A:Answer Corrected answer. The MEE instructions show a limit of 2 bluetooth headphones. After the 1st headphone is "paired" by pushing button "A", a second bluetooth headphone will be paired by pushing button "B". Included in the packaging with the transmitter are a AC power adapter, a micro-USB power cable for recharging the lithium battery as well as a 3.5mm audio cable, digital optical, and RCA cables. It appears from the wiring diagram, you can choose to power the transmitter by connecting the USB power cable to your laptop while using or rely solely upon the battery. I have found the battery life excellent. Can you connect to an iPhone... if it has a 3.5mm phone jack, it should work.
