This is a no-name rack mountable 2 channel In-Ear-Monitoring wireless system that comes with 3 receivers and 2 new sets of Sure 215 earbuds. I bought this system for use with my band, but the guys didn't even want to try them out - they insist on using monitor wedges. So this wireless IEM system has been in storage for the past year or so. Everything works like new (it should: it has never been used), the three receivers use AA batteries. The Shure 215s cost me over $100 each, so this is a real steal if you need a reliable I.E.M. system. Each channel has dual inputs for a true stereo experience from each I.E.M. The white tape is actually surgical paper tape and is easily removable.
