Ordered to machine noise in a factory building the earplugs restrict me. The temple itself sits neatly in the ears and is initially quite comfortable. After some time, you already noted, however, the pressure on / in the ear. Thus, the comfort is limited after a while. But keeps everything under. Therefore recommended yet. The attenuation of the background noise is carried out reliably. A bit more efficiently, it could yet be - one would have in the model even more pressure on the ear in buying so take a "clean finish" is ensured by ear.
