Size: They come in sizes
0, 1, 2, 3, and
4 with 0 being the shortest and 4 being the longest.
Power: There are two powers,
M for mild-moderate hearing loss, and
P for moderate to severe hearing loss.
Your current receiver should specify the power and size on the silver part that goes in your ear. Sometimes it rubs off, if you are unsure you can always
send us a picture or check with your audiologist!
