KIMAFUN UHF Wireless Microphone System - XLR Audio Transmitter & Receiver for Dynamic/Condenser Mics with 48V Phantom Power | Compatible with Mixers, PA Systems & Speakers (U208A) | Perfect for Live Performances, Church Services, Conference Rooms & Studio Recordings

Using on my favorite microphone. I thought I would forever be tied to a cable until I found this. Haven't used it much so I can't speak to longevity but so far I love it.The GOOD:If you use ONE of these it's very clear and the range is twice the distance compared to a 2.4GHz system.The output is much louder than any other wireless system I tried. Very hot output.What sold me is the 48V phantom powered feature for condenser mics. I can't find this feature on any other wireless system. Very rare feature.The price happens to be cheaper than other system I tried which was a surprise.The BAD:It says you can run up to 5 systems at once. NO WAY. I tried to run 2 systems and kept getting interference and poor sound quality no matter what channel I was on. I tried ALL THE CHANNELS. In order to solve this problem (sort of) I had to separate the receivers 5 to 6 feet apart with an XLR cable instead plugging them directly into my mixer. This approach eliminates a lot of interference but not completely and still a fail in my book compared to what KIMAFUN claims. Running TWO at the same time is a challenge but it can be done if you do it the way I suggest. I reached out to KIMAFUN several times for support with no response. Customer service is non-existent. Another fail.My Applications:I'm using two. One to add a second speaker and one to run my 48V Phantom powered mic.Conclusion:If you use ONE, you'll be very happy. If you use TWO, it will be very challenging to make it work. My recommendation is to buy just ONE of these if you have a 48V phantom powered mic. Then buy a completely different brand as a second wireless system if you want to add another speaker.I tried Xvive (best sound for 2.4GHz), Sennheiser (very thin sound), Alto (lowest volume) and KIMAFUN.Audio quality was good. I was within 20-40 ft. It did cut out when receiver and transmitter are pointed in opposite direction, did not try it with antenna, so that might help. Pairing was quick and easy, and battery life was great. It is larger than I expected, but it works well. I would probably buy another set. I wished they used USB-C connector instead of mini USB connector. The connect does not fit all the way in, and it is flimsy and prone to damage. Charging is quick approximate 90 minutes to 2 hours for a full charge.I walked into a situation 1800 miles from my home base. The hotel where I was working told me "Our sound system is lousy! All it can do is pick up a radio station!" I got there and found a brand new 100% Bose system that worked perfectly (no radio station or sounds) until i plugged in an XLR. An AM radio station came on very loud and clear - even using shielded cable. I walked outside the hotel and saw the (50Kw) station antenna less than 400 meters away. I reasoned the station signal was so strong that the XLR cable became a cheap antenna. I ordered this product and had it in my hands in 20 hours (thanks, Amazon!) . NO RADIO STATION! Battery life is (dynamic, connected to mixer out port) is 5+ hours, sound quality is good.These units SAVED MY BUTT!!! I will order a second unit soon.I am running Recording studio and I have been using this with condenser microphone and it is satisfied there is no noise and sound quality is pretty good I am very happy with this itemThe product is easy to use and setup. I wanted it to use with my home recording studio to eliminate some cords. Unfortunately there was a latency issue that caused the vocal input to lag as it was recording. Another issue that I was unable to resolve was a slight distortion and “buzz” as it recorded as well as through the speakers live. I have a similar product connected to my keyboard with none of these issues.Depending upon your expected use, the product may work for you.The range is very limited may be about 8 feet and if somebody walks in front of it connection is lost. I am going to test further using the antennas. But at the moment I am not satisfied.It works as great as some other expensive brands. I purchase it solely for the purpose of their phantom power feature. This is excellent. I highly recommend it.Good productI record voice overs as part of my job and I like the idea of being able to occasionally un-tether my voice-over mic from my mixer for moments when I want to record myself when out of reach of my PC. This wireless link offers just that capability, but it comes with a compromise.I like the size, the build quality and how easy it is to get started. The batteries are built-in and they charge by micro USB. It's a very easy process to power the devices on and connect them to the mixer and mic - very plug and play.What you need to know is that this transmits via UHF. This