    I don't own one of these mics, but they are electret condenser mics and need "bias" power. You say your adaptor has tip and ring connected, but did you also connect the ground/shield?

    If yes, have you enabled the bias in your Flex radio's setup? Settings-->Radio Setup-->Phone/CW. The BIAS button should be blue/enabled.
