[30 Hours ] I bought my wife a Karaoke machine for Christmas which was two 1/4 microphone inputs on it. I was thinking how cool it would be to have wireless mics so people could hand them off as songs changed, instead of being limited by a cord, and having to swap seats. The WMS40 fit the bill PERFECTLY. I was a little concerned, with the low price, that the quality wouldn't be there, but the system is static free and sounds GREAT! I used balanced 1/4 cables (pulled from patchbay) to connect the microphone base unit to the Karaoke machine. The distance from the singers to the base unit is under 30 feet so I can't speak for the range of the unit.

[Non-Diversity] I was tired of getting tangled in cables and needed a reliable high quality solution for multiple instruments in my studio. I can’t beat it. Wireless pack is great and I never get any noise or signal issues.

[Dynamic] The clarity this system provided was outstanding. Are use the system in a medium size conference hall that accommodate it 250 guest. The wireless system was located in an electrical room. There was no interference and I really was amazed by its clarity.

[Cardioid] They sound great, good range, easy setup, as they are wireless, you do not have problems with the cables when you walk

[Battery] wonder fool

[Auto-Scan] I have dual wireless with a Korg rack mounted tuner and A/B switch. Great on stage and at practice. Allows easy switch between basses.

[Dynamic] We have 6 of these mics at our Church now. These are now the only mics we use. We love the clarity, the range and the single AA battery is awesome. You can spend more but it would be hard to get more.
We love our AKGs

[2.55 lb] I was asked to update the grade school sound system after they truncated the stage (and killed all the wiring) system. I bought all four frequencies and plugged they receivers into a wireless mixer. The school loves this system, no wires and the sound quality and battery life is really good. I liked it so much I bought one for myself.

[Handheld] I have bought two set of different Frequency Band (A & B) & (C & D). They work together, It is a product of good quality and low price and is recommended for smaller events, it is very useful and reliable

[30 Hours ] I have bought two set of different Frequency Band (A & B) & (C & D). They work together, the mics work perfectly for my set up. Nice that they use a AA battery instead of a 9 volt. Amazing distance too! I walked out into the street from my house and they still came in loud and clear.
