Whatever works best for you. Los siento mejor con calcetines por que la plantilla de los Northside es mas bien dura y yo sí necesito el "acolchonamiento" que el zapato NO trae. And I love that the racks are collapsible. Nothings as comfy, and even if you spent several times as much, itd be, in my opinion, both an incremental upgrade to the sound quality and a substantial downgrade to comfort. Not sure about battery life except that I havent had to recharge yet! Es de muy buen material, durable y resistente, desafortunadamente llegó con unos tornillos sin colocar y que no fueron posible poner en su lugar. The part that loops around the ear has made a lil bit of a sore spot but I think that is just my body getting used to something new! They are somewhat easier to come off. The bottom is plastic but seems solid and the keyboard doesnt feel like it has any worrisome flex to it. And its a night and day difference.
