    They work

    I bought them mainly to deal with snoring, and they’ve been very effective. I also have tinnitus, and the experience depends heavily on choosing the right sound and, especially, the right volume. Using the wrong sound or setting the volume too high can worsen tinnitus and interfere with sleep. I found that a softer, steady sound, like Misty Rain at a low volume, works very well. One improvement I’d suggest is adding guidance for tinnitus users in their setup instructions, as well as a way to adjust volume without opening the phone app, which can be inconvenient when you’re already trying to fall asleep.

    Perfect Bose replacement

    Those are the perfect replacement of the Bose sleepbuds that are no longer in production, with extra features. Battery lasts whole night, no connectivity issues, added benefit of streaming. Block outside noise like they should, fit is the same as Bose, without the Bose issues.

    Lifesaver!

    You’ve saved my life, or at least my sleep, my health and my sanity.

    From severe sleep issues to now looking forward to bedtime. Still waking up in the middle of the night sometimes but it only makes me smile cause then I can listen to my favourite audiobook until I fall back asleep.

    Thank you for making these sleepbuds!

    Worth every penny!

    Game changer

    I was skeptical that the Oslo sleep buds would drown out my wife’s snoring. They have worked like a charm. We’re able to once again share the bed without one of us having to move somewhere in the middle of the night. They are comfortable for a side sleeper. I’m I’m very happy that I made a decision to try them out.

    Best Sleep

    Only thing that helps me get a good nights rest. Was heartbroken when Bose stopped their Version, so relieved when these came out. And so far better than Bose: less bugs and more comfortable.

    Great!

    The sleepbuds are great and have enabled me to sleep through my cat's meowing in the early hours of the morning when she thinks it's time for the day to start. They have also helped me get back to sleep more easily when I wake in the night as the consistent white noise keeps my brain in a more relaxed state. I have, however, found that the connection between the buds and the app can be a little finicky at times. I have it set to switch from streaming to white noise when the sleepbuds sense I have fallen asleep (which is an awesome feature) and, even though they generally do, a couple of times this has not happened. I was also disappointed to learn that the app does not yet track sleep data which is inconsistent with what I had read about the sleepbuds. Hopefully that upgrade is coming soon as that was the other reason I purchased these as opposed to a cheaper pair.
