Well here's my 2 cents....
I too have the 50s unit. Zippy bought a pair and we split the cost between us. The update of firmware was way beyond me, but I have a good buddy (Pauly) that simply talked to himself and the unit while talking with me and 45 minutes later we were done. Haven't had any problems since, except Dan talking too much!!
Music; I've had good custom ear buds for years, this is better. Although I don't know how to turn it on or use it, it even has FM radio. (I put that in there for Gerry) In fact, I think these things would be awesome for skiing groups.
Taking breaks on the trail; I often feel guilty because Mike, Gerry, and Grubbie don't know what everybody is talking about when we stop. It's an extension of the discussion we were having while riding. One more thing. SandhillRider and I were leading a group last year, I think it was just the two of us with Sena's. We actually talked in a normal voice about the ride and scenery like we were in a car together.
I would not go back. If I get tired of the chatter, and that really depends on the day, I can just change to music while still listening to everybody I'm with.
