Question about TIE Flex Mic Stand

in principle, yes... if necessary, buy the appropriate thread adapters (3/8"-5/8") here at digitec;
the arm is "cheap" and of inferior quality; I would personally mount the Hyperx Quadcast on a RØDE PSA1;
I don't have a Quadcast myself, but I ordered the RØDE PSA1 for myself (unfortunately the delivery time is "infinitely long...") and will throw away the inferior TIE Studio Flex (resinous, gnarled and I had to repair the retaining bolt several times because it is too weak).
