I bought these because I thought they would be closed, meaning that music you listen would not be heard from the outside. This was important to me because I do not like to disturb those around me, also I like the 'privacy'. As big and padded as they are, they aren't closed. As for sound, the music sounded crisp- although I admit I didn't give it a thorough listen. I have an average sized head and the fit was pretty snug. My Sennheiser HD 202's oval shaped muffs are much more soft and comfortable, the circular shape of the S805's put pressure against some parts of the ear (unless you have circular ears!). The headphones seem very sturdy and well made. It was easy to pair with my Samsung Propel. Pretty good, but these will be going back.
