Stumbled across the thread about replacing the battery in the f5mc the other day and got all excited since mine hasn't charged for crap in a while. Order up a battery, and now I can't find the thing. Thought it was in my jacket but no matter how many times I check the pockets its just not there. Anyway, onto the whole point of this, being a little fed up with the F3whatever I finished out last season with I started looking at replacements. Maybe something thin like the Sena 10r. Can't say I've ever really noticed the interphone on the side of the helmet but whatever, thin is cool right? Looking around I stumbled across a thread here about bluetooth headphones. Tech is getting pretty good these days with those, they seem to last a while, or at least long enough that I'll need a break long enough to recharge them a bit before they die. Heck you can even get them with noise cancelling... though I'm not sure that would be the best idea really. So, question is, has anyone made the switch one way or another? I've literally never used the communicator for between bikes, the KTM has handlebar controls for music anyway, and I don't have a microphone mounted in the current lid as it is, Bell Mwhatever adventure if it matters. That being said, having the thing on the helmet is convenient. I did the headphone thing before and it can get old. But when I'm doing highway I'll use ear plugs anyway so is it really any worse?
