5 5E. I also have multiple sclerosis. it started to tear ! The scent is definitely different too. This shoe rack perfect. I just have to pull up at each side to give my "ear a chance to breath" for a second or two and then its not bad . I have since replaced it with a HyperX Cloud headset and I recommend that absolutely no one buy this. Not good love it but broke the sane day sorry I needed this cable to replace a broken one from my headphones for my oculus headset. Excelente material, muy cómodas y suaves, no se deforman.
