I tested loud background music playing on another floor of my house and also tested them outside near a school with kids being dismissed and cars driving by and wind noise. Its easy to use and fits perfectly on the handlebars. Bought these last summer (that she wore A LOT but they still look great and can be handed down) and now rebuying for this season. She can easily take them on/off by herself. ? Calidad de sonido espectacular. Feels as though you will break the cover when removing. I?d definitely buy more if they had other patterns with black backgrounds. Real easy to assemble, but like my title, dont push too hard as the connectors can snap, but there are some spares. And I like that it doesn?t bang the door as you as opening and closing it. I put the tools that I would use in the slots and they all fit perfect.
