Tienen buen sonido aún en Bluetooth pero mejora aún más con el jack. not cheap Velcro and they are not falling off until you take them off to put your thuele back on. But not all three at once. On the other hand, my wifes bike has the typical set up and if you want to angle it down, just give it a nudge, or side mount it adjust it. AND RED! We needed this adapter to complete an installation, and it did exactly what it is supposed to do. I think I probably charge every three days. They are excellent quality and look much higher end than the price suggests. Tienen mucho impacto en la pisada porque la suela es muy delgada. I have a 2004 Rodeo SUV with a roof rack that is about 5 6" off the ground.
