Review on Joymiso Tangle-Free Earbuds for Small Ears & Women with Case - Comfortable Lightweight In-Ear Headphones, Flat Cable Earphones with Mic & Volume Control for Cell Phone Laptop (Blue) by Erin Nichols

The sound is ok but even the smallest headphones didn't hold up well for a 5 year old. Fits a little better for an almost 7 year old but still problematic, especially prone to falling out when moving her head. We ended up using earmuffs over it. They're certainly better than the other options I've tried, but I wouldn't recommend them unless you really need them to stay in a small child's ears.
