Second owner, right iem has a blemish. IEMs were tested on the ultimate headphone test website via the quality/bass shaker test; they performed perfectly/without issue. Will come with the m15(installed)/m20 modules, carrying case and earbuds. No original iem cable from 64Audio, but will come with a 3rd party 2 pin 4.4mm balanced termination iem cable and 2.5mm balanced adapter. Looking for a firm $1400 shipped/insured via Paypal.

Also looking to sell the 2pin/2.5mm balanced Eletech Prudence iem cable for $150 shipped. If purchased with the U12Ts, will knock off $50.
