Review: 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.
Review: Get for $40 what others charge $200 for - First off, this product was given to me for review. Now, onto the actual review! So I had the chance to review this mic over the last week or 2. I have used this to record 5 of my YouTube channel videos, and did a few livestreams with them as well. So for me, the biggest thing that I require out of any piece of audio equipment is that it works on Linux. The reason for this is all my content is shot edited and recorded on Manjaro KDE, but I am also a Windows, and MacOS user. So it is imperative that my audio equipment play well in all 3. To which, I can say that the K031B does just that. Pros- +UPnP Audio device +Works in Linux,Windows, and MacOS +Sound quality for the price is fantastic from both headset and Lav Mic +Build of the USB receiver, headset mic and lapel mic, and transmitter is good +Headset (great for livestreaming) +Lav Mic +Transmission range is quite good again for the price +User Replaceable Batteries +Good Battery Life (I was getting about 7 hours on cheap dollar tree batteries) Cons: -USB receiver is a little large so if your computer has all your ports crammed tight together could be a problem -Finding the right position for headset microphone will take some experimenting for best audio -Does not come with batteries for receiver -Uses a Mini XLR connector which could be a problem for some people. Overall, I am more than satisfied with the Fifine K031B. If you are looking for an affordable wireless lav or headset setup for interviews, livestreaming, church, or conferences this is a great affordable starting point. Those 200 dollar plus microphones just made it a lot harder to justify their cost.

## Questions & Answers

**Q: I'd have to put my bodypack near my cpu. i'm concerned this will cause interference. have others had problems with interference?**
A: I tested this unit both sitting in front of my laptop as well as walking around in a classroom and heard no interference on the recording.  I was using Skype for Business to record both audio and a slide presentation.

**Q: does this work with zoom meetings?**
A: Yes, you just need to go to the audio setting of zoom meetings and select the USB Audio Device as the microphone. And select the proper speaker as the output device.

**Q: How do i use this with a bose soundlink 2?  volume is low when plugged into the jack.  am i missing something?**
A: To output the sound louder, it's better to connect the speaker with the computer instead of the USB receiver. Then you can adjust the input/output level on the computer sound setting and turn up the volume on the speaker knob.
We recommend to use a speaker that has a 1/4 inch jack.

**Q: I hear a tiny bit of latency when using to amplify voice, any suggestions to decrease latency?**
A: We suggest you to turn down the volume and shut down other unnecessary applications and had better use low CPU software. Also please plug the speaker into the 3.5mm jack of receiver.

### ⭐⭐⭐⭐ Great!
*by M***N on December 22, 2019*

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
