My iMac doesn't recognize bluetooth headphones
You have not provided ANY useful information. What iMac, what version of OS X, what headphones, etc.....
All we can recommend is for you at this point is to verify BT is turned on and check the manufacturer of the headphones and see if they support the version of OS X installed on the computer.
Gosh thanks! Yes, bluetooth is turned on (what an ***!), and yes the iMac is plugged in and running Yosemite 10.10.5

Have you verified with the headset developer that the headsets support Yosemite 10.10.5? BTW, please refrain from the rude replies. We cannot tell what you have done, what system you have or anything unless you write a description that paints a clear picture, that was all I was attempting to communicate. As may have noted, I asked the moderators to remove the rude comments.
