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

Update: While the product literature says they are charged when the red light turns off... I have found this to not be the case. The lit. also says a full charge takes five hours. Believe that! Charge for five hours and they will work for four to five hours is what I have found. (Technical note: I use a 20 watt Apple charger. See image for how I charge four units with one charger using: Duttek Multi Micro USB Charging Cable 1.5FT, 4 in 1 Micro USB Splitter Charge Cable, USB 2.0.) I have been using these Xvive U3s for two years. Synopsis: They have never failed me. No drop outs. Great battery life, well built, great sound. Not cheap, but for the money, a great value—way cheaper than "the real thing" (like a Shure Diversity system.) I use 2 sets every Wednesday night for an outdoor open mic (in Florida). The transmitters are plugged into my stage mics (Telefunken M80s). The receivers are plugged into a snake on the stage that is at the performers' feet, so the transmission distance is but a few feet (accordingly, I have no idea the range of these units). But given this configuration, I have never had a drop out and the clarity of the sound is indistinguishable to me from a wired mic—and I'm a stickler for sound quality—hence the Telefunkens when a Shure 58 would do). I set up at five. Generally turn the mics on about six-thirty, and run until ten to ten fifteen. I have never had one of these units run out of juice in this time frame. A couple of times, performers have dropped a mic with one of these units attached or detached a unit which then fell to the floor. Still ticking. (They landed on a thin oriental rug I cover the cement floor with.) Bottom line on construction: Rugged and well built. Brain-dead simple to operate. Just click a button to toggle channels so that receiver and transmitter match. Note: These are the units designed to work with dynamic mics (i.e., won't work with a mic needing phantom power.) Easy to charge—takes a couple hours. No idea how many charge cycles on the batteries, but I am in the neighborhood of a hundred cycles right now. Only beef: Wish the off button had some sort of fail-safe click or locking feature. It is easy to inadvertently leave one of these units on or set it back to on when you think it's off. Then you show up to gig with a dead unit. Going wireless is essential to me in running open mics. With performers getting up and down all night and with the need sometimes to move mics around on stage to accommodate keyboard player/singers, etc., it's a nightmare with cables (and it's unsafe as h.e. double hockey sticks). I generally have one acoustic guitar and a bass running wirelessly as well with the Xvives. No problems with that set up either (the guitar/bass units do run in the 5.8 GHz spectrum.) Buy 'em. You'll like 'em.

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've used this on a lot of gigs since purchasing more than a year ago. Easy to charge (even in the car on the way to the performance), easy to use, and works very well. Fully charged, I've never had concerns or problems getting through a 4 or 5 hour gig. One drawback is that if you're using a mic on a standard fixed, plastic (SM58-type) mic clip, the transmitter does NOT allow the mic to go in and out of the clip easily. Too big to fit through the clip. I use a spring-loaded clip instead, which solves that problem. I often arrive at a big band gig where there's one solo mic for the back row trumpet section to share. During setup, I unplug the mic, plug the receiver into the cord, plug the transmitter into the mic, and all of a sudden we can pass it around the section as needed without the complications of cable management. Worth it for that use, alone! And no coordination required with the sound guy, no need to allocate an extra channel or configure for his system, no need to collect the receiver from the board after the gig, etc. It's just sitting on the floor where I leave it plugged into the cord. To the sound guy it just appears to be his normal XLR cable input. Very transparent. I also have an older mic that I use for a cappella gigs. Different response pattern than any modern standard mics, but with this I can still use that one and get the response I prefer with the convenience and freedom of wireless operation.

