Talking about microphones is like writing about food.
No matter how elegant and eloquent your prose may be, the proof and the pleasure is always in the eating (or in our case, the listening).
Not so long ago, a group of Dutch voice-over pros got together for a shootout. They had been writing about mics for months. Now it was time to let the technology to do the talking. The goal was not so much to pick a winner, but to get a chance to contrast and compare.
For that purpose they threw about thirty mics into the mix, from shotguns to tube condensers. Among the mics they tried were the Brauner Phanthera, an Audio Technica AT4033, the Neumann M147, TLM103 and U87, the Sennheiser MKH-416, a Røde NTG3, a Telefunken U47 and an Electro-Voice RE27.
Then there was this very odd-looking mic from the United States, an E100S designed by Conneaut Audio Devices or CAD (see top photo). Very few people in the room had even heard of the brand, let alone seen such a microphone. But when the day was over, several voice actors ended up ordering one. By the end of this review you’ll know why.
Its reputation had preceded itself. Prior to the shootout, this rectangular shaped CAD had beaten out the venerable Neumann U87 – regarded by many to be the ultimate voice-over microphone – in a blind test. Not bad for a mic you can often buy for around $400!
ROBUST & RECTANGULAR
The CAD Equitek E100S as it’s officially called, is a side-address, large-diaphragm FET condenser with a nickel-plated 1 inch capsule, an 80 Hz hi-pass filter and a 10 dB pad. It has a fixed supercardioid polar pattern and the lowest self-noise rating of pretty much any mic: 3.7 dBA (measured with the capsule swapped for a fixed capacitor, known as the “capacitor substitution” method).
Coming in at 0.61kg (22 oz) it’s not exactly light. Made in the USA, this microphone is built like a tank and it feels solid but smooth thanks to a rubbery coating. It arrives in a nice cherry wood box, already resting in a specially designed ’stealth’ integral shock mount. You’ll find the XLR output at the back of the microphone.
Strong rubber bands tie the microphone to its snug-fitting shock mount. This mount works well, but it’s a pain in the neck to remove in order to place the mic in my Rycote InVision™ shock mount. Most people would only take the mic from its mount to replace the rubber bands, so it’s no big deal.
In my recent review of the Gefell M930 Ts, I came up with eight criteria for an ideal voice-over microphone:
- minimal voice coloration
- tight pick-up pattern (cardioid or supercardioid)
- excellent rear rejection
- controlled proximity effect (bass boost)
- low susceptibility to sibilance (shrill “S”-sounds) and popping
- low self-noise
- high-pass filter to cut out lower frequencies
- rugged design, ready for the road
To find out, I hooked it up to my new Grace Design m101 preamplifier and started talking. After all, that’s what I do for a living.
The following samples were recorded in 24-bit, 41,00 kHz WAV format and converted to MP3.

LIKE A LASER
Because of its tight pickup pattern, this is not a microphone for those who like to wobble and wiggle. If close miking is your thing, this CAD is king. Once you have found the sweet spot and you stay there, the mic will hear you loud and clear.
It zooms in on your voice like a laser beam, with the accuracy and clarity of a shotgun. Although sonically different, this makes the E100S a serious alternative to the popular Sennheiser MKH-416, which costs more than twice as much.
Let’s talk about your recording space for a moment. Soundproofing a studio or improvised booth can set you back thousands of dollars. If that’s out of your range, the next best thing is to find a mic that’s not so sensitive to ambient noise. That’s another reason why this CAD makes an excellent voice-over investment.
Off-axis sound spills are kept to a minimum, and yet this mic never sounds one-dimensional. Like a fine Bordeaux, it has a nice open and full body to it.
By engaging the high-pass filter, you can also minimize low-frequency rumble from boilers, pumps, planes, trains and trucks. In other words, under less than ideal recording situations, the E100S can save the day.
Sometimes, outside noise is not the problem. Every microphone produces electrical noise, known as equivalent or intrinsic noise. It can be utterly annoying. As a narrator, I don’t want my softer reads to drown in microphone hiss. Of course noise reduction software can come to the rescue, but with this CAD you’re not going to need it.
This is hands-down the quietest mic I have ever laid ears on.
Most supercardioids suffer from a more pronounced proximity effect, and with a wide open grille, this mic is no exception. You will also need a pop filter to take care of plosives and mouth moisture.
Like most reviewers, I do my very best to find fault with the products I’m evaluating. In that respect, this CAD gave me a hard time. There is one thing I struggle to understand, though.
In my opinion, the E100S has all the characteristics to become a voice-over’s secret weapon. Why then, is this microphone a virtual unknown in my line of work? Why do colleagues drool over Sennheisers and Neumanns, calling them “the industry standard,” while ignoring the silent quality of CAD craftsmanship from Ohio?
After reading every review ever written about this CAD and testing it for months, it finally dawned upon me. The E100S has one thing that’s both a strength and a weakness:
This microphone is an everyman’s friend.
It can handle sounds as loud as the engine of an airplane and as soft as a woman’s whisper. It loves strings just as much as percussion. Whether it’s used to record the subtleties of Baroque music or the unrelenting power of Punk Rock, this uncompromising CAD can capture it all.
In terms of marketing, the more universal the product, the harder it is to come up with a unique selling proposition. Not everyone looking for a voice-over mic will find the label “all-purpose microphone” very appealing.
Secondly, because this E100S is relatively affordable, it’s easy to equate low price with low quality. Perhaps my colleagues would take this mic more seriously if CAD would double the price.
Before that happens, I recommend you seriously consider this amazing American microphone.
After testing many makes and models, one of Holland’s most respected and experienced voice artists summarized it perfectly:
“The E100S is incredibly versatile. If I could only keep one mic in my locker, this one would be at the top of my list. I would gladly part with microphones costing more than eight thousand Euros in order to keep the CAD.”
This review is from 2012, and CAD has discontinued the E 100. In 2022 it was replaced by the E 100 SX, a microphone that looks almost identical to the E 100 S. However, under the hood things have changed and my first impression is that it sounds just a bit warmer. That’s not a bad thing in my book, because I thought the E 100 S sounded a bit “clinical.”
