The ability to connect the headphones via USB-A (which is larger than I would like) or via INCLUDED 3. They are close together. That should avoid any problems. So, please, BE CAREFUL with it. Unfortunately, the leather and sole are so stiff as too make the shoes a podiatrist’s nightmare. Luckily it had another layer of rubber protection for the wires and still remained fully functional. These socks were beautiful and if theyd fitted, Id have given them 5 stars. The Park base is nice and hefty and I have no issues with it. Otro punto muy a favor del Viper es que es super ligero. Everything fits together if you thoroughly plan for everything.
