I think the underarms would be fine if I had ordered my regular size (L). Oh and here?s the extra bonus: they cover the bunion. I can wear these for hours and even walk in them without being in pain/crippled. Ive decided to return these. This things are actually terrible. I listen to a lot of music while Im on the internet. Been using this product non-stop for the past week and couldnt be happier. Vaya, no estoy diciendo que con otros audífonos de gama inferior no se vayan a apreciar todos esos distintos sonidos, pero definitivamente estos ATH llevan la experiencia a otro nivel bastante superior. - The cable is really long I think is about 2 meters(even more). In the Backbeat app you can assign when switching to awareness mode the music would pause (which is a fantastic feature).
