Tireless Tweaking for Broad-reaching Comfort
No matter how good their performance might be, users are likely to avoid using earphones that are uncomfortable. As the Galaxy Buds Live were developed to accompany users throughout their days, a lot of effort was put into ensuring they were as comfortable
as possible. “During development, 80 earbud RPs (Rapid Prototypes) were developed to check the product’s optimal size, shape and specifications. We prepared a lot of RPs since even the tiniest difference in form could lead to huge changes
in comfortability levels,” said designer Youngsang Jang.
The human ear comes in a wide variety of shapes and sizes, thus finding a fit that satisfies all presents a significant challenge. And this was especially true in the case of the Galaxy Buds Live, which underwent meticulous user testing to ensure they
provided a comfortable fit to a broad range of users, regardless of the shape and size of their ears. Designer Joonha Kim elaborated on the testing process, saying that, “At first, subjects used the earbuds for a short period of time
and received their feedback on various points. We knew we couldn’t satisfy all the subjects, but we developed the design so as to satisfy as many people as possible. Then, we performed tests in which the subjects used the earbuds for
longer period, and tested in a situation with big movements to refine the shape and create a comfortable earbud.”
“Setting the standard for comfortability was the most difficult part,” added Choi, who also worked on the testing. “When eight out of 10 subjects responded by saying that the earbuds were comfortable, and only two rated them as uncomfortable,
we had to ensure we made modifications that satisfied those two subjects without compromising the satisfaction of the other eight. In order to make a comfortable product for as many users as possible, we tested on around 2000 subjects.”
