The sound of e945 is nothing short of awesome. Comparing to the mainstream models like SM-58, this mic has a lot more clarity and detail. Moreover, e945 has less coloration and can sound great without relying much on EQ. Highs and lows both sound crystal clear. If you were considering an upgrade from SM58, then this mic would be the best candidate as it easily beats it in every aspect. Gain before feedback, noise reduction, detail and clarity, frequency response, etc.
