Selling a used pair of the original MASON. This is a 12 driver earphone that came out for the Japanese market. These come with the round circular earphone holder, the regular cable, plus a balanced cable. Also includes an extra earphone case and some tips. Photos include everything you will get. The balanced cable, attached, has some oxidation toward the ends but that does not impact on sound. Mason comes with 12 drivers a side in 4 low, 4 mid, and 4 high configuration. UM tuned the Mason in collaboration with Mix Wave specifically for the Japanese market, though it sounds exceptional to my non-Japanese ears. Asking $850 Also accepting trades - looking for a CA Vega, or full size headphones, Hifiman Ananada or Edition X v.2. Shipping is free within the states, but at cost for international delivery.. Paypal fees are for buyer.
