I recently have added another small pocket BLUETOOTH speaker to my setup... These are called ILUV portable speakers from AMAZON. Thin enough to slip into your shirt pocket and still have great fidelity... I actually can have one ILUV pocket speaker in one shirt pocket monitoring some bluetooth audio channels and another ILUV portable speaker in my other shirt pocket monitoring a different bluetooth channel...

I really have several things coming from my POPUP Trailers being FM radio, Ham Radio, Police/Rescue Internet radio scanners, etc
Kinda hard to mix all of those through a single BLUETOOTH arrangement so having two or three audio channels going all the time is what works for me when I am sitting around the fire pit...
The only mixing problem is my Truck sync to my cellphone when I get close to the truck. It seems to take priority and that makes me have to reset a couple of mu bluetooth channels haha...
When I get into my truck and turn on the ignition key the truck sync immediately grabs my cell phone using BLUETOOTH. Then my BROADCASTIFY circuits need reset in order for me to also pass along some of these bluetooh channels to the master speaker setup I have inside the truck...
After a couple of resets I'm running down the road listening to all my bluetooth channels again...
