I needed a wireless audio transmitter/twin receiver system so my producer and I could check and monitor voice recordings when filming. It needed to be a fast setup and not menu driven, just press and go with auto connection. This is just the ticket.HOWEVER! NOTE: Out of the box one of the two receivers broke when I gently pushed the power button. As you can see from the photo the button is sunk in at an angle, I didn't put any force, it just dropped in, clearly a quality control issue. So that stopped me from being able to review the entire system, but I moved onto the one that did work and have based my review on a single receiver and transmitter.The charger bay has a built-in battery that is chargeable via USB-C, just like those bluetooth earphone kits, it charges the receivers and transmitter from it's own held charge automatically as soon a you place into the slot. A charge percentage indicator display externally shows the charge status.Audio can be switched between Mono and Stereo for both Recording and Monitoring, this is achieved by a short fast press on the power button to toggle your preferred choice. Both Transmitter and Receiver have 10 steps of volume level using two buttons on the side marked + / - The Receiver has a recorded voice telling you "You are Switched to Stereo!" or Mono. You need ear or headphones plugged in to hear that.I found the audio quality to be very high, no noise, no distortion, unless you walk out of range. I tested externally with nothing blocking line of sight at about 90ft before drops off and Internally with rooms and stairs blocking the signal to about 30ft, which was impressive for such a low cost setup. The signal works on a 2.4ghz wavelengthThe build quality is ok..... feels kind of cheap in the hand but looks good, like metal, even though is all plastic. And of course one of my receivers broke out of the box. That said, the other one was fine, so maybe just a one off. To sum up, the audio quality is good. And that is what matters when monitoring.

Lekato is a brand that I hadn't heard of, but that I am quickly becoming impressed with. I have a couple of Lekato tuners, a Lekato bluetooth speaker/amp, and now these monitors. Everything I have from them has been a great value for the price. These monitors work just as well as much more expensive ones. I've only used a single receiver, but it has worked perfectly.

Ottimo rapporto qualita’ prezzo. Funzionamento ottimale, nessuna perdita in frequenza o distorsione, logicamente tutto dipende dalla qualita’ degli auricolari utilizzati ( non sono presenti in confezione).

Uno dei duri ricevitori non funziona, il tasto di on-off non permette l’accensione. Il resto funziona, ma lo rendo perché mi servono 2 ricevitori

My first experience with in-ear monitors (and oh how I wish I'd had them years ago, my tinnitus would thank me!) - these are a nice small package, good range, the receiver is very small and can go just about anywhere. The storage box will supposedly recharge the units off its internal battery (twice, according to the manual, but I've not run them down far enough to test that fully - and see charge note below). And there's a nice battery display right on the front of the charging box.Comes with an assortment of cables, and I've tested with both the 1/8" stereo cable (which has a 1/4" adapter), and with the USB-C "OTG" cable (both my Android phone and Win11 laptop immediately recognized it as an audio device and worked fine). Both receivers were already pre-paired to the transmitter, and worked right out of the box.One thing I've noticed is that there's a distinct lack of bass *in the transmitter/receiver pair itself*, not the earphones being used with it. I've read quite a bit about IEMs losing bass if the earphone seal isn't good, but that's not the issue here - if I plug the earphones directly into source the bass rocks your socks off, but with the same earphones plugged into the IEM and fed from the same source, it's rather tinny. If you're a vocalist or guitar player that might not be terrible, but for a keyboard or bass player (yeah, I'm both), it comes up lacking a bit. I'll continue to experiment and see if I can fine tune the experience, I've only had them a few days.Also, there are some oddities with battery status and charging - I didn't notice at first because I had the case plugged into USB-C to charge; when I removed it, the charge lights on all three transmitter/receiver units came on and the case ran down rather quickly (just a few minutes) from 100% to 90%. I then took all the units out, charged them to full individually on USB-C, and charged the case back to 100% - but when I unplugged it and reinserted the units (which I'd just fully charged) they all lit back up and the case dropped to 93%. Could be it needs a calibration run-down/charge up cycle or two but a little disconcerting.And lastly - the interior of the case has RX and TX marks reversed - it indicates two transmitters, one receiver, but it's actually two receivers, one transmitter. :-)
