I have a headset electret condenser mic that has a low frequency response.
Other than changing the element is there a means of getting a higher
frequency response?


Are you saying that the frequency response is poor, as in it is unable to
respond to high frequencies such as speech sibilants ? If so, that is very
unusual, as in general, the frequency response of an electret mic is very
good - certainly more than adequate for speech, and in most cases, good
enough for pretty much anything short of professional recording. A quick
look at the specifications of a few shows them to be good to at least 16kHz.
Has the response always been poor ? Are you sure that the problem is not
something much more fundamental, such as the small hole where sound gets
into the mic, being stuffed up with fluff or other clag ? Or are you maybe
feeding it into an input with entirely the wrong sensitivity / impedance ?
Does the insert get it's supply from an internal battery, or should it be
fed with a phantom supply from the equipment that it's plugged into ? If so,
is the equipment providing such a supply ? Not quite the easy question that
you were supposing perhaps ... ??
