Worry-free Wireless!

We wanted you to know that all of the wireless systems you see here – and all of the wireless systems available at Sweetwater – are 100% compliant with the Federal Communication Commission's new rules governing wireless systems. You can be confident that these systems will work within the FCC's currently permitted frequency/power ranges. Please be aware that systems operating in the 617-652 MHz or 663-698 MHz range are now operating outside the FCC's new guidelines. To find out more, visit the FCC's wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones or give them a call at (888) CALL-FCC.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:

2-year Total Confidence Coverage Warranty™!
Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!

Absolutely happy with this purchase. Performs as described and better! I've used this for church events, weddings and outdoor video shoots. No RF interference and battery lasts. Great product for anyone who wants to turn their dynamic mic into a wireless mic.

I just received it a couple weeks ago and have already used it for a show and a few practice sessions... I could see getting more of these to eliminate speaker wires! I use it on my V7 mic....Great product!

OMG! This product has changed my whole system. I purchased a Bose S1 from Sweetwater and loved that it was battery powered which worked perfectly for my small professional magician gigs in private homes and small venues. The problem I had was that I still needed to plug in my wireless handheld receiver and run a cable to the speaker. The Xvive Audio U3 has solved this problem. I switched from a $1200 wireless mic and receiver to this... miracle and attached it to a... Shure SM58. I must say that in over a dozen shows, this configuration has worked perfectly! No more power cords, connector cables or dropouts!

The set-up is amazingly fast and the unit works flawlessly even when I am 65' from the receiver. It also comes with a Y connector so that you can charge both the transmitter AND receiver simultaneously. The 6 channels give me the ability to avoid interference which I have had only once. Switching channels took only 30 seconds.

This unit is magical! I am going to buy a second one as a backup. Anyone need a Line 6 wireless system? I am selling mine!!!

These transmitters have saved me more times than I can count. Great battery life, clear sound, and no lags. I've DJed an entire 4 hour party on these & going completely wireless has changed and made my setups look better with less wires running. I own 6 pairs of these and use them all for different setups. Love the crystal clear sound when using my Microphone.

I am finally free of mic cords. I bought a pair of these and they work flawlessly!
I just easily set them to different settings so they don't interfere with each other and I am set to go!
Easily recharged with included double lead USB charging cord. There is a "heft" to them that says they are well made.
Highly recommend these units to anyone who wants to cut the cord.
