I have one Sennheiser ew300IEM G2 Wireless In-Ear Personal Monitor System Bodypack and Earbuds FS. I bought this unit for a band and no longer play with them. Used very little. Retail on these is ~$525. Selling with shipping included $400. Again, this is the bodypack and headphones only and NOT the transmitter unit. The photo is from Sennheiser. I'll send actuals of my unit on request.

Bump. I realize this is a fairly specific item. Price is flexible.
