BioShock Infinite: The Complete Edition

Same question.

You don't need to get them all in one playthrough. I missed a kinetoscope and voxophones in my first playthrough.didnt remember which ones I missed so I followed the guide and recollected them. It'll pop once you get the ones you are missing. Figured I'd answer the question since I had the same problem

If you don't want to start a new play through you can just go to chapter select and load the last chapter, go to your voxophone collection, see which ones you're missing by comparing to the list on the Bioshock wiki and just collect those by loading up the chapter where it should be. For extra help you could search for "Bioshock Infinite *voxophone name*" on youtube and you'll find a bunch of short and easy videos showing you where to find them.
