Before making a purchase, I always appreciate clear user guidance, and JSAUX includes some important warm tips. For instance, if your USB-C device already has a 3.5mm audio jack, this adapter might not support phone calls or music control functions on certain models like Galaxy S9/S8/S10 or some iPad Pro versions. This transparency helps set realistic expectations and prevents unnecessary frustration, which I value highly when considering a tech accessory.
