Among the low cost wireless systems, price parity has recently been achieved in some cases. But again, anyone looking to buy a wireless system should do a features and benefits comparison to make sure they won't be spending more for a lesser system. Cuts in technology are the major thing the purchaser should look out for. When shopping for a low-priced wireless system, you have to make sure it's not a low price due to lack of technology and short cuts in performance. A lot of inferior wireless systems are purchased simply out of lack of knowledge.
People buy wireless systems without investigating what's out there.
They think all systems are the same and they purchase whatever the store salesman hands them. Certainly, if everything in the world were purchased intelligently, based on the best features at the best price, then there would only be a few players in the marketplace. Since the late 80's, other entities have come into the picture and the majority of them are the big established microphone manufacturers that have introduced their own wireless product line. In addition to that, more and more smaller manufacturers from Taiwan and Asia have started to import wireless systems under many different brand names.
