Verified Customer zZounds has verified that this reviewer made a purchase from us.
I live in North east Ohio and I am a professional ventriloquist and vocalist. I perform throughout Northeast Ohio and Western Pennsylvania. In my act I use a Fender speaker system along with a Pyle head set microphone. I was in need of an upgrade in the sound department. I found about zZounds via the internet and I purchased a Shure microphone headset unit. This was the best choice I've made in a long time. zZounds shipped my headset very fast. When I hooked the Shure unit up to my speakers I was literally blown away by the awesome sound being emitted from the speakers by way of the Shure headset. Thank you zZounds i will definitely be making future purchases from your company.
