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

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 recently entertained at two-holiday parties. I was able to use the Xvive U3 Wireless Microphone System to send my audio mix across banquet facilities without the need to run XLR cables around the facilities. My setup consisted of a Bose L1-8, a JBL 10-inch EON powered speaker, an iPad, a NUX B-6 Saxophone Wireless System, an Audio-Technica 3000 Handheld Wireless System, and an iPhone. Before my first event, I tried the system out in my backyard to verify the sound quality, and to ensure the levels and sound quality would be the same as using XLR cabling. I placed the transmitter and the receiver about 75 feet apart and tried everything as if it were the gig. The line/mic switch enabled me to get the appropriate level on the secondary speaker. I had to set the switch to mic for the signal to be equal to that of the main speaker. Everything sounded balanced with this adjustment. The combined system sounded great with the two speakers being approximately 75 feet apart. The first event was on the patio of a restaurant. A parking lot was just outside the area and I was concerned that there might be some interference. I set the system up and verified no interference from any other systems in the area. Everything sounded great! Backing tracks, my saxophone, talkback mic, and house music. It all sounded the same as cabled. There were lots of cell phones and other electronics in the area. No interference issues. The event lasted 5 hours and the battery held up the entire time. The second event, this event was in a banquet hall. Again, I set the system up using the Xvive U3 Wireless Microphone System to send a signal to a 15-inch EON-powered speaker. Again, the system worked flawlessly. The transmitter on the Bose was approximately 75 feet from the power speaker receiver. Again, there were many cell phones and other electronics in the area, and there were no issues. This event lasted approximately 6 hours Excellent product. Works as advertised. Have not tried using the unit with a microphone, but the sound quality as a transmitter to create a wireless speaker setup is excellent. I plan to purchase another set to have the ability to run to a pair of remote speakers without the need for cabling. I would recommend this product to others.

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.

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.

Easy setup and works really well when used within close range (about 10–15 feet). I’ve used this for three live performances and many rehearsals in smaller, intimate spaces without issues. However, during a recent indoor festival performance where my setup was about 30–40 feet from the receiver, I experienced consistent interference through both my Xvive in-ear monitors and the speaker output. My signal chain was a Sennheiser e935 → Scarlett 2i2 & MacBook Pro → venue PA system. The system still functioned, but the static from the weaker connection was distracting during the performance. For small venues, rehearsals, or close-range setups, this works great. For larger venues or longer distances, you may need to keep your setup closer or consider upgrading to a higher-range wireless system. Overall, solid value and very easy to use.

I am a singer, and I sing at 80-100 concerts a year. I love a great microphone and I found one but it was wired. I really was looking for an affordable option to have the same mic quality but wireless and I found it with XVive U3. I love this system. From the moment I received it I was impressed with the packaging and the quality. It even came to me charged and ready to go. I used it at 2 concerts on Christmas Day and I must say I was pretty impressed. All I had to do was plug it in and make sure they were both on the same channel and oh there are 6 channels to choose from. Changing the channel was super simple and done by just the press of a button. The sound quality was fantastic. I was very impressed as was my sound guy. There was no delays, no interference, no dead air or dead spots and there is less than 5ms of latency. . It's not only flexible its portable and so easy to just grab and go. When I left my first concert and travelled 3 hours to the next I forgot to turn it off, but when I got there it was still charged and worked great the entire time. This is definitely my new go to microphone system to make my dynamic mic wireless. I love it and can't wait to try out their new wireless in ear monitor system next.

I was really skeptical when I initially ordered these but now I have several sets of them. They have literally changed my gig setup and breakdown and overall quality so dramatically for the better words aren't even adequate. I use them for my main speaker outputs from my board. Now I don't have cables running all over the place for people to trip over and it gives me a lot of freedom as to where I can place my speakers; as long as there's an outlet nearby I'm good. It also completely and totally changes the amount of time it takes to set up and break down because I'm not coiling dirty cables or trying to route them around furniture or through drop ceilings or anything. If you're a performer and you use XLR cables these "wireless cables" are amazing! The only thing you'll notice is that there is a reduction in signal so you have to increase your gain slightly if you're using them in "line" mode. They also can be used to make microphones wireless (which is their original intent purpose) in which case you would use them in "mic" mode which increases the gain. I now use them for that too so that my singers can use their own microphones and make them Wireless. Additionally the charge time is pretty reasonable at about 2 hours or so for a complete charge and they run my gigs on my mains for 5 hours without a problem and I have even stretched them much longer. This is an awesome addition to your gig setup! I have recommended these to many friends and theyve been thrilled! (no one is paying me to say this this is just one of those times where something is so awesome I want every performer to know it!)

I bought this device and was looking forward to using it with my Cannon XA40. When it arrived yesterday, I plugged it into the handle of my XA40, and it worked as advertised. Nothing said there were any compatibility issues. The real issue came when I went to unplug it from the XA40 Handle. The design of the U3 is such that when it is plugged into the camera, the body of the receiver fits tight against the release switch, making it impossible to press down the XLR release clip to remove it. It is now permanently affixed to the camera. My only option is to ship the handle to the repair shop to see if they can remove it by disassembling the handle. This means I have to wait a week and hope they can disassemble the handle and remove the U3. If not, I will have to buy a replacement handle. (The best price I have found so far is $375.) I have reached out to xVive for a resolution. However, they have yet to return my emails to them (other than an automated message to say they received the email). I have attempted to call the Customer Support line provided, but I am directed to a Voice Mailbox with no SLA on when to expect a return call. I spent $200 on this product for it to get permanently wedged into a $375 camera handle. Plus, I am out of the cost of shipping to send it to the repair shop and wait at least a week in hopes that it can be fixed. I am disillusioned with all this and very upset about how I have been left in the cold by a total lack of customer support. **Update 9 February 2023** The video repair shop has confirmed that the U3 damaged the XLR input. The design of the U3 is such that they cannot access the screws needed to replace the now-damaged XLR input. The only way to remove the U3 from the handle is to either destroy the U3 or the camera handle. Xvive Support responded with the following: "There has a lock button on your Canon, press that lock then you can unplug u3 receiver from it. Our design is same as common XLR output." So clearly, they have no desire to remedy the situation or even take the time to read the actual complaint. Please do not make the same costly mistake that I did. I really wish they would show any amount of true customer support.
