They will work for now. My son and I loved them.
Fits my Kindergartner well. I like that it is adjustable. While at school it may have became a little loose and a teacher tried to tie a knot in it. We got it undone and we can listen and tighten it again. So it may come loose after a lot of activity. After school he told me that as soon as he got on the bus he was staring at it and he told others about the story of it. It helped us both while he attended his first day of school but I think we will continue wearing them for awhile. I may look for a sturdier design, but these will definitely do for now.
