I am selling my mint condition 64Audio U12ts - 2023 editions. In late 2022/early 2023 64Audio changed the 2 pin connector in the IEMs to make it more durable so that is why you want 2023 editions vs older ones - told this by 64Audio. To the best of my knowledge I am the 2nd owner. I bought them last March. I have only used them at home while in climate controlled environment never to work out etc. I have replaced both screens today as one of them got loose when I was cleaning them. The screens are just held to the ring at end of nozzle with glue and easy to replace yourself. When I had them out and used a blue light LED and could not see any dirt/wax in the IEMs. They sound as good as when I got them and both left and right sound the same. Like an idiot I ripped the box cover sleeve so it will not come with that. I am selling because I recently got the Nios and they suit my music collection better. The tips are brand new - never been used by anyone since I swapped them with the ones that came with my new Nio - who uses stock tips anyway? Stock cable and outside of IEMs have been cleaned with alc pads. Today also emailed 64Audio to get proof these are legit and are 2023 editions - see pic. My price includes shipping - USPS Priority Mail with insurance medium box. Wiling to do UPS ground which maybe cheaper depending on where you are located and that could lower price. I will mail them out same day as I get funds and send you tracking number as self-serve machine at PO is available 24/7. I will pay Paypal fees. USA-48 please only. If you have any questions or need more pics PM me. Would be interested in trade for portable DAC like IBasso Dx320.
