Jabra Elite 75t Engineered to fit. Great calls and music, designed for compact comfort. We’re always on a mission to make your calls and music even better. So we scanned ears from different people from all around the world and ran them through our advanced algorithmic simulator to find the perfect size and shape. Then we added three separate sizes of EarGels™ to ensure a great fit for every ear. All our amazing tech crammed into a seriously compact design; these buds are a game changer.
