Sounds like you are spot on with that call.Just my two cents on bt i run 20 sena they are fine with just two folks but anymore than that your not going to like them. I think someone with cardo will chime in but i believe that would be the route to go. .Did you try beemer bone yard for a voice 2 setup no one wants them any more so might be cheap. good luck
I think further effort invested into the VOICE II is wasted. The main reason is that the VOICE II and BMW headsets have never been that great even when brand new. They were far inferior to the Clarion units on my Kawasaki Voyager.
Now, it may be that I have an intercom that was defective from the factory and a good used unit might work like my old Kawasaki system, but I am not willing to take that bet given both the cost of a VOICE II (I saw one advertised used for $500 on ebay!!) and the 3 hours or so of labor required to remove the tupperware to replace it.
I have narrowed my search to three options in order of current preference:
1. The current top of my list is the Cardo Freecom 4+. It has all of the features I likely need and looks to be one of the trimmest designs. The main thing it lacks is DMC, but I am really on the fence as to whether I need that. I donít ride in large groups and likely need to intercom with only one other bike a couple times a year (use CB for that now). If the BT doesnít work well enough for the bike-to-bike CB replacement function, a cell phone call will work most of the time, except in Newfoundland and a few places with poor cell coverage. And hand signals arenít bad with just two bikes in a remote location that has little traffic. Two of these units are $450.
2. My second choice is the Cardo Packtalk Slim. It is more expensive and only fits certain helmets and I need to check to see if it fits either of my helmet sets. If it fits my current helmets, It is a nice design as it separates the battery and such from the controls allowing thinner external controls. It also has DMC for reliable bike-to-bike communication which would be a great CB replacement. The main downside is the $600 or so cost for a pair and potentially the need to buy different helmets in order to mount this product. I have also read that these mesh communicators (whether Cardo DMC or Sena 30k mesh) tend to consume battery much faster than the BT only sets as the mesh is constantly in communication to check for the addition and departure of other nodes (headsets). And, based on my rental experience with Sena units, battery life is an issue for me as I had fully charged batteries expire on me in 2 of the 15 days we rode in Ireland and England last fall. I know that the Cardo units can be charged while riding, but the Sena 20S can not.
3. If I have to buy new helmets as discussed above, then I am quite interested in the Sena Momentum INC. However, now we are talking real money at about $1100 for a set of helmets. The pros are that this helmet is apparently very quiet, so much so that ear plugs are no longer needed and the BT integration is very nice with nearly flush mounted controls and charging port. And the battery life is claimed to be 20 hours which would give reserve for all but an Iron Butt ride. The downside is that if the helmet is damaged, you lose a perfectly good headset as apparently there is no easy way to move the electronics to a new helmet.
So, still thinking about DMC/mesh vs. BT only, but leaning towards BT only as I just donít see a need to use the mesh more than once or twice a year and a cell call probably would suffice in 80% of those use cases. So, I probably will go with the Freecom 4+ as I like its design better than the Sena 20s Evo and I like that Cardo is guaranteed waterproof and can be charged while riding where Sena is not and can not. We rode in a lot of rain in Ireland and we had a few days with a lot of disconnects between the Sena and my GPS. I did not know at that time that the Senaís were not truly waterproof (just water resistant, whatever that really means) and I wonder in retrospect if I was having issues with water in the units.
