Perfect companion of my children 5 and 3 years on any football match together, etc. The sound is attenuated enough to reassure and protect their eardrums, but they always hear what they are told. Tested including a performance of circus and a football stadium with> 100 dB at the entrance of the players; my kids (yet sensitive to noise) never stumbled. Attention however to put it straight as not to catch their small ears. Otherwise easy adjustment and minimal space when folded on itself. I recommend it.
