Compatibility guide
For 64 Audio universal IEMs, such as the U12t, U18t, U18s, U6t, U4s, Nio, Volür, Ocean, Solo, Duo and the tia Fourté and Trió, choose Flat 2-pin (0.78 mm): they have flat 0.78 mm 2-pin sockets. Our standard 2-pin (0.78 mm) also fits, so choose it on a cable that has no Flat 2-pin option. The Aspire 1, 2, 3 and 4 are the exception: they use IPX (T2) sockets, so choose IPX.

IPX. Aspire 1, 2, 3 and 4 have IPX (T2) sockets, unlike the other 64 Audio universals, which take Flat 2-pin (0.78 mm).
No. The apex module sits in the earpiece shell; it does not change the cable connector.
