A perennial problem with in the ear hearing aids is ingress of wax, skin flakes and other debris found in the average ear canal. This can have a detrimental effect on the performance of your expensively purchased hearing aids ranging from slight dullness to fully blown wooliness to no sound output at all. With the advent of better waxguards hearing aid users can look forward to increased reliablity and less down-time because the newer wax traps are easy for anyone, even with limited dexterity to change in a few seconds.
