Ive tried to use a Neti Pot in the past and it was uncomfortable, gross, and made me feel even worse since all of the water wouldnt come out. Buying a second set right now for a family member! On a positive note, they fit nicely in the ear and the native Samsung Gear app gives the earbuds increased functionality when used with a Samsung device (in my case a Note 8). This really helped my husband. It didn?t come with instructions on how long to wear it at a time but you can find that information in abundance online.
