GTD Audio 4-Channel UHF Wireless Microphone System with Adjustable Frequencies - 4 Lavalier/Lapel/Headset Mic Kits (400ft Range) - Ideal for Churches, Conferences, Classrooms & Live Performances

These are not senheiser's or shure's but at this price point they are an excellent solution. I purchased 4 units (16 microphones) and very happy with the result. My wife runs a small youth musical theater and for the last few years we have been renting wireless mic's from an audio rental outfit. The mic's we got were either senheisers and shures, so I know the quality of those expensive solutions. The issues we experienced with the rental microphones is that the company we rent from just had very poor quality control. The wireless units were always dirty. not looked after very well and the transmitter packs were always broken (antennas falling off or disconnected or some other battery problem). After the last rental where we received 16 mic's we only had 4 working mic's in the set and after dealing with receiver issues because half the receivers were missing antennae's we decided to invest in our own wireless mic system. Obviously at the price point we were able to afford we were not going to be able to get senheiser's or shure's. After a lot of online research of systems in our price point I settled on these. While there was not a lot of information online, the little I could find only had favorable things to say. I took a chance and extremely happy with the result. The sound is clear and the transmitters work extremely well with no cutting out once they are set on a clear channel. Finding clear channels was a challenge and my first attempt was just plug and play and I had a lot of cutting in and out. After I read the instructions and learned how to find clear channels I was able to get all 16 mic's working without interference.Overall I am extremely happy with this solution and would highly recommend it to any small aspiring theater/musical theater groups. While it did come with a set of headset microphones I opted to purchase the GTD over the ear microphones. Search for that product using ASIN B008FTJ4XW.
