I recently purchased this UHF wireless XLR microphone transmitter receiver and I have been extremely impressed with its performance. The 7-channel wireless audio receivers adapters provide a strong and stable connection, allowing me to move around freely without worrying about interference. The microphone adapter plug-on with 48V phantom power is a great feature as it ensures my microphone receives the necessary power for optimal performance. The build quality is also top-notch, with durable materials that feel like they will last for a long time. Overall, I highly recommend this product to anyone in need of a reliable wireless microphone solution.

Not just wired MIC, also guitars, loopers, synths and a lot more! Now I don't have to be limited by cables when it comes to hooking up this instruments to my mixing board, my computer and active speakers. This opens up a lot of possibilities when it comes to my set up. For beginners I just started using it during a family karaoke the first night I got it as shown in the pictures. It was a lot of fun and there's little to no noticeable latency at all. It's almost like having a cable attached to my Sennheiser microphone. Both the transmitter and the receiver needed to be charged and on the same channel for this pair to work. The good thing is, it comes with a USB cable charger with the splitter so you can charge both at the same time. I immediately charged both of them when I got it out of the box to top off the current charge level. They also come with a regular 6.5 TS adapter if you ever need to plug them in to such jacks. The whole set came in well package and the quality of the transmitter and the receiver are pretty solid, you can tell just by the feel and look of it, that it is a high-quality transceivers set. We were able to use it within 30 to 50 feet distance away from the main sound system and there were no drop off or signal issues at all. One good thing I found out about it also is if you change the channel on the transmitter it will automatically change the channel on the receiver if you ever need to adjust it. So you don't have to go back-and-forth to the receiver to change the channel and match what you have on your transmitter. Just genius!Being battery powered there are some limitations on this transceiver set, the manual says up to five hours when fully charged. Another thing that I noticed when comparing the wired connection versus this wireless connection is the amount of hiss that becomes very noticeable when you turn the volume up on the amplifier that the receiver is plugged into.Aside from those two things that can be improved mentioned above, I don't have anything else negative to say about this product. As a matter fact, I might get a few more transmitters as this one can receive multiple transmitters in one receiver or vice versa. One really fun thing that I tried is that I was playing with my synthesizer quite away from the sound system and it was like so awesome, with no cables connecting the two. It was So much fun to be able to do it that way.

The sound is good. It’s a strong signal, no distortion. No interference…at least testing it at home. Appears to be built well and it’s easy to get up and running. Pretty good value assuming it holds up over the next few months.

I’m a professional performer, so I have high expectations for sound reinforcement gear. These pretty much live up to those expectations. They are straightforward and super easy to use. A long press on the power button toggles them on or off, while a short press toggles through the seven UHF channels available.When you switch channels on the transmitter (the microphone) the receiver automatically switches to the new channel. The seven channels are color coded. It’s important that channel selection is simple, because when I use these I’ll be using guitar wireless systems as well, and sometimes you have to do a little juggling to give everything a clear signal.I charged them up using the provided USB-A to dual USB-C cables. There is no charging block included, which is fine since I already have plenty of those. For a test drive, I plugged the receiver into a good Bose pa and the transmitter into my stage-favorite Shure SM58 Beta. The signal is clear and strong, with no noticeable latency.I have two other wireless mic systems, both of which have volume controls on the transmitter, and this one does not. That seems like it might be considered a disadvantage, but to be honest I am able to adjust volume and EQ during sound check, so I have never used that feature on the other units.This unit comes with XLR to 1/4” adapters for both transmitter and receiver. That makes it possible to use it as a guitar wireless system as well. I did not test it with a guitar, because I already have good dedicated guitar wireless, but the signal I get from the mic is so good that I’m sure it would be fine.I never use a wireless system with my studio condenser mics, so I did not test the 48V phantom power. In fact, the only mention of phantom power I can find is in the headline of the ad, so I have no idea how I would activate it on a single-button unit like this.So I’m not likely to use this for the more high-stakes shows, where I either use wired mics or high-end wireless systems provided by the venues. For my smaller, more informal shows, this looks like it will be ideal. If it’s anything less than excellent after I’ve had it in the trenches for a few gigs I’ll update this review, but so far it’s 5 stars for me.

Upon opening these up, I thought they looked nicely made. I gave them a full charge using the splitter charging cable provided. The first encountered problem, was the transmitter XLR fit (mic side), it fits too tight. I tried inserting it into several handheld microphones with no luck. Even trying to use it with the included 1/4 inch adapter, it still would not go on fully. Determined to test this out, I persuaded the wireless transmitter onto one of my microphone's (leaving scratches on the transmitter side). The noise level while using these is terrible. I tried all 7 channels, and lowered my mixer's levels, trying to get usable audio, but it just wasn't possible.
