Sena will talk to just about anything. Senna blue tooth works well over a reasonable distance, and battery life is excellent.
Blue tooth V Wired..
Wired intercom doenst need power, but on its own cant talk bike to bike. You are wired to the bike, could be a problem in an off, and its a connection that could break. When you walk away from bike, you lose connection to UHF, Music, Phone and passenger.
Bluetooth :- depending on brand, battery life can be a problem, (constant playing of music may affect battery life, I dont do that so dont know for sure) quite a few have poor high speed/noisy environment reception. A good bluetooth, gives excellent sound, and some can talk to up to 7 other headsets at the same time. Get off the bike with helmet on, and you can still talk to passenger and other paired headsets, you could even hear whats happening on the UHF (if power is on) and use your phone.
