From my very cursory research it could depend on where in Vietnam the person is from. I only did the research because I stumbled over several youtube videos where people were like "you are stupid if you don't pronounce it win" but I thought the guy I knew at school should probably know his name better than random youtube person and he definitely pronounced it between 'n-Yen' and 'n-Youn(g)'.
