Excuse my ignorance, but for the purpose of plugging a mic into an arranger keyboard's dedicated mic input, are there any advantages to having a condenser mic as opposed to a cardioid mic? Audio-technica makes a cardioid condenser headset and a condenser headset mic. I know that with a condenser mic, you would need a battery pack or a phantom power adapter. Having one of these (the Crown CM-311A comes with a battery pack for example) what's the difference in sound between this mic and a non-condenser mic?

Thank you!
