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.

Great product to make my PA mixer wireless, can now send music directly from my computer and iPhone to the mixer with excellent audio quality, i have used it for my church services and the it covers a broad range with no loss of signal.Totally recommend it!

This Bluetooth receiver works great will recommend to anyone

love it works great

I teach voice lessons and do performances requiring mobile setup. This has been very handy in many performance situations. It doesn't have the longest battery life And it seems like it's getting shorter battery life with time. I've owned two sets of these for around 3 years And they are still very reliable. I would estimate around 5-6 hours of battery life. I finally decided it was just better to own two sets.

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.
