I'm starting to think about buying a headset and am basically overwhelmed with the amount of info out there so I'm asking which headset is best? I want a bluetooth headset that has good souns quality and connects easily. Most of my riding is solo so sound quality is important to me. I also want a headset that will work well when riding in groups or on occasion when I ride with a passenger. I'm leaning toward the Sene SMH10 now but the Interphone F5 looks appealing too. I'd even consider BMW's communication system if it works best. Thanks!
