Matrix Piece for IEM

Hello, I have a clean, functional, and well-maintained Matrix piece. - I've been using it for days with code 20; the reason for selling is that I've pulled it from all my work and will no longer be using the Sony. - I bought it for around 700; selling to the highest bidder—I hope there's no lowballing. - Reasonable negotiation is acceptable. - Any questions or inquiries—feel free to message me.
