AKG Perception Wireless 45 Vocal Set Band-A - Microphone system - black

I operate a hobby karaoke/DJ setup for parties with friends and family. I am by no means a professional, but have been slowly upping the quality of my kit. I had been operating budget priced Shure SM48 corded microphones for their durability and low cost of replacement, but with only mediocre to decent sound quality. I have been eyeing wireless microphones for a while, but was turned off by their high price of entry for anything of what I considered decent quality. I wanted a digital unit for their noise rejection capability, but all of those units are still priced into the stratosphere. I settled on the AKG Perception units as I was hoping they would be the best compromise between price and quality. When AKG offered them on special for 25% off, I jumped at the chance and bought two Band-A units with hand-held microphones. I was hesitant to purchase two units in the same frequency band, for fear of cross-talk. So far, I have only tested them in my 20'x30' garage. I operate one unit on channel 1 and the other on channel 8. Both units work flawlessly. Zero cross-talk, zero static, and zero drop-outs. Voice quality is brighter and clearer than my muddy sounding Shure SM48 wired mics. I have not yet tried them in an outdoor setting to test their range, and likely won't until much later in the year. Critiques: All of my critiques are leveled at the hand-held microphones. The mic handles are plastic and transmit some unwanted handling noise. Though, I give AKG credit for supplying rubber mic-stand holders that do a decent job of squelching handling noise associated with mics going in and out of the stand. The gain control slider/switch (I still can't determine if it is an adjustable slider or just a two-position switch) is ultra-finicky. Sometimes I think I moved the switch, but I can't hear a change, and other times I notice the change. Last is the "on/mute/off" switch. It is rather difficult to move the switch from "on" to "mute" without blowing right on by and into the "off" position. It then takes a few embarrassing seconds for the mic to sync back up with the receiver when you turn it back on. Maybe, it would be better if the "mute" function was a separate on/off button. Overall, considering the price of the competition, the quality of the AKG Perception is quite impressive.

Did not realize I was purchasing a factory refurbished by previously used items. However it works great and is in good shape. And I really appreciate the low price. I would be more certain before purchasing again from your store because I don't normally buy used items. I do think you should be more clear in your description
