Headphone Recommendations

I use headphones with my students in the computer lab for Kid Pix, Scratch, web conferencing and the internet. My students range in ages from 5 - 12. I can't seem to find headphones that are small and very durable for students. It seems that every day one of the cords of the headphones is wrapped around a computer chair or tangled or the ear circles break off. Any suggestions for really durable, but not that big headphones-- ideally with short cords from the computer to the headphone?
Thanks in advance!
