I bought a pair of BT stereo headphones and paired them with my receiver. They work great once they are paired, however if the receiver goes into "sleep" mode or the headphones are shut off for a length of time, they won't "re-sync." The bluetooth status on the receiver says "unpaired." The only way I've found to get around this is to unpair and then re-pair the headphones with the receiver each time. Has anybody else experienced this???
