I love the feet protectors and the fact that it mounts on the wheel. The front one is slightly over the sunroof though. WiFi etc. Klangliche Unterschiede ob am Ladegerät oder Akku gibt es nicht. Works just as well, too! Sound quality is roughly in-line with what youd expect. This 7 fits like a 6 I used it with no top Rack on Suv. ANYHOW! ? Buen peso ligero con 238 gramos, aunque no es el más ligero, ese premio es para los Plantronics con 189 gramos.
