I've bought this Ohenstöpsel as hearing protection to sleep.
The stopper fit comfortable and close well off, breathing sounds from a Mitschläfer in bed are covered fully coming.
However, the "Style / root" of the "fir tree" is the way the plug looks very hard, and painful, less the lie.
Bin in 2 nights woke up with pain on the side where I am located.
An ex-girlfriend of mine schläuft exclusively on his stomach or on her back where the head is straight, these risers can I recommend earplugs. I sleep unfortunately side and was in pain by about tough style.
Nevertheless:
The ear plugs fit perfectly, are super easy, well-made, and do exactly what they want, and the good.
To fall asleep, they have helped me super, my girlfriend had not perceived before me, at least technically breath.
