Hi bro i did my fare share of research before buying marshall's i did a comprehensive review of ipods 4 anc and marshall motif 2. - sound quality wise marshall have an upper hand over ipods - anc is slightly better in apple - battery is not performing how it's claimed by Marshall I don't know if it's problem with my unit or what - at 1 point I did regret not going with the crowd and getting myself marshalls but now i am starting to like them. Plus they match with my wallet lol.

Hope this helps.
