I have my old trusty triple fi 10s for sale, it has a two year old null audio lune mk4 cable that it will come with and a set of small, medium and large ear tips. I don’t have the box anymore and since I’m consistently using my ciems I’m looking to thin the iem herd a little. Cost includes shipping in US. The iems work great and the null audio cable is starting to blue and harden a little. Makes no difference audio wise but they claim they fixed that problem in the new mk5 series.
