As a beginner YouTuber, crafting my setup was a lot harder than anticipated. I had never even heard of microphones like the CAD U37, and honestly was distracted by the search for the right video camera to pay attention to mic quality at all. That's the problem when designing your home studio. You have to be a master at everything.

You need to know which cameras look best and which microphones sound best, to start, Then you have to know what editing software has enough how-to videos on YouTube to learn how to use it. And when you go to look at a product like a microphone, you don't even know if the specs you're looking at are good or not! We'll take you through everything there is to know about the CAD U37 to help you decide if it's the right mic for you.

Similar Microphones to the CAD U37

There are a few budget microphones that excel, with the CAD U37 being one of them. Each of these microphones has their own unique characteristics that set them way above. The MXL 990, MPM-1000, and Blue Snowball Ice are examples of such a microphone.

MXL Mics 990, XLR Condenser Microphone (MXL990)
  • Perfect addition to any home or project studio
  • FET preamp with beautifully balanced sound
  • Provides silky sweet high end and retains tight, solid low and midrange reproduction
  • Vintage body style with champagne finish
  • Includes custom shockmount, mic stand adapter & carrying case

The MXL 990 is a condenser microphone that, like the CAD U37, sounds great for a low cost. The microphone has a generally flat frequency response that sounds pure and true. There's not a lot of pizazz thrown into the mix, allowing the microphone to capture a genuine sound that works great with voiceovers. When it comes to sensitivity, the MXL 990 isn't anything special and runs par with similar microphones. The same goes for the microphone's construction, although the metal body does put the MXL 990's durability above the CAD U37.

  • Studio grade recording without the price tag: Desktop or stand mounted condenser microphone with superior audio performance for crystal clear audio capture
  • Keeping your recording on point: Directional cardioid mic capsule perfect for podcast recording, gaming, studio recording and streaming
  • Sound you can trust: Smooth, wide ranging frequency response (20 to 20,000 hz) captures the full audible spectrum
  • Hear every detail: High sensitivity and low signal to noise ratio records every subtle nuance of your source audio
  • Everything you need for perfect audio capture, anywhere: Includes windscreen, shock mount, desktop tripod stand and xlr cable; Compact and lightweight form factor for portable audio capture

The MPM-1000 cardioid condenser microphone is yet another microphone worth more than its price. The microphone has a very tight cardioid pattern that does a tremendous job at canceling out background noise.

On the other hand, if you move around a lot, you may tend to move out of range of the microphone's pattern. Because of this, the microphone is more suited for podcasts and singing compared to casual Skype calls. 

Blue Snowball iCE USB Mic for Recording and Streaming on PC and Mac, Cardioid Condenser Capsule, Adjustable Stand, Plug and Play - Black
  • Custom condenser capsule offers crystal clear audio for Skype, Messages and FaceTime
  • Record vocals, create podcasts, and add narration to your home movies
  • Add crystal clear audio to recordings for YouTube. Frequency Response: 40 -18 kHz
  • Easy plug and play directly to your Mac or PC-no drivers to install
  • Snowball iCE is a USB 2.0 device (USB 3.0 compatible as per USB 3.0 backward compatibility specification).Sample/word Rate: 44.1 kHz/16 bit

With a similar price to the MPM-1000 and CAD U37, the Snowball Ice cardioid condenser microphone manages to hold its own against the two. It does lack features such as the CAD U37's -10dB pad and bass-reduction. The Snowball Ice stays competitive though through its smooth and warm sound. You have to stay pretty close to the mic to get the most out of it.

Diving Deep into the CAD U37

On the surface, the CAD U37 looks like any other cheap microphone. When you start digging in, however, this cardioid condenser microphone has a lot to offer. Packed with features and loaded with high-end specs, the CAD U37 makes a great addition to any home studio.

What the CAD U37 brings to the table

Plug and Play

With a USB connector and no drivers needed for installation, the CAD U37 is a very simple and easy mic to use. Whether you have a PC or a Mac, you simply plug in your CAD U37, and you're good to go. Doing this makes the microphone very handy for traveling and everyday use.

The CAD U37's large-sized diaphragm helps the mic capture low frequencies. Because of this, the microphone is suited well for the human voice. This means the mic is perfectly fit for tasks including recording podcasts, music or making Skype calls.

Cardioid pattern

Recording only what's in front of it, the CAD U37's cardioid pattern reduces surrounding noises. Because the CAD U37 is such a sensitive mic, the cardioid pattern is an essential tool in keeping every little sound from sneaking into your recordings.


Although you want your mic to be able to capture low-frequency sounds, sometimes you can have too much of a good thing. Sounds such as wind, bumping your mic stand, and HVAC systems have a low frequency. Turning on the CAD U37's bass-reduction helps you cancel out distracting noises which often ruin recordings.

-10dB pad

Further broadening your options, the CAD U37 also has a -10dB pad you can choose to turn on and off. Using this feature will help minimize any distortion or clipping caused by singing loudly or yelling. We don't know why you're recording yourself yelling, but you'll be set with the CAD U37.

Side-address design

Extending the CAD U37's podcasting and voiceover abilities, the side-address design of the mic helps you set up your home studio easily and efficiently.

Looking at the specs

Starting off, the CAD U37 has a respectable 16bit/48k sample rate, which beats the popular Snowball Ice's 44.1k sample rate. The frequency response is an equally impressive 20Hz to 20kHz. Like many microphones of its price, the CAD U37 only has one polar pattern. That polar pattern is the cardioid pattern which is best suited for solo podcasts and voiceovers. Keeping with the studio trend, the microphone is a condenser mic. This gives it exceptional sensitivity at the cost of picking up more background noise. The microphone weighs two pounds and dimensions of 7 inches by 9 inches by 2.5 inches.

Is It Worth the Purchase?

If you're looking to capture top-of-the-line audio, then obviously you're going to have to spend a bit more.
