The magnostatic driverErmm... Unique Melody, Moondrop, and many more Chi-fi lol. I am talking about tri-brid IEM unless you are talking about Magnetostatic driver used in KZ ZEX.
KZ needs to drop these trash white tips.After burn in the Zex Def holds its own, it is a good set. The DQ6 is very nice but I have them neck and neck along with the EDX pro... Kz is doing good things. All of these are helped alot by tip changes.
