It seems like most everyone, even young children, have portable mp3 players of some sort. The big concern with the in-ear buds that come with most of these players is hearing damage. Ultimate Ears is making a line of earbuds for children that can help prevent hearing damage. The LoudEnough earbuds uses an “energy dissipating device before the speaker” that reduces music levels by as much as 40%, with no loss of sound quality. LoudEnough earbuds come with three sizes of ear tips, two sets of each size. The ear tips are sized from extra-small (for children six and over), small, and medium – so even adults can use them. They come in plum, blueberry, and mint and have a color-coordinated case for storage. They are about $40 from LoudEnough.
