I use earbuds like this for sleeping. I wasn't expecting this pair to cover all of my needs. Several months ago, I purchased an inexpensive set...different brand...just to test out if this would help with my sleeping issues. They helped, until the headphones started playing a low battery notification about 5.5 hours in to use. So, I went in search of another inexpensive pair with longer battery life. I found some claiming up to 9 hours on a single charge, but like the first cheap pair...they gave a low battery warning in the 5-6 hour range. Had I not given the other cheap set to my almost 15 yr old and had she not lost them, I could have combined both sets of cheap ear buds for a full night's sleep. So, I bought these Rinsmola's, thinking I'd be swapping them out with another pair somewhere in the 5-6 hour range. I was shocked to find these still playing over 8 hours into a single charge!!! I have yet to hear any kind of low battery notification, so who knows how long these last. All I know is that I now have a solution for my husband's snoring while we're on vacation and a great way to block out the neighbor's barking dogs.
