LEKATO MS-1 Wireless in Ear Monitor System, 2.4GHz Stereo in-Ear Monitoring with Transmitter Receiver Clip On, One to Many, Auto-Pairing,Wireless IEM for Band Rehearsal,Studio, Church,Small Gigs

Not only do the transmitter and receiver work very well, the company provides excellent product/customer support. My transmitter died suddenly and wouldn't turn back on. Lekato promptly sent a replacement unit, which unfortunately must have been damaged in transit because it also was inoperable. The company sent another and the third time was the charm. 10/10 for the product and the support provided by the company. Pain free, quick, and they didn't stop communicating until my issue was resolved. The wireless transmitter and receiver are plug and pay to set up, provide crisp clear audio, and excellent range assuming there aren't to many barriers between the transmitter and receiver. I can walk around 20-30 ft from the transmitter with a few walls and appliances and such in the way before I start to experience signal loss. Small enough to clip to a belt, waistline, shirt, or slip in your pocket. Included audio jacks and cables allow for operation straight out of the box, no assembly or extra kit required unless you've got something "different" you're trying to do with these.

I'm the keyboardist and one of the singers in my band, and I've recently started using these for both practices and gigs—and I'm really impressed. At the first gig, I tried them with some cheap dollar store earbuds, and the sound was fuzzy. I upgraded to better earbuds, and now the sound is great.One day, my singer and I swapped units to compare. She has a pair of the expensive $250 in-ear monitors, and we each used our own earbuds. Honestly, we didn’t notice much of a difference in sound quality. (I'm sure there's some, but we could both hear ourselves clearly in the mix.)Our band is now seriously considering switching to these for all our gigs. It would save us from hauling heavy monitors and might even help reduce our power needs on stage. There's definitely a bit of an adjustment period, but I think this setup is going to be a game-changer for us.

After a week, they quit working. I returned and purchased a new set. They didn't work either. Double checked my equipment and all is working. I just returned for another new set. Last chance.I am impressed with this small monitor system. The receiver/transmitter sync quickly and provide stereo or mono sound (as your mixer will support). It does have a small hiss/hum, but that is not noticed once you begin playing. A quality earbud makes a significant difference...while apple ear buds work, there is a noticeable difference using an earbud designed for monitoring (e.g., KZ ZS10 Pro).

I (try) to play guitar with our church choir, but in order to hear what I'm doing, I need an earphone connected to my guitar. And then there's the cord from the guitar TO the Amp - but that's already been taken care of by a separate UHF music transmitter/receiver (the box labeled Strich - it has 4 channels to avoid conflicts).In the box are 8 pages of detailed instructions and 4 cables: TWO male to male 1/8" (3.5mm) stereo (4-wire) plugs; USB-A to dual C charging; and a 1/8" stereo female to 1/4" male stereo phono jack. There is also, of course, the transmitter / receiver pair. The units are unobtrusively small measuring 1-3/4 x 2-1/8 x 1/2" (thickness not including the belt clip). In my setup, the output from the wireless UHF music receiver (transmitter is plugged into the guitar) is split - one to the amp and the other to a guitar headphone amplifier. The Headphone amp then connects to this UHF transmitter, the received signal is then fed to my earphones. So - - how did that lashup work?I first charged up both the transmitter and receiver (the system comes with a split USB-C cable that will charge both at the same time). The specs claim 5 hours operation on a single charge (I did not test that - but even if only half true will last longer than any are likely to play in a single gig). Each has a charging LED that is red while charging, and blue when fully charged. I switched both on, selected MONO mode (Guitar) then 'long pressed' the pairing button on just the receiver. Connection was instantly successful as indicated by the pairing status LED. After a power off / power on cycle, pairing was automatic. Volume setting is adjustable on the receiver (as well as on my headphone amplifier).There was ZERO lag - what I played was instantly in my ear. Fidelity was very good, no his, buzz, static or otherwise.My ONLY concern is theoretical - this is a single channel device, so if there is another 2.4 GHz signal at the same frequency (or channel phase modulation), there is the possibility of overlap (as I did not experience any difficulties, and I have Several 2.4 GHz WiFi transmitters, I did not make any deductions for that). This wireless In-Ear Monitor system works well for me (and if I do experience difficulty in a specific location, I can still fall back to the less desirable hard-wired solution).Bottom Line: I am NOT a Pro as far as music is concerned, and none in the group I play with (mostly brass, piano AND a hard-wired amplified harp) is likely to look for a wireless solution. So - while this works for me, it may NOT work for a large stage band. But - if it works for you, for the price, it likely can't be beat.

This looks like a great setup, easy to use (when it works). They worked great for a month, then they just stopped working. Nothing worse than being right in the middle of a performance and not being able to hear because your ear monitor system has quit. The 1st time it did it, I thought it needed to be charged, so I charged it. After charging, I tried it again, I played for 30 minutes, and it quit again. That has happened 8 times now, and now they are just dead.. Of course, they didn't start having issues until you're out of your return window. So now I just wasted money on junk.
