Here is my review of the EV RE20 mic. It is now my go-to vocal mic. So that's sort of a spoiler about what I think of this fabulous :-).
So I just finished testing out the Electro-Voice RE20 Dynamic Microphone, another fabulous vocal mic that I've been wanting to get my hands on for a long time. The other large diaphragm dynamic was the Shure SM7B, which I reviewed last week).
Like the SM7, the EV RE20 is an end-address (you talk into the end and not the side, as with most large diaphragm condensers) dynamic mic found most often in use by radio DJs and other broadcasters. Also like the SM7B, the EV RE20 has a "cardioid" pickup pattern, which means it is most sensitive to what is directly in front of it, while rejecting sound from the rear. If you want to review mic pickup patterns, see my article Directional and Omnidirectional Microphones – What Are They Good For?
[Ken explains - in probably a few more paragraphs than necessary - the answer to the above question. If you don't care, and would rather just skip to the stuff about how the mic sounded, click here:)]
Yes, typically you'd be told to use a large diaphragm condenser microphone (LDC) for vocal recording. That's because those mics are super sensitive and can pick up the nuances of a voice really well. Also, compared to your average dynamic microphones like the standard computer mics, headsets and ice-cream cone shaped mics you see on stage for live performances, you can get better vocal quality in a recording at a really decent price. Entry-level LDCs often cost under 100 bucks.
For studio recording, dynamic mics are normally used only for things like drums or loud electric guitar amps. Dynamic mics are generally less sensitive than condenser mics. And while there are exceptions of course, vocals are almost never recorded in the studio with dynamic mics. Condenser mics are widely regarded as the mics of choice of the voice recording world.
However, because LDCs are so sensitive, they are infamous for being TOO sensitive to plosive sounds - the little blasts of air that come out of our mouths when we say words with Ps (and sometimes Bs) in them. This results in unpleasant low-frequency/bassy "splats" in the recording. We usually call these "p-pops."
This makes it basically mandatory to use something called a pop-filter or a pop screen when recording vocals with an LDC mic. These are those round things with fabric (typically) stretched around them - sometimes they're made of metal - that are placed between the mouth and the microphone. Pop filters help to prevent p-pops, but they do not eliminate them for most people. Personally, I end up having to edit out every plosive I utter in a vocal recording - even when I DO use a pop filter - which can take a really long time.
Dynamic mics, on the other hand, are often less sensitive. So they can also be better at preventing p-pops from getting onto your vocal recordings. The problem is that most dynamic mis just don't sound as good when recording in the studio.
But there ARE some dynamic mics that DO sound great on vocals. They just aren't quite as affordable as a lot of decent LDCs. The kinds of dynamic mics I'm talking about are the ones typically used by radio DJs and other broadcasters. The Electro-Voice RE20 dynamic microphone is the industry standard dynamic vocal mic.
A few other specs include what's called a "Variable-D" design, which reduces proximity effect. That's when a mic sounds deeper (lower frequencies) the closer you get your mouth to the mic. Variable-D is a proprietary bit of design foo that limits that.
One word - Awesome. I said the Shure SM7B (another broadcast quality dynamic mic) sounded great on my voice. And it does. But the RE20 sounds better. I was pleasantly surprised.
But here is the best part. Even without a pop filter, the p-pop/plosive problem was almost non-existent! That was my one quibble with the SM7B. Though it was not as sensitive to plosives as my Rode NT2-A (an LDC mic), there were still quite a lot of p-pops with the SM7.
But the RE20 really shines in this very specific, but very important matter. In the RE20 audio recording below, there were a couple of p-pops still. I recorded all samples with my mouth 3 inches away from the mic so they could be fairly compared. But when I backed my mouth away just another inch or two, the p-pops were gone.
The lack of p-pops in the RE20 recordings means saving a ton of time when producing any vocal recording, since I won't have to painstakingly scrub through and edit just about every word with a "P" in it. Given the amount of time I normally spend doing plosive-hunting, this is a real game changer for me!
There are a couple of reasons for the better plosive (p-pop) response. One is the Variable-D design I mentioned above. In addition to that, the mic has a heavy duty internal pop filter.
Whether one mic "sounds better" than another can often be quite subjective. And truth be told, a mic that sounds fabulous on one person's voice can sound bad on someone else's voice. And honestly, all three of these mics are very good!
So with that in mind - after listening to my voice in the RE20, and then comparing the audio of the same text recorded with 2 other mics (my usual Rode NT2-A and the Shure SM7B), I felt that my voice sounded better with the RE20.
But for a sanity check, I asked my wife - the lovely and talented Lisa Theriot - to come up and do a "blind" (deaf?) listening test. She ranked them the same way I did: the RE20 sounded best, the SM7B was 2nd place, and the Rode NT2-A was third place.
Have a listen to the samples below. I highly recommend using headphones to hear the subtleties. Also, none of the recordings were edited for p-pops.
First is the Rode NT2-A on "cardioid" setting WITH a pop filter (the sE Electronics meta l pop filter).
The next sample is of the excellent Shure SM7B wearing it's foam windscreen, but without an extra pop-filter:
And finally we have below the recording made with the RE20. There was no pop filter of any kind used on this recording:
My only quibbles are so minor as to be negligible. But I thought I should mention them. First, the RE20 comes with no manual. In the box is only a sheet with features and specs and the standard warranty paperwork. Now you may wonder why anyone would need a manual for a mic.
Well for starters, it would be nice to know about the bass roll off feature. The is a switch at the bottom of the mic that has a horizontal line on one side and a 45-degree angled line on the other. I can GUESS that this is a bass roll-off feature. But what frequency is used to start the roll off?
Eventually I found it mentioned in the extremely fine print under the "Architects' and Engineers' Specifications" section. It read: "when the filter switch is in the "on" position, low frequency response shall tilt down 4.5 dB from 400 to 100 Hz." That information should have been much easier to find.
My other quibble is that the mic came only with a plastic mic stand clip. That isn't all that uncommon, but compared to the SM7B's built-in bracket mount that buffers the mic from vibrations in the stand, it was a bit disappointing.
It actually became a problem when, out of habit, I connected the mic to my desk-mounted boom stand. I did a few recordings that seemed to have a bit too much bass in them. Then I realized that without a "shock mount" every vibration on my desk was traveling right up the mic stand and into the mic. My desk had essentially become part of the mic.
So I moved the mic to a standard mic stand that sat on the carpeted floor, and things became MUCH better. Since the RE20 is so often depicted hanging from desk mounted boom stands in radio stations, it's important to know that you need the 309A suspension shock mount, which you must buy separately, if you plan to mount it this way.
You can view the really detailed specs on the Electro-Voice site. But here are the highlights.
I want one. Okay, that's tree words. Whatever:). In fact I am going to buy one for a Spring present. That's a thing, right?:-P. Seriously, as much voice-over and singing recording as I do, the superior sound combined with the rejection of ambient noise and p-pops make this mic almost a necessity! At least that's what I'm telling the lovely and talented Lisa Theriot:-). UPDATE: I did that. The RE20 is my daily mic now.

I won't tell:).
