If you have your iPhone's volume turned all the way up, however, you may hear a little distortion with the Late Night EQ. Some of the other EQ options give the volume a bit of a boost but none more so than Late Night. We've covered this trick to boost iPhone speaker volume before but it bears repeating: Head to Settings > Music > EQ and select Late Night. Just cup your hand around the speaker end of your iPhone so the sound waves can bounce off of your hand and toward your ears. This one is good if you are watching YouTube or otherwise holding your iPhone while attempting to listen to it. If you are listening to an iPhone propped up against something, then make sure it's propped up and upside down.
The speakers on your iPhone are on the bottom, so they're better able to kick out the jams, as it were, if they are facing upward and outward and not downward where they're muffled by your table, desk or countertop.
