Good product, before this I had earplugs with speakers sticking out (universal) This is so much better, no pressure points and also all the benefits of a "normal" set of otoplastics. I say do it.

The porto earphones take some getting used to, at first the attenuation was too heavy. This has been adequately adjusted.

Fine walkie-talkie earphones, Audinc comes to us every six months to fit new colleagues. Would recommend it to anyone who makes them long days, so much better than the universal ones.

Have used the porto protect for a season now, ideal. 1 porto earpiece with protection on the left and a loose protector on the right. Have already sent several people through.

Use the porto without protection, ambient noise is thus the same. Much better than the universal where I have irritation after a few hours. Had first gone for the hard one, have now ordered a loose soft one . I wonder how this one compares
