Pros: Sound, comfort, durability
Cons: Almost none- materials used could be better
These are realy great IEMs, one of the best sq(balanced with plenty of bass).
greatest thing of these is comfort- same as pl50, so perfect. i can't notice that im wearing them.
Sq is like Xears TD4, Pl50 and e10, so near top tier.
i only wish that materials used would like pl50, not pl30 type.
