16 GBs are still nice for MP3s.
On the other hand is this really necessary to have .ogg or .wav for earbuds?
idk why ur comparing .OGG to .WAV
.OGG (Vorbis) is a lossy file and .WAV is lossless
comparing OGG to MP3 is a much better example
.OGG is way better than MP3 in terms of quality to size comparison when compressed. the only reason MP3 is still widely used now is because everything is compatible with it.
the difference in file size between OGG and WAV is INSANE, we're talking like 40mb on OGG to 400mb on WAV
also yes it is necessary. if you have good earbuds (IEM/In Ear Monitors) and good ears (like me), MP3 files do NOT cut it. the higher the quality and clarity of the audio, the nicer it looks and feels to me
