I have had them for quite a few years, 6-7, since I ride a naked bike without wind protection. However, since I don't take long trips, I don't use them often, but on every trip I've taken, they've saved me. The purpose is not to block out all noises but the harmful ones, while still allowing you to hear your surroundings, and the black ones do this very well. The red ones provide more sound insulation as they are intended for track and racing use according to the manufacturer. Personally, they suit me and I usually use the black ones to have better acoustics by isolating only the noise. The only flaw after all these years is that the small cord at the back, which helps you pull them out of your ear, broke, and now I find it extremely difficult to remove them from my ear. For fitting, they have an extra replacement arm that helps you wear them properly. Of course, they need frequent cleaning, either with the special cleaner that comes with them or with mild soap and water, to last long term. I haven't looked for better ones than these, but after all these years, they've been worth the money and I'm satisfied with them. They are also very comfortable. It's like wearing nothing once you get used to them.
