It simply solved my problems with neighbours’ noises when I’m trying to sleep. They are comfortable and you can still hear some more loud and close noises, like an alarm clock. It’s perfect and I’m very happy with them.
The original package contains two sizes plugs: Small & medium. Medium was still too small for my ears. The company provided size large, free of charge, and the plugs now fit perfectly. And they work perfectly. Still sounds can be heard, but they’re muffled, and seem far away. The plugs were – like the other plugs – white/translucent. After a short time they became yellow/translucent. It doesn’t seem to influence the plasticity, but they look dirty. That’s not how it should be, I think. I suppose those plugs came from an early batch, produced from different material. The original plugs from the package are still in perfect white/translucent shape. Hence my four stars, instead of five.
I am sorry to say that I don’t believe the specs. On the front of the Sleep model 25 dB is claimed. On the back of the package it says 16 dB. But compared to low cost ear plugs it performs bad. 6 dB at the most.
Sales Dynamic Ear –
The 25dB mention on the front is an average dampening for customers to have an idea how much it will be. The actual attenuation which is certified is indicated on the back on the product. We understand this might be a bit confusing.
6dB is really strange, this low dampening could suggest that the tips used might be either to big or to small for the hearing canal to be fully sealed when inserting the earplugs. The package contains medium and large tips, have you tried swapping the tips? If you would need Small or X-Large tips please let me know as we can provide these for free and should help with creating a good seal.
A bad seal between the eartip and ear canal will most likely happen if the eartips are to small or big.
Hope this helps.

Nice fitting earplugs. Comfortable fit. Filters out all disturbing noise. Used to wake up with earplugs in the bed or on the floor. These plugs stay in till I remove them in the morning.

Comfortable earplug – Nice service that you get 2 sizes. Not really blocking the snoring noises. But better than the previous ones I had.
