Review: Shure BLX4 Wireless miscrophone and Reciever. - This is a durable High quality wireless Microphone system. I used at weddings and parties and has never drop out once. It has connected even in a room of 200 people (with Cell phones in use). The connection is on spot and easy as 1 2 3. Shure is a quality product and this system is great a the lowest price you'll find for Shure. I have used 2 other system that has dropped out with smaller crowds and Short Distances. But this one has even gone into the next room. You'll be happy with this.
Review: This Same SM58 Receiver or Something Very Similar, Cost Me $1200 7 Years Ago! - This is a steal for this price. It truly made me think it was a typo. I believe the model I had before was the UX Series. Which is essentially the same as this, except the mic had a small LCD screen on it that showed battery power remaining. Other than that, there isn’t much a difference here. Of course, you get the same old reliable SM58 mic, that you will never have to worry about breaking. The only reason I’m replacing my UX, if I can’t find a replacement mic for it, as the buttons broke on it and I can’t change the frequencies any more. Regardless, this is essentially the same Mic/ receiver combo. With the only thing missing,Being the LCD screen on the mic itself. This is a pro model for a base model price. This Mic will allow you to travel a football field or two before you ever have any issues with break up. The sound quality is everything that you would ever get from any SM 58 microphone. Which is what all of the professional musicians use around the world.Has both a XLR and quarter inch jack in the back to allow you to plug into most any situation you would need. Overall, you will not get a better microphone for the price. And the fact that it uses AA batteries is a huge bonus over the 9 V I used with the UX, which would last two shows and have to be replaced. Whereas, the AA batteries on the new microphone last for at least four shows. Which is pretty amazing and AA batteries are much cheaper. You can buy 200 pack for 20 some odd dollars here on desertcart. So stop listening to me and definitely go buy yourself one now. I’m buying a second for back up and may consider buying more in the near future.
