There are 3 main types of earbud shapes, single, double, and triple flange ear tips. Out of the three, the single flange tip is more comfortable for most people and delivers great audio. Double and triple flange ear tips can be harder to fit and can be uncomfortable for some. You can get even better quality audio with these if you find the correct tip. There are also flat-shaped ear tips for those who hate in-ear earbuds. These are more comfortable as they don’t fit inside the ear canal. They provide adequate and balanced audio. In the end, the earbud shape you choose should depend on how comfortable they are. You can get decent audio from all shapes, so give them a try and find the ones that will not affect your experience.
