A:Answer Hey there! This is a great gift, however I would say that I would be cautious if they are young kids. The glasses are sturdy, well made and the quality is great allowing one to change the lenses.i love that one can pay attention to surroundings without blocking out hearing their tunes.
The Alto fits in two sizes to perhaps the small is a good option if the kids have smaller faces. You are one cool parent for getting these, they do cost a pretty penny but pair well with an Apple phone.
Hope that helps!
