Great video conference microphone.
This mic picks up an office full of people while sitting next to my desktop. I use it to allow three or four people to participate in a video conference in my office without having to reserve a conference room

Great Portability, Decent Sound Quality With A Few Annoyances
This microphone is one of a kind in terms of portability. It is very compact and easy to travel with. It is extremely simple in design with no drivers or software needed for installation. It’s a simple plug and play and comes with an extremely long usb C cable.Despite the positives there are a few issues with a strictly plug and play device. It has no way to adjust the gain. There is no software or knob on the microphone. This means what you hear is what you get. Your video calling software may be able to adjust it slightly, but typically it’s not good enough. I found that i sound a lot quieter using this microphone compared to my Blue Yeti.There is a built in noise cancelling that you can’t turn off which will automatically lower all the surrounding sounds, including your voice. This coupled with no way to adjust the gain is bothersome.The sound quality is worse than the Blue Yeti, but they’re the same price (or cheaper on sale). I purchased my Yeti about 4 years ago on sale for less than 80 dollars. The Yeti sound quality is superb. This sound quality is okay compared to it. People I’ve video chatted with say my microphone sounds far away. I’ve tried moving it right in front of my mouth and they say it has the same issue. This doesn’t have that crisp ASMR quality.You can’t attach a pop filter on it due to the odd shape. It advises you to put something over it to prevent moisture from entering the mic and potentially damaging it. There’s also no way to attach this to a standard mic stand.I definitely wouldn’t use this for gaming or live streaming as the quality is only decent and there’s no way to adjust the microphone. This would be fine for your simple zoom conference calls. I’d only advise this if you are only concerned about portability. There are better options if you looking for a permanent microphone setup.

Now I know why Sam Ash has such a crummy rating.
I'm not writing a product review. I'm writing a review to tell anybody. Don't order from Sam Ash. They told me it was going to be delivered in four days. After I paid for it, it went up to 9 days. And I know exactly what they're doing. You order it from Sam Ash, then they go to the manufacturer, order it for them, and then wait for it to be delivered to them, and then they ship it to me. A complete con job. No proof, but I'm not stupid.

Fantastic Value.
I'm not a sound engineer, but I have installed three of these in a noisy environment primary to voice control two computer systems.I think they are an excellent value. For conference calls they're da bomb. Voice control? All I can say is the weak link in the chain is definitely *not* the microphones.

build quality is amazing, but audio quality (and volume) is poor
this is better than many mics of this style, but the audio quality — volume specifically — is still too low for general table-top use. the build quality is amazing overall, tho ... too bad it's not good at the one thing it's supposed to be good for: table-top mic use ... even at 2 feet, it's still too low to use.

Good quality USB mic but not great
We use this mic for a variety of purposes but mainly for creating training videos. It's a solid USB mic but it not top of the line. We have an audio-technica mic that's similar that is better sound quality. It's about twice the price, but for professional uses that's not that much.I've also used as a conference call mic and it worked great for that. Overall it's a solid mic with good sound quality. If you're looking for _great_ sound quality you probably need to spend a bit more money. However if you're just doing a podcast or basic video production, it should fine.

A good USB choice in microphones...
MXL is the microphone arm of Marshall, the famous amp, speaker and headphone manufacturer. MXL manufactures a wide variety of USB microphones, ranging in price from $75 to $500. MXL is not an especially fine manufacturer of microphones. Their mainstay is podcast quality mics in the $100 range.And that's precisely what this mic is: podcast, Zoom, MS Teams-quality in a microphone, fine for use by professionals, but not a professional microphone. MXL suggests that this be used for making medical transcriptions. That could be a good use. It is sturdily made of an all-metal frame and mesh. it's small and can easily fit in a briefcase or sit below a monitor.Basically, this is a three capsule, 180-degree microphone made to be powered and record by being attached to a computer via a USB-A to USB-C cable (included). It is also possible to use a USB-C to USB-C cable, but that must be ordered separately.Sound capture quality is good-to-excellent for non-professional purposes. The usage case for this particular microphone is tied to its diminutive size: good sound at a conveniently portable and discreet size.

Disappointing sound quality. Wondering if possibly defective
I normally love the sound and quality of Marshall products but the sound quality of this MXL AC-44 mic is quite disappointing. It is so disappointing that I suspect I may have possibly received a defective device. The biggest issue is that recorded sound is too quiet. This is regardless of volume, gain setting, interface, or operating system. I tested on several machines and results were consistent across the board. I also tested in the MS Teams device configuration utility and sound quality was abysmal. In Teams it sounded both quiet and muffled. I’ve tried every tweak possible, and I also used several different headphones as well as PC and external speakers. I wanted to rule out every possibility that other hardware or factors were the cause. Nothing I tried made this mic sound better. I searched around online for others with similar experiences but did not find anyone else reporting the issues I encountered. Had I purchased the mic, I would have exchanged it to verify I do not have a defective device, but I do not have that option since it is being reviewed through the Vine program. I wanted to share my experience just in case there are any others who encounter the same issues. Performance quality aside, the size is small and perfect for mobile use. The metal body has a solid weight and feel and seems durable enough to withstand frequent transport. It is a great sized mic for a desktop also because it’s small and can easily be slipped aside out of the way while remaining connected. Most desktops don’t have a built-in mic, so it’s handy when needed and small enough to stay out the way when not needed. There is a thin layer of foam underneath the mesh body to protect the internal condenser circuitry from moisture. A windscreen or pop filter is suggested if the mic will be exposed to greater moisture exposure risks like outdoor elements or users who regularly speak within close proximity of the mic.

Low input levels and no customer support.
The input levels on this MIC are very low compared to the input levels on the built-in MIC on my MacBook Pro. Even with the MIC less than 2 feet directly in front of me, I pretty much have to shout at it even with the gain turned all the way up. This was a waste of money. What makes it worse is that I have gotten zero response from MXL Support. I waited over a week for a reply. Unfortunately, I threw out the packaging before testing it, so returning it is a problem.
