Noise Isolating Fit With Two Ear Gel Sizes
The Jib's round silicone buds sit inside the ear canal, and the box includes small and medium ear gels so you can choose the one that seals best. The seal does two jobs: it keeps outside noise down, and it holds in low-frequency sound, which is why a well-fitted budget earbud sounds fuller than a loose one. This is passive noise isolation rather than active noise cancelling, and in practice it keeps out a fair amount of sound without silencing it. Comfort is one of the most praised points, with people wearing them for hours without soreness, and the small gels suit smaller ears. Fit is still mixed overall: for some the buds work loose, and there is no large gel in the box for bigger ear canals. If a medium gel slips, pushing it slightly deeper with a small twist often helps it seal.