is an older technology and it's an analogue radio frequency, not a digital connection like Bluetooth. The positive aspect of UHF is that the latency is nearly zero. If you notice significant lag when using this, it's your audio system or your PC, not this product causing it. The lag-free experience is great for live work such as giving a talk on stage at an event or for karaoke.One negative side of UHF is the audio quality. It's not that my voice itself sounds especially bad in the recordings (though it doesn't sound as good as when wired), it's just that there is white noise on top of it. This hiss is difficult to get rid of and I cannot get rid of it completely. Another disadvantage with UHF is that it's more prone to interference from other devices, power surges, passing vehicles and so on.I noticed that when running mics with phantom power and turning the phantom power supply (built into this product) on, I get a cleaner recording than when using mics that don't use phantom power. I think it would eve be useable for podcasting in a portable scenario, as it's fairly clean. I suspect that a Fethead or CloudLifter would further improve the signal to noise ratio of my non-phantom powered mics.To smmarise, if you're doing podcasts or studio singing and you want a clean signal, this is not the product for you. But if you're doing live PA stuff at church, on stage, at events, or karaoke nights this should work well. The range is plenty when the little antennas are screwed in.As far as wireless microphone adapters/transceivers go, these are decent with definite room for improvement. These are physically well built with visible defects; however, they are larger than expected and certainly seem larger than necessary (possibly due to inefficient batteries). They are easy to attach and detach from the microphones and pairing is a snap.The audio quality is fairly decent without noticeable degradation of the overall audio quality and noise is kept at a minimum MOST of the time. The bottom line is that there isn't noticeable difference between this wireless system vs. being wired which is of course a good thing. However, the signal quality isn't consistent I'm not sure what the issue is; it'd appear that there are some sort of interferences where there shouldn't be. The antenna doesn't really help with this particular issue though. Latency for the most part is negligible; however, the occasional signal issues do appear to cause sporadic short delays that quickly recover.All in all, these are decent wireless adapters for XLR microphones and for the most part work adequately well in most circumstances; however, consistent signal stability is somewhat lacking. I also wish these have USB-C charging ports instead of Micro USB which is way outdated. These are somewhat reasonably priced at $180 for what they provide.I have done some extensive testing within a DJing environment and a home studio environment. I am very impressed with the ease of use, simplicity and quality of these. Right off the bat - I highly recommend any stage operator, dj, church or club audio tech purchase a set and keep them in your gig bag - you never know when these will come to your rescue.First off, a nice package! You get a nice, hard case to store the transmitter and receiver, two extended range antennas and whatever else you may need to keep on hand. The quality of the tx/rx are incredible - for the price point. Feels like very high end product with quality assembly, body, readout and tactile buttons. Though, I do find the tiny buttons for channel selection a bit tough to use in a dark environment - so get used to them before you end up needing them in a live set. Though, I do warn you, the extended range antenna connections may be a weak point - they may break off inside the tx/rx, so you might want to keep an eye on that with rough acts.The use is brilliant. Connecting to Shure SM7b and Audio Technica P48 mics has worked like a charm. plug in, turn on, connect to mixer or audio interface and you're in business. There is not special process to get them paired. I cannot detect (without digital equipment) any lag, I haven't had to setup any delays to for compensation. Sound quality has been perfect for male voices (haven't tried female) with no obvious detraction in sound quality, tonal quality or interference. Range WITHOUT the screw on antenna is pretty good for line of site stage setups. I find any excess elevation or physical obstructions such as walls/stage equipment/etc you will need to screw in the antenna. I also noticed that only adding the antenna to the receiver tends to improve the coverage and have not yet had a need to use the antenna on the transmitter - which is something I think I'll do some more testing on soon.All in all.. I'm extremely happy to have these in my gig bag.. When not in the gig bag they'll be in use in my home studio just to stop moving around wires for the main setup.
