    The hype is justified!!

    I waited almost 4 weeks so review so that I could give an informed, balanced and honest review. If you're like me you're giving the decision to purchase a lot of thought. You're checking reviews and comparison products. Because of the price, which seems high, before you buy, you're on the fence. Don't be, jump it and get them!! I sleep 100% on my side, from one side to the other and they have NEVER come out or been uncomfortable. I love the fact that what you listen to going to sleep, turn off automatically and the ambient noise you've selected comes on and time you even semi wake up!! There are a great selection of sounds available and the silent alarm is fab. I am absolutely delighted that a bit the bullet and invested in myself because the Ozlo sleepbuds arw totally worth it, as am I!! I was a tad disappointed though that the membership to the calm app which is available free to US customers does not apply to EU customers. I can't see why we wouldn't get it but that has nothing to do with the actual product Im reviewing so it's a full 5☆ from me.

    Satisfied Customer

    I had previously used Bose and was disappointed when they ceased production. After a couple of years making do with supposed noise cancelling (expensive failure) and wax earplugs (good but well below adequate noise exclusion) I purchased the Ozlo ear buds on hearing of their introduction. I am pleased to say that they exceed expectations with regard to comfort, efficacy and updated software. I also thought they were reasonable value. It is important to note that I can’t comment on their durability at this stage having first used them in early January 26

    It made the difference

    Got Ozlo sleepbuds for about 2 weeks. I wanted to cover snoring. And it worked beyond my expectations. Had several good nights sleep.

    Excellent product

    My Bose sleep buds finally came to the end of their service and to my horror no longer available. Thankfully I found Ozlo and these are brilliant. I work FIFO (sleeping in a camp) which can be very hard to get to sleep. These are Super comfy, havegreat options of sound and have provided me great surety that I will be able to get to, and stay asleep. Excellent supporting app that is providing great sleep feedback also.

    I would recommend to anyone and everyone, money well spent.

    Fantastic product could use more battery life

    I love these headphones. They’re comfortable, sound quality is great and they have a ton of options. They also help me track my sleep better than anything else I’ve used {other apps and my Apple Watch}. The case is great for storage and charging, although they are hard to get seated just right in a hurry, you need to be very careful or they’ll be dead when you head to bed. I love that they have their own alarms so I don’t miss mine through the noise cancelation. In an emergency I can still hear enough to be woken if need be {luckily I haven’t needed} but they otherwise help mask most of the sounds in my house while I’m sleeping, which are many. They stay in place well with very good comfort while side sleeping. I sometimes place my hands next to my face and was worried I might feel them pushing but I never notice they’re there. My one and only complaint is the playtime on them. Each individual charge is short. 8 hours max and if I sleep any longer the sound shuts off and I wake up and have to switch to my non comfortable headphones for the rest of my sleep. A 10 hour battery life would be ideal for my days off when I might get more sleep than normal but for work nights where I’m sleeping 7-7.5 hours they work just fine. Allover I’d buy them again since it seems no other brands have better battery life and they all look much less comfortable.

    Great sleep buds.

    I particularly like the size options. The sound quality is excellent and I drop off like a light.
