comes with a couple grips to#3 noise cancel im a truck driver and people have a hard time hearing because of road noise but with these i find that i literally havent anyone complain "close the window" im happy#4 price u getting alot of bluetooth here for this price I bought this more for simple cleaning and light maintenance on both my Trek carbon fiber road bike and aluminum hybrid. The material is like spandex so I couldve went down one size. Además este modelo es muy bonitoSon muy fáciles de lavar, en el trabajo con un poco de alcohol o agua y en casa a la lavadora y otra vez como nuevas. Stylish but made of cheap plastic/rubber and very uncomfortable. The concept is great and I really hope they address these problems. I didnt pack it as its obviously going to bend. This product was definitely thicker than I expected. ) Sennheiser- Square shape, low profile, however not a lot of room for anything else in case. I wasnt expecting anything exciting, however those are just exceeding all expectations.
