XviveU3 Wireless Microphone System 2.4GHz Wireless XLR Transmitter and Receiver for Dynamic Microphone, Audio Mixer, PA System (U3 Dynamic)

It only takes one frustrating experience during a live performance to turn a singer off of wireless for life! I've had more than one over the years, some due to limited range/interference, but mostly batteries dying mid performance. I said I'd never go wireless again.In addition to leading Sunday Worship, I am also fronting a classic rock cover band for fun on the weekends. Our sets are high energy, and we play in a wide variety of settings. Some venues provide plenty of room to move, and I found myself wanting more freedom to cover the stage, engage with my bandmates, and generally bounce around and have a good time! I wasn't thrilled about going wireless, but I also don't need to trip over a mic cable. Also, I LOVE my mic! A wireless mic of comparable quality was going to easily run me $400-500. Last but not least, I use a little pedal to provide some reverb and compression. I was unsure if the wireless setup would play well with my pedal.Then I saw the X-Vive U3! It was getting rave reviews, was priced well, and would let me keep my beloved wired mic. With Amazon's return policies and an upcoming gig, I figured I'd give it a try. Worst case I could return it if it failed to meet expectations.I was/am impressed! Super easy to use and set up out of the box. It's small and sleek, but solidly built. Had about a 40% charge out of the box, and the included double micro-USB cable brought it to 100% quickly.I tested it at home with my pedal and a keyboard amp. Mic --> Transmitter --> Receiver --> Pedal --> XLR cable --> amp. Worked great!At the gig I knew range would not be an issue, since it only need to reach my pedal, which I keep by the monitors at my feet. Sound was outstanding! I observed no latency or signal degradation at all.Most impressive was the battery life. We typically do a 3 hour gig separated into 3 sets with 5-10 minutes between. My intent was to charge the unit between sets, but at the end of the 1st set the LED indicator for 50% power had not yet come on. So I put off the recharge. End of 2nd set, same thing! Still above 50% charge! This little unit went the entire 3 hours and never got below 50%! Amazing!Got another gig coming up, so hopefully we'll see a repeat performance from the U3.

Disclaimer: No one gave this to me to try for free. I paid for it with my hard earned money.I don’t do a lot of reviews but this particular product far exceeded my expectations. I purchased the U3 Dynamic wireless mic adapter a couple months ago. I’ve wanted to go wireless for a while, but didn’t want to cough up the $850 for the Sennheiser 935 wireless mic. Like most other musicians I have a case full of microphones, but I love my Sennheiser 935 and don’t really care for the rest.I was skeptical of the quality of a wireless adapter but I am super impressed with this product. There are not many companies these days that under promise and over deliver, but this is one of them.I sing for about 2-4 hours a day and the battery lasts a long time. It last so long in fact, that I decided to put it on a stopwatch. Every time I would sing I would start the clock and stop it when I finished. It took 4 hours and 23 minutes for the red light to come on at the receiver. It was a total of 8 hours and 6 minutes before it started blinking. There were zero issues with sound quality for that entire time. I can’t say they are all like that, but mine certainly is. I tend to move around the room or venue when I sing so distances varied from 6-25 feet. It didn’t come with a charger, but I’m using a genuine Apple iPad Pro charger that has the usb 2.0 connector for the block.As far as the distance it works, I’ve only been able to go about 70 feet and there were zero issues.Another great thing about these are that they can be attached to anything you don’t want to use a cable for. Also, now that I’m wireless, there are some venues where I can setup before anyone arrives and this enables me to walk the entire venue and get the levels setup from the audience perspective.Sometimes I have friends that sing with me, so I plan to get a second one soon. It’s just an outstanding product. The only thing I can’t comment on is longevity, but if the quality I’ve seen at this point is any indication, I think it will last for quite a while.

I bought this to use with a Crown CM-311A headset mic. It's very easy to use, just plug in, turn on, and it syncs right up. Sound and range both good. I was walking around 40 or 50 feet from the sound board with no drop outs. The problem I have is that it makes a high whining noise when plugged into the Crown mic. I have an Audio Technica mic that it doesn't make this noise with, but the Crown is a better sounding mic. I contacted the manufacturer and they said some condenser mics with preamp circuitry make some noise. They suggested using a short extension mic cord to separate the wireless from the mic. I am going to try this, but not real happy about it, as it's just more stuff to worry about when on stage. I would rate this 5 stars if not for this problem, but I am going to keep it since I like everything else about it and I can make it work.Update 5/23. I've used this system for about a year and a half and been very happy. Lately though, it has started to change channels all by itself when I'm not even touching it. If I squeeze the case, it will make it change but when I'm on stage I'm not touching it. Really makes it unusable on stage. The battery life in the transmitter seems to be getting shorter also. Changing my rating from four to 2 stars because of the problems and relatively short lifespan of the system.Update 8/16/23. I contacted Xvive and told them about my problem. They emailed back and said it's out of warranty but would give me a discount on another system. After a couple more exchanges and a video of the problem, they agreed to replace the system at no charge. That's awesome customer service and I'm very happy with the outcome. I really love this wireless, it's much better sound wise than a cheaper system I bought from another manufacturer for a dynamic mic.
