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

I'm the bassist and sound man in our band and I bought one set to see if it could replace the XLR cable from the PA soundboard to the powered PA speaker. Tested okay! Slightly lower in dbs than the cable but adjusting the volume up just a bit made it work great. You have a mic/line switch to get the most of your signal in. I liked it so much I got another set. It makes set up and break down faster. I run one side on channel 1 and the other on channel 2, and have had no issues. I've had them running to around 5 hours, and they kept up. We usually go 3-4 hours. Make sure to fully charge ahead of time. Highly recommend!

This setup is awesome. Charge it, plug it in, and you're microphone is wireless. No muss, no fuss. Good distance coverage and great sound quality.

So I tried it for the first time on Dec 02 for my 10" JBL power speakers. Very easy to install and use. The only issue I had (it wasn't major) I had to have the volume on the back of my JBL higher than I usually do. So I like my speaker levels half way and then I control volume from my mixing board. In this case I had to have the level on the speaker on the 3 o'clock level. That being said the sound still was fine. Maybe I could of tried a different channel on the device? I'll try that next time and if the level is better I'll update my review. But it's still worth buying if you need a speaker a few feet away from you. I had it about 20ft away. You can also leave it charging while in use.

I'm a career audio engineer. I picked this up to help measure timing in sound systems. Not having to run a huge mic cable all over the venue would be amazing. I've seen a couple of my peers using them. I'm told there is no companding in these units as digital transmitters, and thus is accurate for timing where most conventional analog RF are not. I've found no documentation on these that discusses it though. The standard tool for this is about $2k.The Smaart trace is pictured. The self-latency consistently measured 4.38 ms. The straight red line at -4 in the transfer function is a cable, pink noise output to input. The green line is through the XVIVE. For the money I was pleasantly surprised to find it nearly flat +-1.5 db through most of the spectrum. There's a gentle roll-off starting about 7k. A touch of hi shelf EQ will likely to be helpful for transmitting voice/music.Bottom line I won't be using it for super clinical tonal tuning decisions, but that's not what I'm after anyway, just timing measurements. Used it just once so far, to approx 110ft, no issues.Comes with a clever dual micro-usb cable for recharging. And it's super nice that it's such a common phone charge port. Really happy so far.

Battery lasted through 3 hour gig without any issues. Good sound quality and easy to use. Receiving unit fit well into mixer without crowding other inputs.

If all you need is to mic a mic wireless in a limited range, this works great. For all other purposes, not so much.PROS: super easy to use plug and play which is great for one purpose and one purpose only: making a mic wireless.If you're DJing a wedding or event in a small to mid-size room, with no interference going on, you won't have any issues. Most weddings, you'll be fine.CONS: If you're trying to DJ off the thing and run a line signal through the transmitter, you won't get the same performance.I would not recommend using the line signal feature, or using this for anything other than a mic.For both mic and line, it starts cutting out at anything more than 30 feet, even though it says its a 90 foot range.

So I host outdoor car shows. And I wanted to run some speakers further out. I simply put the output where I would daisy chain my speaker and the input on the powered speaker that was far away . No issues at all. Played for 8 hours before shutting down. Never ran out of juice!

10 people around and the mic have drops, it was Less then 5 FT away from me ,I did not have the chance to use it and now it is too late so return ,It is beautiful and a Good idea, and great builtBut Save Your money
