    Couldn’t live without them!

    I was a previous Bose sleep bud convert- mine were still working! But I figured they would surely give out at some point so decided to give the Oslos a try. I’ve had them for 3 months and I’m finding them great. I read reviews before I bought them and was a bit worried about the battery life and connectivity issues- so far, they have worked perfectly. I’m enjoying being able to listen to a podcast to fall asleep, and definitely sleeping much better than when I wasn’t using them. I wasn’t using the Bose ones for a while before I got these and I definitely notice a difference- my sleep app from my watch shows a noticeable improvement! They totally work for blocking snoring for me, and just improve my sleep in general. Couldn’t live without them now!!

    Excellent product and outstanding customer service

    I’ve never slept better! I lost a bud and they responded immediately and installed the replacement for me. Truly never experienced such personalized, helpful and responsive customer service. Would recommend to everyone who has ever used a noise machine.

    Sono perfetti

    Ho acquistato gli Ozlo Sleepbuds e ne sono davvero soddisfatto. Da quando li uso non mi sveglio più durante la notte a causa dei rumori. Sono comodi, leggeri e funzionano esattamente come promesso. Un acquisto che ha migliorato la qualità del mio sonno.

    Worth the extra money!

    Love them! One thing I love is how I can program them to play music or books or whatever on my phone for a while (I’ve chosen 45 minutes), and after that I can choose how long the sound I’ve chosen from the app continues!

    This wasn’t even mentioned in the reviews I watched but I love it!

    The case is heavier, feels more luxorious and easier to keep track of than soundcore. It’s also easier to get the headphones in the right place to charge them which wasn’t as easy with soundcore.

    Sound wise they feel the same as soundcore but as the Ozlo buds have the Bluetooth in the case the range isn’t great, if you want to walk around even a few meter you need to bring the case.

    They fit my ear perfectly and don’t fall out at night.

    I used Soundcore for a few years but they just didn’t live up to my expectations and I couldn’t get hold of extra parts, like new silicon buds in Sweden.
