I came across this QYT Wireless Bluetooth Microphone.
It does not have a DTMF keypad, however, it is rechargeable and equipped with a 1400mAh battery. It comes with a receiver/transmitter that plugs in to your QYT KT-7900D or KT-8900D radios. The range is 10m and the stated standby time is “About one week”.
Not sure if this could potentially work with other radios. It is a fact though, that at least the older QYT KT-8900 radio uses a Kenwood type microphone and some people have successfully used a Kenwood microphone with the radio. I am guessing that it should work with other radios that are Kenwood or Kenwood compatible. The microphone on these radios is connected with an RJ-45 plug.
I can certainly see a use for this. It is very helpful to have one less cable to deal with, especially if you are mobile. Although you would still have yet another thing that would need charging from time to time.
You can get it here.
