Ozlo Avaliações 

I was looking for earbuds that could sit flat in my ear so I could sleep comfortably and listen to my meditation. I was willing to put up with having to have the case close by so they can function well. Worked like a dream for 6 months then it all fell apart. The left ear became very low in volume. I reached out and was given all these steps to follow to no avail. Then came the issues with connectivity - I would have to wake up several times to reconnect them. Again a whole set of steps for me to follow to fix it. Finally, exasperated that the problem was not getting fixed I insisted on a them getting looked at . The response- silence . Absolute total silence. This makes me believe that this is a scam. I now have a $500 set of relatively nice looking ear plugs. Very expensive lesson!

I rushed to order my earbuds at the end of 2025 based on vendor messages that their sale was supposedly ending in 2025. I didn’t want to miss this sale as these earbuds were said to be the to
be the upgrade/replacement for the Bose sleepbuds.

It turns out the sale still hasn’t ended (as of February 2026) and I was unable to use my 2026 FSA funds for this purchase.
OZLO customer service is only via email and non responsive.
Examples of my low rating are that I referred someone to buy these earbuds, I never received my referral credit and the person I referred to buy these earbuds received a pair a set that stopped working in less than a month.
The earbuds are comfortable and have decent sound quality but are nowhere worth the high price tag.

I would love to post a review online on the vendor’s website but their customer service manages these posts and they refuse to respond to my feedback or post my review.

I regret this purchase.

These buds are great for sleeping, comfortable, block/mask noise well.
Sadly the batteries are un reliable, and I have had 2 sets fail over the last couple of years.
The second set failed just a few months out of warranty.
Ozlos customer and technical support are absolutely terrible for such a premium priced product. The only method of contact for both functions is an email address that appears to be sporadically monitored at best, with waits for replies measured in days or weeks.

I wish I could be more positive about this product, as the initial impressions are great.
Sadly let down by reliability and support issues.

Save your money

Edited 31-3-2026:

After posting this review, Ozlo did contact me and sent me a replacement left earbud, and this has restored full functionality to my product.
I am very happy to be able to use my sleepbuds again, and they really are good at what they are designed to do.
I was assured that any further problems will be addressed in a much more timely manner, and hopefully will never have to trest this promise.
I will add a couple of stars to my rating, but I will continue to warn anyone considering these buds.
Until there is a better support policy promised to all buyers (non-insured), I amend my "avoid" recommendation to "buyer beware"

Great quality, comfortable fit and enjoying the masking noise sound options (I would like to see a white, pink, brown label against each sound). The inbuilt alarm is also cool. Has reduced the amount of awake / disturbed time and how many times I get up at night. Also reduced the impact of my tinnitus. Very happy

A great upgrade on the Bose

Both my husband & I got the Ozlo ear buds. We really like them. I think it takes a little while for your body to get used to them. Now we sleep very well. In fact getting up in the morning can be difficult. If you get up to the loo in the night getting back to sleep is relatively easy.

The sound quality is great and the different sizes make such a difference. I really love my Ozlosleep buds.

Worst software I've ever encountered! After following multiple steps by developers and other individuals who have had the same issues I simply ... gave up!
I am relatively good with technology and completely understand all the steps for 'pairing' etc. The problem is that once one device is paired the Ozlo overrides and you need to constantly reconnect. Got everything working as it was designed. Example: Watch a youtube video, then turn it off and the Ozlo should automatically go back to white noise sound. (or vice versa). This is what it is supposed to do. Seamless integration, perfect idea. Until you turn one of the devices off AND you need to reset and repair (following 10 + steps). Not bad for me but literally impossible for most people looking to plug and play. Bluetooth connectivity is the issue and dominance by the Ozlo system causes glitches. We returned this as it was just not ready for the masses. Sad really as the ear buds are really well designed, fit nice and very comfortable for side sleepers. Their software team needs to work on the glitches before charging so much!

They DO NOT mask snoring at all. For that they are useless. Also, customer service needs significant improvement.

One of the sleep buds died after a firmware update, I almost never use that sleep bud as I use the other ear... Support gave me the run around, said they would forward it to some other team. Have not had a response in over a week. I'd strongly advise anyone to look into other companies.

Horrible.
Stopped working and customer service is a joke.

SOOOO frustrating. The connectivity is brutal despite factory resets, resetting the buds, forgetting the device etc…. I’ve had them less than 6 months and I’d return them if I could.

We purchased two pairs of Ozlo Sleep buds and they will not pair so are not useable. We have watched every video, followed all instructions including resetting the case and buds, deleting and resinstalling the app, unpairing etc. Multiple emails and phone calls to company have gone unanswered.

