Learning style do exist as individual learners have their own way or style to learn. This is the reason why teachers should know their students well to engage in different teaching pedagogies to cater different learning styles of learners.
Learning styles, or more accurately, "preferred" learning styles, is absolutely real. I have been working on developing my understanding, recognizing, and applying of style-based techniques with my students over the past few semesters. The results are quite impressive.
--I have advised confirmed Audio learners to not take notes during class, but to record the lecture or take photos while listening, and to write those notes later.
--I have advised confirmed Visual learners to take notes from the chapter beforehand, so that they are not consumed with note-taking and can focus on watching the notes. They can supplement their prepared notes with the lesson notes.
--Kinesthetic learners actively utilize all their senses when absorbing information, so taking notes during class is difficult to the point of self-defeating since they are writing but cannot supplement with listening and seeing as well. These learners also benefit from prepared notes, which they should say aloud as they write them out.
