So my earbuds are falling out and I am constantly adjusting them while I run. Its frustrating because I am trying to concentrate on my form and breathing but instead I am bothering with my music. Is there something different I can try? I don't know much about headphones or earbuds. I thought maybe that headphones would be better than earbuds, is there anything out there that is not bulky? I am using an iPod and I have phillips earbuds with squishy inserts I have used each size its comes with... the smalls seem to work the best but I am still constantly pushing them back in my ear. Does the cord of the earbuds cause them to fall out? How can I fix that?
