UHF Wireless XLR Transmitter & Receiver System, for Dynamic & Condenser Microphone and Guitar,25 Channels,98 ft Range, Rechargeable,Supports Adjusting Volume and Voltage

This is for the EALSEM ES-386 – For a first test I tested the wireless system at home in my office. Just like two other reviews said, it was only reliable when working up to 20 feet: From my office out its door and down a hallway; in a strait line of view. The transmitter was only reliable when stationary with no movement of the transmitter or receiver and with no one moving between the two. Because of those other two reviews saying it only worked up to 20 feet, I knew I had to test this out for myself. In this test I tried multiple orientations of the transmitter and receiver, not knowing the design of the internal antennas to test different planes of RF transmission, and I tested at the high, middle, and low points of its operational frequencies, with no appreciable difference in operation. I then took the wireless system to church, its intended operational environment, to test it. For the 40 foot distance it needed to operate in which is in a large open room, it work with no problems, even with movement of the microphone or people between the transmitter and receiver. So, in a home or close quarters it looks to have limited capabilities and should be totally tested before use. But then again, as with all wireless microphones, testing in any new environment, as best as can, before actual production use is the only safe way to proceed.With simple testing by ear, I could not detect any added hiss by this system. The volume control turned out to be a definite plus, and having an easily replaceable battery is a gigantic plus which was the main driver that drew me to buy this unit; I also required phantom power for an active dynamic microphone. I detest having good equipment that won't work only because of old batteries and having to break equipment open to get to a battery, only to discover it will take extra engineering to fit an available battery, if it is at all possible to replace. My guess is that this battery is a standard 14500 3.7 volt Li-ion battery in a AA package, having a bump on the positive end and being flat on the negative. When buying replacement/extra batteries read the Amazon reviews on them first: many of these batteries say they have a higher capacity (mAh) than they actually have. I will buy extra batteries in the next few months and update this review if I identified the type of battery inaccurately.

Pairing works. But no audio. Frustrating.

I wanted a wireless desktop microphone. This allowed me to have a wireless 3-pin connection. Battery lasts roughly 3-4 hours running on 48V. Comes with a split cable to charge both ends at the same time. Sound quality seems to remain the same and connection distance is great. Overall a very good product.

I found this just when I needed it. It is used to wirelessly transmit audio from the mixer to a smaller mixer for streaming audio. Order 2 for back up and plan on converting a wired mic to wireless when we are outside.

El producto que bien en un excelente empaque, la carcasa es plástica no es tan rígida, funcionalmente debes dejarlo posicionado en un sola posición , ya que si lo mueves mucho se interfiere la señal, lo que quiere decir que no serviría mucho para un micrófono de voz, probablemente para un micrófono estático cómo baterías seria útil.

I had no trouble connecting the receiver to the transmitter. I stood at one end of my moderately sized house and still didn't lose the signal with the receiver on the other end of the house. I foresee that it will be a valuable addition to my video recording equipment. I currently use wired Sure lavalier mics for recording informational videos. In situations where the talent must move around or it would otherwise be impractical to have them tethered to my audio mixer, the wireless transmitter will solve that problem. I do also have a Sure wireless lavaliere in my bag of tricks, but the receiver needs to be plugged into household current to work. These have the advantage of operating solely on battery power.I also tried them out as a wireless connection between a guitar and amplifier, and in this application it is a little less practical. The acoustic guitar that I was trying it out on has a jack on the side of the guitar, and the transmitter with the phono plug adaptor was a little bulky in that application. Similarly, plugging the receiver into the amp was less than ideal. With the phono plug adaptor attached, the 90-degree angle of the adaptor puts the receiver in a bit of an awkward position on the amp, and the digital display and buttons are all facing towards the amp with no practical way to see what is displayed.

I haven't tried it on a condensor mic yet but it worked great on a dynamic mic. I had some interference at first but changed the channel and it cleared up.

Really enjoyed this product for the first few gigs I had it for. However the connection is no longer sturdy and I get all sorts of disconnection when using it with my microphone. Very crackly and doesn’t produce the volumes it used to. Same channel on the Pa and everything. I have to push it to extreme DBs and then I switch to a cord and everything is blasting…. Very disappointed in the product and I don’t gig all that often so now it’s been too long to receive a refund for a faulty product… they say you get what you pay for and that I did… first red flag should’ve been the cheap plastic, but you live and learn
