Shure MVX2U Review - I want my money back 

Great video - simple, straight-forward and its good to hear the comparison audio.

Sorry could you elaborate on that "feedback loop" at 2:27? Isn't that supposed to be something we... DON'T hear? How is/was that happening?

I agree with this 100%. I also purchased an MVX2U last week, and it's very noisy with my SM7B. I was going to order a fethead to solve this, but since I am already using an XLR cable from my SM7B to the MVX2, thus creating more clutter on my desk (because I could not get the MVX2U to fit into my SM7B with my boom stand), I am returning mine too. I ordered a Vocaster 2 instead, and I will try that. I like the small physical footprint of the Vocaster 2, and they are all on sale now ($150 to $160 off from the regular retail price of $250). 😎

Had the same issue with noise floor…. Added a fet head and only run the SHURE adapter at 30 db that fixes it. Although expensive work around

One think I found this does great in is retaining the settings memory and then used on mobile devices like an iPad. That limiter is also soooo good and it's hard to distort this thing. It behaves similar to the limiter on my mixpre 3 but of course the preamp doesn't sound as clean. But portability and clean setup trumps a 10% cleaner preamp any day.

The shure sm7b preset on the rodecaster IS processed The dynamic speech setting IS processed That is why they sound different. The only way you can truly test the sound of each interface is to use NO presets and everything checked off Otherwise, nice video

The noise floor jump is a non-issue because no one should be intentionally bumping the mic in the first place.

Hmmm you are saying there is no processing done but when you went through the motiv app you switched the compressor to light, the "preset" is used. So all of that changes the sound. You should better switch all of that off including the Master compellor in the Rodecaster and the "presets' on the Rodecaster, meaning choosing "dynamic" instead of SM7B in the channel presets. Otherwise there are a lot of things that are actually being done to the sound, not groundbreaking things, but some....

What would be the best audio interface to connect sm7db? Scarlet?

Good video… can I connect a Ribbon-Mic to the MVX2u? Thank you.

I agree… RE20 is a better mic for folks with deeper tones in their voice… your voice sounds better on the RE20 than the Shure mics.

nice

So you return it to the seller because it lacks functionality? You did not realize that when you purchased it? Sheesh! I grow weary of reviews that diss an entry level product because it lacks features on more expensive, more fully featured products. Expecting the MVX2U to sound as good as your desktop interface is foolish right out of the chute - an apples to kumquats sort of thing. Nobody should expect a tiny device intended to be tiny and portable to outgun a larger, more expensive device designed for the desktop. I suppose you expect your phone microphone to sound as good as an external, aftermarket microphone. If you properly set gain and use the microphone properly, you will hear your voice and disregard the lorries rolling along the street outside. Playing just noise is a poor demo - research signal-to-noise ratio and you will be happy - but the fact one mic picked up more noise on one DAW - but the other less so on ANOTHER DAW means and proves nothing useful. You should run both microphones through the same DAW - recording two tracks at once. Using different recording applications can easily mean different gain levels - no matter what the meter or setting in the DAWs indicate, respectively. They are not likely to really be the same level, even if you set them to zero dB. Different levels of background noise may simply indicate differences in how each the software application works. The RE-20 sounds congested and boomy with unnaturally excessive bass - either Mic A and Mic B sounds much better with your voice in your particular venue - they sound much more natural, in fact you sound pretty dang good on your own - the RE-20 adds deleterious proximity effect which may sounds may sound cool, like a DJ, at first - but it is extremely tiring (fatiguing) and sounds artificial and processed when it is not. Go back to either Mic A or B on their respective interfaces. While I disagree with some of your points and procedure, it is overall a well done, to the point, well scripted video. Good luck and drive on soldier. JT
