iFlops Frog Universal Headphones for Kids Fully Adjustable Multi Purpose

I don't know if I just got a defective pair, but sometimes only one speaker works and it annoys my three year old to no end. I have to play with the cord where it plugs in to the player to get both speakers to work. Also, took me a while to figure out how to adjust them to fit my kids' heads. The top strap just stretches out when you pull apart and you push it back together when you want it smaller (this takes a little muscle to do). It's hard to tell because of the fabric where it actually adjusts. Anyway, very cute, I just wish both speakers worked all the time.
