After long research, I think the kz duonic silver version is best for me as the red lion edition has quality control issues, Bunny is best among them all even it will outperform duonic silver but we cannot use other cable for replacement as it's connecting points are very long, Phoenix will have oxidation issues as it is full metallic and other great option is twistura d minor but it is very flat...., what do you think bcz it's my first time in IEM world as I previously owned CMF neckband pro and realme neckband 5 Anc, going to buy around may end,,,,
My priority is build quality (IEM mainly) so that it can last around 3 to 4 years...
2nd priority, sound: must not have muddy bass and high treble as I watch 4 to 5 hours lectures daily...
Thank you in advance for those who read this till end, give me your opinion too...