With this product, you can make almost any microphone a wireless and untethered device. At this time not sure of the charging time, or the length of the charge (battery life). I have used it for 4 hrs. straight and had power. I should have bought it long ago. *-One less star for the cost. Pros: Sound quality almost excellent. Wireless mobility as a musician or speaker. Easy use. Compact to pack and travel. Works right out of the bag. A plug and play feature. Glad I made the purchase. Cons: Small and delicate. Don't drop microphone. On and off buttons are small and difficult to reach when placed on mixer, or amp. A how to video on the different ends of the mics should be created. Not for me but for beginners who wonder where to plug in the the different pieces of the equipment. I found it easy because of my experience with electronics, but most online videos skip this important feature. See you behind the microphone. AF~

A DJ friend recommended this product. I bought it to turn a second mic into a wireless mic for speeches at a wedding I deejayed. It worked great. Super good sound quality. My day job is as a teacher, and I brought it into my classroom for day-to-day use to turn a mic wireless so I could amplify my voice as I walked around the classroom. It worked so good. About 9 months in, it stopped working. It sounded like it had a blown speaker. Just terrible. I contacted their customer support via the manufacturer’s website, and they asked me to ship them the defective product, and they sent a new one back to me. They replaced the defective one, and I love having this tool back in my arsenal. Great product - I just hope it works for years. I will definitely activate the warranty so that I have a fallback if this second one gives me any problems. I have a few DJ buddies who use these dongles to send full audio (dancing music) to remote speakers at gigs, and they love it too.

Connects automatically. No noticeable lag. Using it plugged into a small Zoom AMS-24 2x4 USB-C Audio Interface velcroed to the back of my Ipad so I can have great audio when shooting video at gigs without having wires for people to trip over.

It was easy to setup. I hooked up Xvive U3T to my Sennheiser E935 microphone and the U3R to my mixer. It sounded great and distance was great, however if you speak very low or are whispering, it would cause what sounded like interference, cutting out, or losing WIFI signal. The green light on the receiver would flash when the cutting would occur. It was very annoying. You would actually have to speak into the mic or sing at normal levels for it to not cut out. The antenna must not be covered or behind and object or it would lose signal strength. I don't have anything in the house that is on my internet 2.4 ghz WIFI. The TV was on and I have another WIFI mic system running and that could be reason for the interference. Beside that, it is wireless game changer for your entire equipment setup, however I wouldn't trust it for large venue concert. I would definitely use it for weddings, small concerts, and parties. Update 12/26/19. I bought more from a website that offered package deal of 1 transmitter and two receivers for $250. I bought two package deals. I hooked up my mics, mixer, 3 active speakers (left, right, and sub). I was using it for karaoke. Music played nice through it but when I tried to sing. My mic would cut out or there was interference. I'm returning all of them and the two Sennheiser mics for this purpose. I will be losing $125 plus shipping cost for restocking fee. Update: I did a little research on Xvive U3 frequency range is uses and its between 2.440MHZ - 2.480MHZ. 2.4 ghz frequency range is 2.412MHZ - 2.484MHZ. On 14 channels only 1, 6, and 11 don't overlap base on 22MHZ wavelength separation. U3 starts on Channel 6 - 14. That means you can possibly use only use 2 of the 6 channels on U3 without interference with other U3s. You can use channels 1 on one U3 with another U3 on either 4, 5 or 6, or Channel 2 with 4 or 5, or channel 3 with 4 without interference with the other U3. However, if you a WIFI router, microwave, bluetooth, TV, or other 2.4 ghz items on the same frequency of U3 frequency ranges, it could interfere with the U3. 2.4ghz is very overcrowded compared to 5 ghz. That is my own research and conclusion, but I might be wrong. Update 2/6/20: I returned the set I purchased from amazon and kept the other two for mics. It worked flawless when just using two on channels that don’t cross interfere.

A dire il vero. Mi piace tutto di questo prodotto..

Easy to use and amazing sound quality. No feedback or noise interference. Battery life was decent. Very happy with my purchase.

Acheter pour remplacer le cable, et bin, le son a l'air meilleur qu'avec le cable. Très content de mob achat.

Es lo que esperaba recibir, buen producto y lo utilizo como remoto entre el micrófono y la mescladora.

Funciona genial mejor de lo que esperaba