My Ozlo buds worked fine for over one year. I even recommended them to several people. However, the right bud stopped working and I contacted the company. They asked me to go through a few steps to try to get it working again. None of these steps worked and we decided that I would buy a new right side ear bud. I paid for it and was told that it was delivered. It never was delivered, and I was then told that my issue would be escalated to their " order escalation team". I assume there is no such team as I never received any other response and they do not return emails anymore. It has been one month since I first contacted them with my ear bud problem. That in itself is far too long but I gave them the benefit of the doubt that they were actually trying to help. I was wrong. I called my credit card company and got my money refunded and ordered another set of sleep buds from another company. Ozlo does not want to help with any issues and do everything to delay and put off any problems. There are several other reports of similar experiences from other people, so this is not just a one off from one disgruntled client.

II ordered a pair on the 28th of November order numberOZEU17602 they were due to arrive on the 6th of December sent by FedEx which never arrived. I got in touch with them and very kindly send out a new pair because the old ones were lost. The customer service was very good and I will update the headphones once I'vevhsd them for a couple of weeks. Very happy with the quick response and replacement.

After less than one year, the audio quality dropped considerably with the left ear bud going 100% dead. Ozlo’s customer service offered poor advice on how to fix the issue, but none of the suggestions helped. For example, after deleting the app and reinstalling as advised, the app no longer allowed the buds to pair with my iPhone. I’ve spent about $300 on sleep buds that don’t work as promised. Save your money by buying something else.

updated review
After months of backwards and forwards with Ozlo, my earbuds were finally labelled as faulty and have been replaced.

While the product itself does what it says on the tin (provides comfortable noise cancelling earphones even a side sleeper can use) the execution of the overall product does seem to be hit or miss.

My first faulty set wouldn’t update without a laptop, and without the update I couldn’t even get them to connect to my phone. It had a faulty charger case that would barely do a single charge before going dead and then would be tempermental on whether it would work or not.

The second replacement set has significantly better battery life, even after using the buds all night they still were going in the morning and the case had enough to charge them up ready to do again, it connected and updated with my phone no problem on first attempt, and doesn’t have any issues with charging either suggesting that the one I had was indeed a dud unit. Now they’re working properly I can say they’re a good product, however it would be nice not to need the case to connect to Bluetooth.

Ozlo do need to get better with the speed an issue is troubleshooted and replaced as it’s now very clear to me that my original should have been replaced months ago. It took months of backwards and forwards and a secondary issue appearing before they agreed to replace them. Most of the time was spent with them repeating the same instructions again and again despite me already confirming the issue was intermittent and never permanently resolved the problem. The founders are ex bose - they might want to learn from them a little more for warranty replacement programmes. It took 5 months for me to get a replacement despite the issue being raised in the first 30 days. Because of this I can’t give 5 stars.

Bought these around a month ago, can't believe it took me this long. Gone are the days of starring at my ceiling at 5am, wondering how I managed to score a place under a neighbour whose stomps could be likened to bigfoot.

It works as its supposed too, and rate it for what its meant to be - sleep buds and nothing else. Don't expect amazing bass, seamless on-the-go bluetooth or practical running buds; cause thats not what they're meant for. Optimal when used with its in-built sleep sounds, and extremely comfortable to sleep with. I get around 3 nights before needing to charge the case again.

Above this, I missed out on a traveller case to my dismay. Ended up emailing the support team, who not only went out of their absolute way to not only ship me one when they got stock, but monitored the shipment until it arrived.

So I can't recommend Ozlo enough, as I've done with family and friends so far since getting these bad boys. I only hope the team stays consistent with their service, and look towards updating the app with new content by routine.

Thanks again guys, happy I stumbled these buds.

This is the first time I’ve ever written a negative review, but my experience with Ozlo has been so disappointing that I feel I need to share it.

I purchased Sleepbuds directly from them, but never received an order confirmation email or order number. My credit card statement clearly shows the purchase, yet without an order number their customer service has been unwilling or unable to help me.

I requested a return within the stated timeframe because the buds are not comfortable for me as a side sleeper (though I will say the noise blocking is excellent). Despite this, I’ve spent over 3 ½ weeks sending countless emails and online forms, providing all of my details repeatedly, but I am still no closer to receiving a refund.

It is impossible to speak with a real person, and I’ve even received multiple emails saying my case is closed—despite nothing being resolved. I am now left £299 out of pocket, with Sleepbuds I cannot use. You would not think it was rocket science in this day and age for them to trace the order using my name address order email address and the copy of my credit card statement that I have sent them several times including all payment details. Frustrating to say the least.

Would I recommend Ozlo Sleep or their customer service? Absolutely not.

I bought these about a week ago. Had one minor order issue and found the customer service (Renz) friendly and helpful. They resolved it in a couple of days. The sleepbuds themselves are terrific and comfortable, even when I sleep on my side. I like the different white noise options.
