Got my Dark Saber a week ago. Left side 2 pin connector fit pretty tightly compared to the right. Tried to swap to using my Littlewhite and pulling the stock cable out pulled out the whole 2 pin socket and some of the shell. Reached out to Moondrop, they told me to contact the seller. Reached out to Apos, they told me to pay $425 for a replacement but could offer a 35% discount.
This is definitely the last plastic IEM I get that doesn’t fill most of the shell with resin, and probably the last Apos or Moondrop purchase I make.
Yeah this has been a known problem. Actually shameful that they didn’t give you a full refund, it’s purely the build quality fault of the Dark Sabre.
