The e-Q7 are great with female vocals, but fit is a bit risky for very small ears. In that case I recommend the Final Audio heaven A (FI-BA-A1). These cost about the same and are easier to fit. I'd rate their sound quality even slightly higher, though build quality is not quite up to the e-Q7's. The CK100 aren't bad either, but I don't think they're worth their asking price.
Thanks. Which one do you think is better for Japanese female vocals the e-q7's or Final Audio heaven A (FI-BA-A1). I listen to a lot of Japanese female voclists old and new but mostly older ones like Zard. what are there sound signatures?
Thanks for your reply.
