My T2 Plus connectors are still fine, but I honestly do baby these IEMs and have never swapped cables. On balance, basic 2 pin is still where it's at (especially with reports of the plastic section of QDC connectors shattering and everything)
To be fair, they were decent on the stock cable but with KBEar copper cable it's like a wind wane. I'm not a fan of QDC connectors standard 2 pin is best but will prefer QDC connectors over mmcx tbh
