Dont waste your money! Diciamo che svolgono comunque bene la loro funzione di attenuazione, ma mi sarei aspettato di più. but they are nice and light! Some people either got some kids version, from the other reviews Inhave seen,or didnt realize that the wire "sticks" going from the band into the earmuffs can be extended out to give the whole thing a bigger fit. So, not a clean and smooth setup process and needs some tinkering. My 2 sons are sharing the room with each other and my youngest son usually sleeps early, but my older son would like to watch TV until late at night. So that is nice for a $20 price difference. they are ok but not more. The Megaboom 3 is a rugged, relatively waterproof speaker with great sound & ability to play fairly loud. I already installed two standing fixtures and those filled up fast, both together hold less items then this one collapsed EXPANDABLE (yes it has two heights, shortest is around 5’5” tallest is 5’10” roughly and it has a extending top rack)The casters have locks on two but I can’t seem to get them to work.
