AirSync - Wireless XLR Transmitter and Receiver, UHF Wireless Microphone System for 150ft Range, Rechargeable Wireless Microphone Adapter for Dynamic & Condenser Microphones, Mixers, PA System, USB-C

I used these and they worked perfectly. Great value for the money for budget Conscience ministry etc. Very easy to install and to sync ( automatically) . Great mic for group who just started up.

Trouble-free, easy to set-up, great audio quality, battery life. I have used two competitors and these are superior, even though they cost less. I use them in line mode between an Allen & Heath mixer and a pair of Bose Pro16s. They are the first transmitters that I can use while they are plugged into a USB charger without hearing the charger at all. I love mixing from the back of the room with no cable runs! On the front side, the airy tonal quality of a Neumann KMS105 comes through beautifully in mic mode, while freeing up our singers to roam the stage or the entire venue. Plenty of battery life for our 4+ hour shows while providing 48VDC for the condenser mic. Do be careful to ensure the XLR cable connector is latched! Lead singers can get real physical when unleashed from the cord... I have not used these long enough to know if they improve on the sketchy reliability of their competitors, but the initial impression of quality is remarkable at this price point. Happy Dance!

Worked well from a far distance on speaker system. Happy with Airsync and will purchase one more set.

Using it for half a year now and it is one of the best for its price. It never drops out and has decent range (at least 150ft based on the church venue I use it for). Plug into any microphone and it sends amazing sound quality with minimal noise. It works best with a super cordiod mic in my opinion but you can also use it with other mics. I would've given it 5 stars but my main gripe is that the battery life is not 8 hours as advertised but consistently about 4½ hours of straight use before it is blinking low.

This Air Sync Combined with a Shure 58 Mic is really surprising .Crystal Clear , Clean Vocals at a Price substantially lower than a Xvive ... Won't be long until I have a Complete Set ...

2nd UPDATE: The company reached out to me and sent me a replacement set to try. I have to admit, it wasn't that bad. It primarily worked this time just fine. I will continue testing. UPDATE: Used outdoors in a clear environment far away from any urban city, group of 100 people event, and these FAILED miserably. I was embarrassed. Constant "fwhip fwhip" noises as people talked or moved slightly. I tried changing the freq several times. I did not have a freq scanner, but no channel worked well. Sometimes even the audio just cut out mid sentance for 2 seconds randomly. Even when someone was standing TWO FEET away from the receiver it acted this way. I cannot recommend this anyone. Latency is really really good. less than 1.5ms compared to 5.5ms for XVive. XVive is flat 20-20, so can be used as a measurement system alternative wireless. This one cannot. The phase and roll off at low end are way too much. This would be perfectly fine for a vocal mic though. The transmitter/receiver device itself is too large to fit in a standard side-by-side in a regular mixer/input panel. So, you cannot use one consecutively in each channel, 1,2,3,etc. The power button is too exposed and can accidentally be turned off or on inadvertently. This looks like a branded version of something that is available or has been knocked off already. I have not tried the off-brand version, but I suspect it is identical and cheaper.

Long lasting batteries, instant connection, Amazing sound. Excellent build quality

The devices seem to work great, even with their moldy/mildewy smell. It seems that this device packaging must have seen water damage at some point in its storage or delivery phase. The box was riddled with a mold spores and there was a harsh mold/mildew smell. I would have liked to keep a box for storage with the foam inserts, but I immediately had to throw it away. My three star rating is not for the device, it is for receiving a rather disgusting package that was potentially harmful to my health upon opening.
