Plugs very effective in my case. I hyperacusis (too acute hearing) that spoils my life and causes me constant headaches. Since I wear these caps, goodbye migraines and associated bad mood! They are comfortable to wear and fit perfectly in place, even if it takes a little practice to put them on. The sound is reduced but not stifled, we can clearly hear the TV and conversations but little noise. (Kettle, microwave, small games console ...) However, they must measure his ear and take the appropriate size for comfort. The small central plug for nothing heard is very effective, and convenient cord! The only slight downside I found him is that if you walk a little faster, we hear air whistling in the central conduit. And for those who fear him, outside noises are reduced as much as those of our body are increased! But it is a great product that I recommend highly !!!
