This small hearing aid can be worn in either ear and fits snugly in the ear canal. It is a color close to skin tone, so it is inconspicuous and you don't have to worry about others noticing. Four different sizes of ear pads (S, M, L, LL) are included, so you can choose the one that fits your ear size. It also has a volume control function that allows you to change the volume while wearing it, so you can listen at the best volume for the place and time. The volume can be adjusted to your preferred level with the dial, and when not in use, you can easily turn it OFF by minimizing the volume knob. It comes with a dedicated storage case, so you don't have to worry about losing it when you go out. It can be used indoors and outdoors, such as at home, school, or the office.
