Achieving an optimal seal between the ear canal and the earbud is crucial for sound quality. Many individuals, especially those with smaller ears, find that the standard sets of S/M/L tips included with most earbuds do not provide an ideal fit. Consequently, the sonic benefits are compromised, and discomfort may arise. While custom-fit tips offer a solution, there are several factors that have limited their adoption in the audio industry.
Cost is one significant factor, with no pricing details available yet for the Sennheiser/GEERS offering. Similar services, such as Avery, charge approximately $163, which is a significant investment on top of the initial earphone purchase. Functionality is another consideration, as custom tips may impact features like case compatibility and on-ear controls such as noise cancellation and play/pause taps.
