I just bought a Jabra BT8010 and was disappointed to find that it does not combine left and right stereo channels when the second earpiece is disconnected. I already have several A2DP solutions that give me true stereo, so I don't need another and I need both channels over mono to do my job while using these.
I popped the speaker off the second earpiece and it's clear that there are only two wires going to the entire unit. It comes right from the main earpiece directly to the secondary one's speaker. To connect, it uses one of those mini USB ports with 8 pins and not the more widely used mini USB type, so I assume that some of the extra pins are reserved for audio... at least I hope so. If the same pins are used for power or data (the same port is used for charging or firmware upgrading and phonebook management through USB), I probably can't just wire it up permanently. That's cool though, because I'm sure I can work out a loop-back connector if that turns out to be the case (I don't know how to check continuity on such a tiny connector).
My REAL question is this: If I just splice them to the same speaker, will the volume be twice as loud? Should I use a resistor or something to lower it? If so, how can I tell the proper ohmage?
