Top of line in-ear wireless monitor by Audio Technica. I brought it new and have only used it once then I decided that I much prefer traditional monitor speaker. Still has its original box and comes with Audio-Technica EP3 ear buds, and rack mount ears. Brand new they are $799 at all major retailers. I am asking $575 Shipped US or Canada. I have an extra pair of Shure professional SE425 earphones that can be purchased as an option for $200 Shipped US or Canada.
