"tecno, heavy metal or rap"...
- UE Metro.fi2
- Mylar X3i
- Shure SE110 (lighter in bass than all the above).
Anyway, I renew my advice to the Op to get the iM716. They are a steal under 100$. They are close to Etymotic ER4P, but warmer and with more bass. Very detailed, nice&clear music presentation. Best bang for the buck under 150$.
I didn't really like the d-JAYS, they made too many things wrong for my music preferences (light bass, suffocating/nasal vocals, overpowering electric guitars).
