Hey guys. My workplace has office phones which use a rear analog RJ9 port for separate headset connections. Some months back, I got tired of shoulder-pinching, and decided to grab one of these adapters --- which converts the RJ9 to dual 3.5mm stereo connections --- and a cheapo headset. It works fine; exactly as expected.
I would now like to upgrade to a wireless headset. Apparently anything with a native RJ9 connection is over $200, uses only a single earpiece, and/or has crap ergonomics. I'd like to use my own bluetooth headset. And that's where the problem lies....
Apparently there is no such thing as a bluetooth-to-analog adapter with simultanous transmitting/receiving, such as you would use with a headset. Those which would appear to do this are all made for use in cars, and only accept mic input from a small microphone built into the device itself. None will accept mic transmission through the bluetooth connection (as you would with a headset), nor do they accept input via analog (for transmission back to the headset). Everything else is made for home stereos, and only works in one direction.
Am I just searching using the wrong terms? Do I have some sort of brain fog or early-onset dementia? I had no anticipation that it would be this difficult.
