pretty easy to run the speaker and mic for each side
They synced no problem first try. They updated to the newest software from phone no problem too.Charge lasts a long time. They are not fun to sync however. Every time we go we are uncertain on the sync and it takes a couple tries. Once sync'd they usually stay that way, but not always. More range would be great, but I can't imagine riding without them. On ATV's they are even more helpful as the speed and separation is not as big. Love mine.
