After doing extensive research, I bought a Pro-Ears Ultra Passive Series headset for my 18 month daughter. I needed ear protection for her as she isn't yet comfortable in louder situation, like in a crowded room with ambient adult talking noise, or other crowded situations.
Virtually all of the headsets designed for babies appear of low quality and also appear like they could easily fall apart at any time. That's why I looked into getting an actual adult version if I could find one that would accomodate small sized people. This set of pro-ears fits her just fine, and of course, adjusts to an adult very easily also. We are very pleased and this will allow us to introduce our daughter to more new situations faster than we otherwise would have been able to.
Pros: Size, fit, comfort
