Great product for when overstimulation from noise becomes too much.

Definitely recommend it ! Worldly difference

I had been using custom made earplugs at events (carnival, festival ect) for years. As I got older (55+) I noticed that it became increasingly difficult tounderstand other people at an event. When my earplugs needed replacement, I chose the Authentic type because they have a flat attenuation curve. My experience is that I can understand other people better at an event, while the rest of the sound is sufficiently muffled.Read more

A year ago I bought custom sleeves for my Shure SE 215. The fitting itself (at Sloterdijk) was fast, smooth and the advice was very pleasant. In house within the agreed delivery time, very good.

After about a year of use, I am still very satisfied. They still fit like a glove, don't leak and go in and out easily. Only minor concern is that the sleeves are relatively loose from the Shure monitor itself.

Because of this, the sleeves may well fall off the monitors. I would definitely recommend this product!

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.
