Today I have used them for the first time and I'm very happy with it. No eternal Weichgeknete and especially not bonded hands! These plugs are made of foam. One has only to roll, insert it into the ear canal and keep pressed for a short time.
The wearing comfort is basically okay. But after a few hours of wear they begin to push a little uncomfortable (perhaps they are a bit too big for me). But this was no different with the ear plugs-plugs. I would compare the pressure with the hours of wearing strap headphones - just inside instead of the outside.
I have the earplugs bought mainly because I need rest for learning and lately the strong chatter and clamor of our budgies could stand not as good (at least four of them - probably the Abi-stress .. actually it does not bother me so - )). With the plugs you can still hear it (of course), but it is not more so pervasive and so annoying. More can be MMN of earplugs and do not expect.
In short: buy recommendation. :-)
