How the heck do you pronounce "Meizu", anyway?

I'm Chinese and I believe that 'Mayzoo' is the most close pronounciation to the original Chinese sound

StCharles is right. You just need to add the intonations in, and you'll be right. (4th tone for May, 2nd tone for Zoo).

does the pronounciation is now more accurate or bijective?
You motly all forget about the fact that in every language the pronounciation is diffenet. zoo in english is pronounced 'zu' in german 'Zo' and in chinese maybe different. So maybe we all stick to one pronounciation method, the International Phonetic Alphabet.
