Besides "bone conduction", another source of delay may be the DSP processing inside the KX3 itself. This can wreak havoc with your CW side tone for example if you add an aftermarket audio DSP to a radio. Elecraft have obviously taken steps to make sure that the KX3 doesn't have an issue with CW sidetone, but in the case of voice where they are doing audio equalisation for example, they may be using some long FIR filters that introduce a bit of delay. Can't say I've really noticed, because I rarely use the KX3 on fone, and never with monitor on fone.
