Up for sale is a 2-pin to 4.4mm Null Audio Arete Series MKIV UPOCC copper cable and a 2-pin to 4.4mm Null Audio Lune Series MKVI Silver/rare metal fusion alloy conductor UPOCC cable. They are both in like new condition in original packaging. However, I'm not a fan of the ear guides on cables so I carefully removed the plastic guides from these 2 cables. It has no effect on the cable other than increased comfort imo. Anyway, I'm looking for $60 for the Arete MKIV and $90 for the Lune MKVI. Those prices include PP fees and shipping in the CONUS. Thanks for looking.
