These wireless earbuds are by far my favorite pair I've ever had. I've purchased almost every major brand as I travel a lot for work, and these are super noise canceling, they have great sound quality and work wonders on phone calls. The app you can download allows you to adjust/change controls, like noise canceling levels, bass, treble and by genre. It comes with extra ear fit pieces to find the perfect comfortable size and the case is tiny. It fits in the front pocket of my jeans! I can't say enough great things!
