Upon turning it on, the speaker is making a slight static sound and has not stopped. Perfect for a call center or working from home. I wouldn?t pay more than 15$ for it though. I tried a few different hook up and it?s the same. I am very please that I purchased the Wantek headset. I like this set, they fit great and have decent sound. These give better kicks when listened to rock. Weve tried multiple sets of batteries, and have checked to make sure that no wires were pinched, etc. It will do especially well with voice presentations in small to medium-sized rooms, such as in classrooms and business conference rooms. I actually think it makes the shoes look a little nicer too because it creates a decorative border across the top.
