You won't be able to use either of those on
Moodle cloud, because they will not be installed and you do not have the ability to install plugins there. (I think).
So you will need your own Moodle.
VideoEasy will do it. If you are not familiar with filters and how Moodle handle media links, its a bit of a learning curve. But basically:
i) Install the Video Easy filter
ii) set it to off but available and leave it in the default position
iii) make a template for the once player from a preset. Set it to handle MP3
iv) on quizzes where you want to use it, disable the Moodle multimedia plugins filter and enable the VideoEasy filter.
Then any mp3 files in the quiz will be displayed in once players and elsewhere on your Moodle site audio will play as normal.
This page briefly explains the process using the Poodll filter. But all the same steps apply to the VideoEasy filter too.
