The RWF20 by Rockville is the only product we know of on the market that will give you complete wireless freedom. This item is completely wireless! It does not need to be plugged into an outlet. It is 100% battery powered, including the receiver!

Our engineers did not stop there. We challenged ourselves to make the smallest possible UHF microphone system that is powered by batteries while still surpassing the range, sound quality, and features of the full-size systems by famous brand names. For this reason, we decided to make a UHF system with 100 selectable channels to ensure no interference in any location! Switching channels is quick and easy with our IR scan button that auto-syncs the mic to the receiver when you change channels. Since there are 100 selectable channels, you can use 10 of these systems at the same time!

The frequency range and sound quality of this system is spectacular. We compared it against a $300 system by a famous brand and we heard no difference at all. The microphone included in this system has a great feel to it and has a great sensitivity rating. The microphone is 70 % plastic and 30 % metal to give the mic the perfect weight and feel to it. The Rockville RWF20 will give you the ultimate wireless freedom and the ultimate sound quality for everyday use.

We are also offering a 90 day money back guarantee including return shipping. If the product is not as great as we describe it to be, then contact us and we will send you a pre-paid shipping label and give you all of your money back.
