Fantastic, budget lavalier microphone
In the box: The packaging for the Fifine Lavalier Mic is really nice. It comes in a plain white, and very simple box that contains the microphone, the USB receiver and the USB stick that goes into the computer. It also comes with an instruction manual, to help set up the device. There is also nice padding around the items to insure that the contents don’t get damaged. There is also a 3.5mm to 3.5mm cable included in the box. Setup: The setup of the microphone is very easy. The USB receiver takes two AA batteries, which are thankfully included in the box. The 3-pin XLR cable that is attached to the mic plugs into the top of the USB receiver. Hold down the power button to turn it on. Then plug in the USB stick into the computer and it will automatically install the drivers needed. After that, just make the microphone your primary sound recording device and you are good to go. Very simple, easy, and well explained in the setup manual. Only took me about five minutes to do. Quality of Products: All the products feel slightly on the cheaper side, since they are mostly made out of plastic. But despite the cheap build quality, all of the products function well. The Microphone: The Microphone has a pretty short cable which connects to the USB receiver. It is nice that the mic is wireless so you don’t have to fidget with wires when using it. The mic also attaches to your shirt via a clip attached to the mic. I found that I get the best audio quality when I attached the mic to the bottom of my shirt collar. Sound Quality: If the microphone doesn't sound very good at first, make sure you have the microphone set as your default recording device and have it clipped to the top of your shirt. Once I had done this, the audio quality was amazing. It was crystal clear with very little background noise. Given that the mic is wireless, I was pretty surprised. Overall, this is a great mic for starting Youtubers and for giving talks.

Working GREAT at the two month mark.
I have used this wireless microphone for about 2 hours, five times each week. So at about totoal 80 hours of use, I am loving it. I am using the microphone to make videos for my class as I am now teaching online. The sound quality on my movies, using this microphone, on a MacBook Air, using QuickTime and iMovie, is excellent. I read books and often do a voice over. I have no sound delay at all when using this product, not live, not with voice over. I have accidentally dropped the remote box a couple of times, from about 3-4 feet to the ground, and it has not broken. The casing is sturdy and the clip has a fine hold on your pocket or waistline as long as you remember to clip it on! The Microphone is about the size of a large grape, it is unobtrusive in my videos. I have not used the wireless headset yet. With the wireless microphone, I can walk around in my room and have a level sounding voice when recording videos. Overall, for the cost I think this is an excellent product. I read the reviews before purchasing this and I researched many choices. All of my concerns after reading the reviews were unfounded. I will update this if something changes, but I feel that this is a super buy for the cost and it solved all of my sound issues while teaching online. At this point, I would purchase it again and I would recommend it to a friend.

Great!
I use this for my podcast, and absolutely LOVE IT! I've been testing out a few different ones, and these had the best quality for the price. Recently bought a second pair for my co-host (I made sure to buy the CORRECT model this time, lol), and she loves it too! The headset is nice and lightweight, and even though it doesn't perfectly form around the back of my head, I don't even notice it. I got used to the subtle squeezing on my cheekbones very quickly. Even moving around, it doesn't bounce around. Only complaint here is that while the mic boom itself is adjustable, it really REALLY does not pack well for storage, unless it's being hung on a hook. I would like to see Fifine fix this. Both mics have cords that are plenty long enough to have the transponder hooked to the back of you pants, and the wire running up your back and around your body, with plenty of slack left. Both also have a great sound quality to them, with the transponder able to reach some pretty great distances (even with minor, physical interferences). Unfortunately the plastic "C" clip that clips the alligator clip to the lapel mic broke (my own fault for taking it on and off constantly to switch sides on the clip cause I'm too indecisive), but the clip itself is very nice. It's a metal alligator clip with a pretty large mouth, and a good, strong spring to keep a grip! USB receiver is a bit too wide though. So if you have 2 USB ports really close to each other, you might not be able to use the other one. It was a simple "Plug and Play" to it, and once you power on the transponder, it connects quickly and automatically to the receiver. The support team is PHENOMENAL too! When I bought my first set, I idiotically looked over the part in the description that read "will not work with mac/pc" and so I bought the wrong model. They quickly reached out to me after my initial review of THAT one (complete with admission of buying the wrong model like an idiot), and assisted with me getting the correct receiver so I COULD use it on mac/pc, and at no additional cost! I didn't ask for it or anything. In fact I had already set up for an Amazon return to buy the correct model when they contacted me. Lucky for me I hadn't set it out yet, lol. They even tracked it for me, and made sure it arrived, and I recieved it. They walked me through step by step on how to pair the transponder for the incorrect model to the new receiver they sent me. Made sure everything was set up properly, and that I was happy and satisfied! Even messaged me back a few weeks later to check in on me and see if everything was still going great! The best part was, it felt personal. In a good way though. I talked to just ONE person the entire time. It wasn't I talked to Steve one day, Bob the next, and Erica the day after. It was all the same person helping me, which made things a lot easier to correct when I had issues, cause they already knew everything there was to know before hand. That's 5⭐ quality customer service right there

I am only using the microphone with the clip and attach to my tie. The sound quality is good for recording myself while teaching. The USB plug and play works great. I can move around the classroom and keep connected.

Had to buy this in a hurry so that I could use it for Yoga classes on line. It proved very good and easy to arrange on the computer. The transmitting pack is not heavy, and the talking quality is easily understood by those who listen. I would recommend it for those doing Yoga or Qi Gong as I do.
