I was able to pair my R-15PM's to my iMac Bluetooth. It worked and I played music from iMac through R-15PM's. Next day was unable to play music through speakers even though computer said "connected" by Bluetooth. I unpaired them, restarted computer, shut speakers on and off several times, and still unable to pair them back using instructions for how to pair speakers to device. WTF am I supposed to do? :)
