested videos despite explicit verbage of the problem then didn't confirm that videos were received. I had purchased the earbuds April 10th. May 3rd I experienced issues with case not turning on, the lights were not responsive. I performed basic reset steps indicated in FAQs and no change. May 4th I sent initial ticket with issue. I received a response with steps that I had already explained that I had performed but would do again and sent another reply that these steps were completed with no change. May 6th I followed up asking for an update. They replied May 13th requesting videos of the problem be sent via email. I sent videos (I was delayed due to illness) May 18th. I still haven't received a reply. I again requested an update and I have been ghosted with a bricked product that doesn't function. It was an amazing product for 2.5 weeks then a sudden malfunction. I'm furious but I can't do anything about it. Don't purchase Ozlo, the customer service is terrible. If I could give zero stars I would.

I'd like to give these earbuds a higher grading but they are just too flaky when it comes to the power management...discrepancies of earbuds draining differently while the case is connected to usb power source (left earbuds draining while not in use) leads me to believe that they don't know what their doing (allegedly former bose engeneers). 2026 and we still don't have a good enough solution).

I was genuinely happy with my Ozlo Sleepbuds at first. Let me start by saying it's a wonderful product and they are very comfortable in the ears. However, my earbuds only worked for 2 months. There is no number for support, despite the fact that the website states 24/7 support. Yes, you can email them 24 hours per day, but who knows when you will hear back from them. My right earbud stopped charging. I emailed support and did get a reply the same day. They asked for the order number, videos and photos which I happily sent. The reply back was the exact same request to send the videos again. When I resent them, no response. They sent a video on how to hard reset the earbud, which I also followed and still they will not work. I spent over 2 hours on this and still no reply of if they will honor the one-year warranty and refund me for the product or pay for the new pair I had to order. I didn't want to wait 10-days for a reply (as others have stated) before ordering a new pair, as I do rely on the white noise at night to sleep. The product is good (when they work) but customer support is sorely lacking. I hope that the ones I ordered on 5/14 will last longer than a two-months. That is ridiculous for a product that is marketed for $350! They should honor the 1-year warranty, and refund me for the price I originally paid, or pay for the new pair that I had to order. Ozlo - please do a better job with customer support and guiding customers if they need to return them if within the warranty period. I would like to leave a positive review for you next time and tell my friends about the sleep buds, but I can't until I know you will honor the warranty period.

There's a muffled sound coming from one of the sleep buds, and both sleep buds disconnect as soon as I take them out of their case. Ozlo support refuses to provide me with an address to which I can send my sleep buds for a refund, asking me to take pictures and to record a video of me using the sleep buds instead. This isn't going to happen as I'm done investing time in a product that is clearly not working. They can take all the pictures they want once they've received my sleep buds. It's also extremely frustrating having to wait for several weeks for yet another email reply from support in which I'm asked to take a picture and record a video yet again. This is fraudulent behaviour. Ozlo has no interest in honouring their warranty. Don't buy their product. Edit: The response by Ozlo is a complete and utter lie. They took 10 days to send me an email in which they asked me yet again to record a video and to take pictures of their product – something which I'm not obligated to do to make a warranty claim. Edit 2: After several weeks, they finally sent me a link to an online exchange form. Unfortunately, the form doesn't work. What a scam...

I am extremely disappointed with my Ozlo purchase. A major factor in my decision to buy was the advertised promotion for a free one-year subscription to Calm Premium. I even received a promotional email from Calm confirming this offer just two days before I placed my order. However, neither company will take responsibility. Calm states that Ozlo is responsible for sending the activation link, while Ozlo support claims it’s an "old promotion" despite the fact that I have time-stamped proof it was active when I bought them. It is incredibly poor business practice to advertise a premium feature to secure a sale and then refuse to honour it after the money has been spent. This is textbook false advertising. If you are buying these specifically for the Calm partnership, be warned: they may not honour the deal.

I was genuinely happy with my Ozlo Sleepbuds at first — for the first few months, they worked really well. Then the problems started. After a software update in July 2025, the range suddenly became terrible. The buds disconnected unless the case was right next to them. I received a replacement pair, but after only around 10 uses, the right bud suddenly became almost silent. I contacted support in November. They replied at first, but then simply stopped responding. No solution, no follow-up, no proper customer service — despite the product still being within the two-year warranty period. For a product at this price point, this is extremely disappointing. Great idea, but terrible reliability and very poor support.

This quite honestly might be the absolute worst experience I have ever had with a product and a company. Approximately 2 years ago I purchased these through their rental/finance plan. I received them and immediately upon receiving them they would not charge nor would they connect to my devices. I went through trouble shooting and was eventually told to return the headphones for a replacement. I packaged them up and returned them as instructed with the label THEY PROVIDED. Delivery was confirmed approximately 1 week later. I never received replacement buds as they said they would be providing. Fast forward two years later, I am being absolutely HARASSED by calls, texts and emails demanding $600 in payment for these headphones and being threatened by their "investigator" who states repeated "i will not be giving up until you pay your balance in full. You can not avoid me forever." As if THAT is professional. Hands down the worst product, worst customer service and worst experience i have ever had.
