not another usb cable, i was hoping for the standing 3.5mm cableWould you accept one that is powered by your phone's USB port/cable (while charging from it, thus draining the phone's battery to do so) to continue working over bluetooth?
If you answer yes, I still don't have a suggestion but this might open up the possibilities because some can be used while recharging but others can't. It just seems like the more popular possibility than bluetooth headphones which also have an analog audio input socket.
