XVive U45 Wireless In-ear monitoring system for musicians looking for an affordable yet professional solution for a wireless in-ear system. Item is nearly brand new as I've used it maybe 4-5 times in total and I'm selling because I upgraded to the U45D which is the same but stereo (this one is mono). Comes with all original accessories and case as well as original retail box. It is also still in warranty for another 5-6 months.
