I absolutely love my H9i headphones but this app is a different story. My headphones worked with my old Note 10 but not with my new S22 Ultra. The app works great and connects on my s22 ultra but the headphones will not pair to this phone no matter what I try. On my note 10 the app never worked but the headphones would at least pair and function so I didn't care. I'll change my review as soon as I can get my headphones to connect to the S22 Ultra.
