The Skullcandy Push Ultra are somewhat comfortable. Unlike many other wireless earbuds, they’re one-size-fits-all, with no selection of differently sized ear tips. Their bulky outer buds can cause some minor fatigue over extended listening sessions. However, due to their shallow, angled fit, the ear tips don’t exert much in the way of pressure, and their slightly flexible ear hooks should conform to a wide range of ear shapes and sizes.
