Earasers Musicians HiFi Earplugs, 31dB Peak (NRR 16 | Max Filter); Small
Most people already know if they have small ears due to their experience with other earbuds. Don't worry, there is some definite overlap in the sizes. If you guess wrong, you can always exchange them within 30 days. Or, they make great fishing lures.
If you think you have tight ear canals, then go for the small. If you have been practicing ear canal stretching just for this moment, and you are sure your ears can park a mini-van and a drive-in speaker on the side (remember those), then you might belong to our 1% LARGE club. We rarely see them, but we know you are out there. Funny thing is, the size of the external ear (the pinnae if you keep a dictionary handy) rarely has anything to do with the size of the opening where these bad boyz go. So, don't look at the outside. Take a look at our sizing pictures, take a picture of your own ear, you know where the oval shadow shows up (and not where you keep those spare potatoes) and have someone help you determine what size you really are. It's great fun for the whole family, and the bridge club too!
