I took them on the 500 mile 'Camino de Santiago' through Spain and then continued to use them when I got home about years ago came I lost them and then bought another pair. I will keep buying them until I or the company is dead. I gave it a 4/5 for comfort because they always sit weird in my ears. It's comfortable, but I notice that the sound quality degrades at times, so I have to squeeze it around my ear. They come with three ports, but hey, they're not the best.
