Great sound. Built tough!
This is a well crafted microphone solid and built like a tank. Its ruggedness makes it great to use as a handheld live performance vocal mic, which is what I mostly use it for. Although not exactly lightweight, the M3 is not a burden to hold - on the contrary it feels well balanced and solid in the hand.
The sound is crisp, yet mellow. I have used a couple of other proular live vocal mic brands, but I think the R?E M3 produces superior sound.
It's great having the choice of Phantom or battery power, and the on-mic selectable 80hz high pass filter switch is a good inclusion, as is the -10dB and -20dB pad. I have a fair amount of sibilance in my voice, but find the included foam windshield greatly reduces the s's without making the sound muddy.
I was impressed enough with the M3 to buy a second one! With the quality of this microphone, it's easy to see why R?E are confident to offer a free 10 year extended warranty option (via online registration).
