1. Reversing the Starline Tips
The first tip for having a good playback on your oppoty is to change the tips. As we all know the stock tips are garbage and need to be flamed right away. Also the nozzle is so short that its hard to achieve deep insertion. I have tried many tips before like Spinfits CP100, CP145, Trn tips and KZ starline tips, however all of them is not that sticky nor comfortable, it also thins the midrange and reduce the sub bass (CP145) of the oppoty. Since, I don't have that much of a choice, I stick first with my CP145, however I also seek some suggestion in the audioreview group in Facebook, and fortunately I found some article made by the tuner of TRN BA5 that suggesting to reverse the kz starline tips. I tried to do his mod and the difference with my oppoty is night and day. The midrange thickens, the sub-bass increased, and the comfort is superb (bonus: its also sticky too). The tuner I mentioned also made a video on how to do the mod, you can just search in Youtube, "reverse kz starline tips" the first video is the one he made.
2. Changing the Cable to 8-Core OFC
Changing the cable is not that needed to say at least, but it's still a requirement if you want your oppoty to be durable. But in my experience, changing the cable to 8-core improves the midrange a little bit, it kinda lushes it in a way. However if you don't have that budget it's okay to use the stock cable, but you need to remove the plastic hook to achieve deep insertion. And don't worry about cable breakage if you remove the plastic hook, the plastic hook is not glued in the connector.
3. Removing the Mesh Grill (Optional)
This will add clarity and detail to your oppoty, however I don't recommend this mod since it will remove the unique characteristic of the oppoty which is the warm soundstage. To do this mod gently remove the grill placed on the top of the oppoty's nozzle, you can use a needle to remove the grill. And also remember that this mod is irreversible you can return the grill back if you're not contended with the mod. You can leave the nozzle without the grill (which I don't recommend) or you can buy a 4 mm mesh grill in shopee which cost 50 pesos.
