Fusion includes multiple eartip sizes so you can find the best fit.
Choose the smallest size that still feels secure and provides a good seal. If the eartip is too small, the hearing aid may whistle or feel loose. If it is too large, it may feel uncomfortable.
If you are between sizes, try both and keep the one that feels stable and comfortable during normal use.
