They work

Ho provato con 4 tipi di cuffie da diversi marchi ma nessuna era riuscita ad avere la leggerezza, il blocco dei rumori( secondo me più da 30db) la comodità e soprattutto la sensazione di non avere nessuna cuffia addosso durante 3,4 o 5 ore di lavoro continuo, voglio dire che non danno fastidio per niente, assolutamente me ne comprerò un'altra,tutti i 4 tipi che in precedenza ho provato costavano tra tra 2 o 4 volte di più ovviamente sono più belle da vedere ma il problema non è la bellezza,comunque soddisfatto del Aquisto ad un prezzo molto economico...il mio voto per cuesta cuffia 110 e Lode.

I bought myself a really noisy Stihl petrol strimmer recently and the first time I used it I thought I was going to need a paracetamol the size of Wales to get rid of my pounding headache. I could barely hear anything after using it for about 2 hours. I got serious tinnitus, and had to lie down with the pain in my head.So I got these. Putting them on, the world goes very muted. They cut down the bass-y noise of engines really well, but you can still hear higher-pitched sounds a little better, like people talking to you. They're still very muted, but with the strimmer running, I can almost make out what someone's shouting at me, which is far better than if I wasn't wearing them.They're comfortable and adjustable (to a degree), and they look pretty good too. If you're strimming, grass bits fly everywhere, so it's important that these have a nice glossy plastic finish, easy to wipe down after tackling a large garden.Pretty good value for money too. I've paid more for ear defenders before, and I'd give these a 4 star rating for blocking noise compared to seriously high-end ear defenders. But then, these are a fifth of the price of high-end ear defenders.If you really want to cut the noise level to zero, pop in a set of ear plugs as well as wearing these. You see builders doing this on site all the time, as it's a great way of completely nullifying pneumatic drill noise.
