Your review: We are a school district that is running a program that needs headphones with microphopnes on a daily basis. We have used many models over the last three years includng a behind the head set recommedned by the program vendor. we have found these to be not only less expensive in the intial purchase but also by virtue of not having to replace as many of them as we did with previous brands. We use at all grade levels K-12 and are very satisfied. I have just ordered another 75 for expansion of our program.
