Good earplugs 1

As I am sensitive to noise and from time to time I like to go listen to high dB concerts, I bought these plugs that give me satisfaction. It is unobtrusive and effective. Of course they do not replace a good old helmet anti noise mitigation but is still good. Personally, I more or less downhill in my ears to the desired attenuation, can I not do with conventional earplugs foam or wax. I also used it under my helmet, it is a pleasure not to hear wind noise. That said I still hear surrounding traffic noise and my engine. So I'm not totally isolated which allows me to stay alert during my conduct ... Question comfort, that's okay. I readily recommend these same plugs if its price seems a little high.
