The first mic I got had a terrible high-end screech, and as I dialed down to the correct volume, a high-pitched digital "hiss." I played with it and could get it to reduce, but not go away. This is on a Sony RX10 Mark 4. I sent the mic back, rather than wait for an exchange, due to a deadline. To Fifine's great credit, they followed up with me. Even though I had returned the unit, they asked if I would like another one to test. Their customer service was excellent (which is why I had updated my original review to 3 stars. Good customer service is rare, and they should be recognized for it). I enjoy testing and technology, so I said that I would be willing to test another unit and determine whether I just had something wrong in the original unit, or whether the mic wasn't compatible. Today, I tested it on my interview set, using all the same settings as the lapel mic I'm presently using. I'm pleased to say that performance was stellar. Good, clean signal; no hiss. The mic element has pretty good response. I haven't distance-tested it, but I suspect it will be fine, as both the transmitter and receiver have external antennas. Unlike a lot of mics, you can change frequency as well, if there is any interference. I do have one thing I wished it had: a hotshoe mount. The receiver is strictly a box. Now I know it will be easy to get some sort of hotshoe mount bought or made and glue it on -- I plan to do that (I'll probably 3-D print it)-- not a major deal. So to sum up: Fifine took a negative experience, and turned it into a VERY positive one. The mic now works perfectly; you also get a headset mount which will be useful in some situations. The price is unbeatable. To be crystal clear: they sent this unit for me to test and provide an update. I like it so much that I will keep it, and I'll put a hotshoe mount on the receiver to make it work in the field. Definitely recommended! UPDATE 7/10: I added a star for customer service. I've been discussing the problem with them. They've been VERY supportive, and very interested in a thorough compatibility test. I'm going to try it again, and I'll update this review once I do. UPDATE 7/8: After more troubleshooting, I believe the problem is that the electronics of either the transmitter or the camera are not shielded appropriately (although I suspect the $34.95 receiver a whole lot more than an $1800 camera). I've decided to send it back - no reflection on the seller, who I haven't given enough time to respond, but I need this ready next week. ORIGINAL: I just got the mic today to connect to my Sony RX10 Mark 4 for some interviews I wanted to do. I have a Sony hotshoe mic, which has beautiful sound, but it was picking up too much reverb/echo from the room. When I connected the receiver to the camera, I immediately got a loud, high-pitched screech. I dialed down the input volume a lot and moved cables. Eventually I was able to get the background noise down to a high-pitched digital-sounding hiss. It gets dramatically worse when I turn on the transmitter, even with no mic plugged in. I tried moving the cables, changing channels,playing with the volume, but I just can't get a clean signal. It just may not be compatible with my camera. I've emailed customer service a few minutes ago; I'll give them a day or so to see what they say. Since I'm planning to do my interviews next week, if they don't respond quickly, I'll probably pick up a different brand and return this one. If the problem gets solved, I'll update the review and the stars. Review: The FIFINE Wireless microphone is a great deal for the price. - I did a unboxing video of this item it is on YouTube. You can just type the name of the item (listed in the desertcart ad) on YouTube and the video should come up. Channel TOON215. The kit is a great deal for the price and everything that comes with it. It came fast and was well packaged. It comes with many accessories also. I did a test outdoors on a busy street and the mic sounded pretty good. Again guys considering that this microphone cost less then $50 the minor problems I did have aren't even that bad. I used the mic during the test video and walked back and it started to break up and lose audio. However when I stood still both microphones this kit comes with sounded really clear. The lavalier microphone sounded nice out of a 1-10 on sound quality I would say about a 7-8 rating. It may have sounded louder if I placed it higher on my chest so it could pick up more audio. The headset microphone sounded AMAZING for the price. Other then the breaking up because I was moving around... it gets a 8-9 rating out of 10. The reason why I keep mentioning price is because there are not many cheap kits out there that come with this many pieces for such a low price and actually work. The audio breaking isn't that much of a big deal as long as your not doing a lot of movement and if you have somebody using headphones to monitor the audio coming from the camera. If your using this as a static(standing/sitting) still microphone... I imagine both of these little mics can be very useful. Great for documentaries, youtube channels and more. I would recommend this to a friend. Thumbs up...

Because this receiver output is about the same level as a wired mic. It must be plugged into a 1/4'' speaker input designed for a mic connection. If your speaker has only 3.5mm line inputs which require a higher level signal than a mic provides, the mic will be not suitable to be used with it, even you add an adapter. The sound will be soft and hard to be heard. **Q: Can I plug the receiver into my iPhone, audio mixer, or Mac to record the audio?** A: Sorry, it works with only audio mixer that has 1/4" mic jack. If you need a mic to use with Mac, we have the K031 (Asin: B074C125TN) USB wireless lav mic. But neither of them will work with iPhone. **Q: can it be used for singing** A: It will be more suitable for speaking than singing. We would recommend the handheld mic K025(ASIN:B0795PNCBG) or K035(ASIN:B01MT6AAIC) for singing. All these mics need to work with speakers/amps that has 1/4'' mic input. ## Customer Reviews ### ⭐⭐⭐⭐⭐ From Disappointed to Delighted! *by A***Y on July 7, 2018* UPDATE 7/17/18 - I am happy to change my original 2-star review to 5 stars!

Again! *by J***" on January 21, 2019* A month's time ago, a company that I had never heard a whisper about founds its way into my memory after I was put in my place by another of its products, specifically the K052 Gooseneck Microphone, which would inevitably outperform any personal, preexisting notions regarding its worth, accessibility, audio quality and more. Having thought that perhaps this case sat as a fluke or a "one-time" buy sort of scenario, I thought it proper to test the validity of it all, thus here we sit with the K037B, a microphone with its own story to tell. As to cause no confusion, I must relay the information that this product WILL NOT function will any form of computer-based equipment, even if you have a mixamp as I do, that is unless you have a mixer compatible with with the 1/4" MIC IN cord that will come with this product. That being said, with the 1/4" to 1/8" Adapter Converter Cord, you will be able to utilize this microphone with various cameras and camcorders, which is suitable for many content creators out there I am certain. But alas, it is a shame to not have the compatibility option for phones, tablets, or computers as a microphone as useful, clean, and reliable as the K037B would be a MAJOR asset for many on the Twitch/YouTube platforms. That does however lead to the question, "Is it any good?", and put simply, yes, and it all begins with the presentation. FiFine Technologies knows the proper method of boxing up their products to allows the consumer to feel confident in the product being opened, and with a smooth, clean, and appropriately sized container, a costumers worries go out the window. Furthermore, this same, delicate care shown to the delivery of the product extends into the longevity of the new relationship between consumer, seller, manufacturer, and support group as FiFine Technologies checks the boxes for all. Said costumer will find an extensive manual brimming with everything needed to get the product up and running but more enticing is the inclusion of a full two pages of listings for common issues, how to go about identifying said issues, and how to ultimately fix your situation. Now, some might point to Fifine wanting to reduce the amount of work they themselves need to do and perhaps this is to hide the fact that their product shipped undone, but I ask how can this be if said product is up to par with just about anything out there? How can this be for yet another stellar showing by this company? The K037B Wireless, Lavalier Microphone System is easy to understand, simple to setup and will be ready to roll in minutes, and provides an ideal environment for anyone looking for professionalism on any stage, big or small. All in all, FiFine Technologies delivers once again and my only downside is the lack of compatibility, but that is why other microphones exist. Not one can do every job but FiFine certainly knows how to do theirs.
