KIMAFUNWireless in Ear Monitor System, Personal Wireless IEM System Earphone for Musicians, Singers (1TX+1RX)

Much better than expected for the price. Very easy to set up and use. Basically just plug and play. It has adaptors for mono & stereo, and 6 different channels to avoid interference. Small and light weight, very easy to wear. The rechargable batteries are an excellent feature, and as far as I can tell so far they have good battery life. The earbuds are nice too. I like the way they fit, and wrap around the top of the ear. They also sound clear and crisp. I've only tried them at practice and not as a live gig yet, but so far I'm pleased. I had initially intended to just use them for practice, but now I'm kind of anxious to use them at our next show and see how they do. Come with all the cords and tip adaptors you might need and a nice semi hardshell case for storage. Has good, clear instructions.

Got this for my nephew, he’s 19 years old and plays in a band with his friends he said that the first setup out of the box to test, required no settings to be adjusted to work, hooked it up, powered it up, getting sound from his iPad for test, audio sounds very good quality wise, it appears to be loud enough, good spectrum of frequency response low to high, I think the durability factor will be fine.As far as distance between transmitter and and receiver, he walked about 50-60 feet away into another room with several walls between the transmitter and receiver, it was like I was standing next to the transmitter, no drops, no static, no volume or quality loss of any kind - perfect, no issues!As far as latency, he will be checking that and will update me based upon his findings. Earbuds are good quality and feel comfortable.

These are so very close to being incredible units. The headphones alone are really nice to listen to music with, but when attached to the receiver, it is just awful.I had two main issues. First was a high pitched tone predominantly in the left ear. It was much quieter in the right ear, but maybe that's just some hearing loss. lol. It is good to know though that at my age and having tinnitus, I can still hear some pretty high pitched tones. And, it was a totally different pitch than the ones from my tinnitus.Second, was just a white noise hissing whenever there was no signal being sent to the transmitters. So, with my tinnitus, It's like having an ocean roaring in my brain between songs. Since I wanted to use these for Mass, there is a lot of time between songs. By the next song, I felt like I had been hit by a tsunami. Taking them in and out or unplugging between songs seems like an extra step that would certainly lead to a music disaster. I'm not that good and adding complexity to the system is just an accident waiting to happen.Now, some of you may speculate that my sound system is not properly set up. And, on that you are very likely correct. I have no clue what I am doing really, I just turn knobs until something sounds good. But, all of these issues exist when the units are not even plugged into my mixing board. They exist on every single channel. So, it is definitely something with the way these are made.So if China had wanted to come up with a clever way to drive the world's musicians insane, they certainly hit the mark with these.I even had a second set sent to me to see if the first one was defective, but sadly, they both do it. I even tried each receiver with the other transmitter and it still did it. Hey, I'm an engineer, I'm going to figure out all the ways to isolate the issue and find the root cause. Which in this case is something in the electronics. I did not shut down my other electronics or wifi when testing because our church has wifi and all kinds of electronics which cannot be shut down for anyone. To me that just seems to yet another design issue.Guess I really don't need these fun little toys. Maybe if I ever get paid for a gig, I'll use the money to buy a high end set. Which by then, they should have better tech and better prices. Or maybe not. LGB!

I bought two of these systems (for me and my wife). Both took a lot of jiggling to work straight out of the box. Then after a few shows they both started constantly cutting out, needing jiggling to spring back in to life for a short spell. They look cheap. They feel cheap. The cost is cheap, however, they are completely worthless.

The media could not be loaded. My daughter has a small band....they do contemporary christian music and have been wanting to get into wireless IEMs. They have tried another brand which was honestly cheaper than this model, but it would cut out constantly and suffer interference. So far, she and her band have not experienced any issues with this model at all. In my opinion this has a solid build and performance. Perfect combination of performance and cost. The sound that comes through is very clear and robust. This unit does everything it says it does with excellence. No interference in a crowded radio space, other wireless devices for mics, guitars, in-ears, and WiFi routers. Sound is VERY clear with a little roll off on the low end, but that's fine for in ear monitoring since you'll get that low end presence from stage and FOH volume, and it's nothing some EQ management can't fix easily. I am amazed by the quality of this unit, especially by the low cost of this unit. Extremely happy with our purchase
