No, my point is how the Airpods were designed. I have used ear plugs, earbuds, in ear headphones, in ear monitors or wahetever you want to call it for 30 years, Sony, Panasonic, Aiwa, Koss, iPod, AKG, Shure.. name them.. I have never had a problem with sealing, only how Air Pods are designed. The tip is pretty opened up and doesn't go in the ear canal so much.
No, because when they're really close to the ear canal, i can hear well, i can hear well how the high frecuencies are mudded, really lack of definition. A good seal, mostly improves the low frecuencies.
