Review: Exceeded all expectations - I hope this helps others, but I got this purely for Twitch streaming. I've so far used it in several different environments, first for a conference room roughly 20x20 (possibly bigger) in which it had to pick up everyone's voice clearly even in the back rows, and 2nd at my own house on a table to hear people talking at a table roughly 3x6. Here's how it worked in both environments: In Conference Room: Ok so for a USB device this thing is RIDICULOUS. I tested this against the Jabra Speak410 speakers and the MXL blows it out of the water for several reasons. First it's smaller, it's simpler to use, it can be concealed much more, and the sound is MUCH better. This device was able to pick up everyone's voice in the room surprisingly well and honestly it probably did just as well as serious audio equipment that will cost you x3+ more than this single device. To top it off for my instance of using this I needed to use this through a skype session and I was still able to hear everyone clearly even with the downgraded sound quality. In a room at a table: I'm able to pick up everyone in the room clearly as if they are right next to the mic. In fact this mic probably works TOO well for this situation. Simply because it can pick up everything around it, probably even better than my own ears. Roommates sometimes will have on a TV roughly 15-20ft away and it will hear EVERYTHING going on on the TV clearly, it'll even pick up when the front door opens and closes and that's a solid 20-30ft away around several corners. So like most great audio equipment it will pick up the sound clearly, but you gotta make sure you put yourself in the right environment to use it so it doesn't pick up background noises. If you are running a podcast, I would only suggest using this if you need to pick up voices from a crowd, or if you have a large amount of people on a single podcast. But in general I would stick with the other mics such as the Yeti devices
Review: Does everything asked of it and more - This was purchased to use in an environment that is, frankly, supposed to be beyond the capabilities of this microphone. We have just started webcasting our homeowners association board meetings. There are 10 board members in a horseshoe configuration in the front of the room, speaking through a central sound system with speakers in the ceiling. The room is 1800SF of totally open area and the audience in attendance numbers from 40-60 people with an opportunity for them to speak through a completely different, portable sound system. The mic was placed approximately fifteen feet from the center of the horseshoe, pointing towards the board members. The webcam (Logitech BCC950, also from desertcart) is placed about ten feet behind the microphone and is piped into the portable speaker system via a 50 foot 3.5mm to 1/4" microphone cable. The operator (me) sits at the table with the webcam and runs the webcast software we are using (Anymeeting) on a Dell 3521 Laptop. Since I make a bit of noise typing, changing settings and remotely turning the camera, I wanted some separation from the mic, thus the reason for the different location. The microphone picks up the board perfectly - crystal clear to those attending via the webcast. It works seamlessly with Windows 8.1 and complements the video from the Logitech very nicely. When live participants speak through the portable system, it also captures them quite well. When remote participants are "called on", their voice also comes through the portable system and is also captured nicely although will give them a lot of echo since it's sending the same voice back out over the webcast. I could mute the mic during their question/comment but then other remote participants wouldn't hear it so the speaker just has to turn down their own speakers while talking and everything is fine. The only "downside" to the mic is that it is so sensitive that it picks up ambient noise so if someone in the audience makes a quiet, off the record comment, it is often picked up even though spoken softly. Adjusting the gain levels will likely cure most of this problem during future meetings. Or people will learn that they are live no matter how softly they talk if they are within a few feet of the mic. I can't isolate it anymore than that since the room is somewhat crowded. Since the mic is picking up the board and participant voices via the speaker system, I may be able to actually move the mic to the very back of the room since location should not matter if the overhead speakers are all working okay. I remember the days when a microphone of this quality would cost hundred of dollars and now this is under seventy. It seems to be of very high quality, comes with a nice little carrying case. I do recommend the 15 foot USB extension for placement purposes - it's here on desertcart for five dollars or so.

*by M***N on July 13, 2023*

Solid conference microphone. Used it for my discussion book club's in-person meetup where everyone except 1 person was there in my living room. Said person was participating online, hence the reason for this purchase. Worked like a charm. The online participant could hear everyone's discussion clearly in a 180 degree cone. Good sound quality. All went very smooth. Recommended.
