Pros: Voice presentation (check), Background isolation (Check), Soundstage (Check)
Cons: Build, Canal fit problem, Like any other in-canal earphones, noise cannot flow out
First time writing a review:
Bought it because I love good vocal from the song (especially enjoy oldies), not a bass-lover, not so much. Initially wanted Shure SE215, but at the store, the TWF 11 sounds better in vocal richness (No idea how long they burn in the earphones).
Initial thoughts before 100 hours burn in : It sucks. Blurred vocal, instruments. Bass overwhelmed everything.
After 100 hours burn in: Splendid vocal heard, vocal centralized in the middle, leaving the instruments on both left and right sides of the ears. I love details, and TWF11 has given me much music details, like the musical instruments..err.. tinging?
Bad: Poor fit to my ear, keep on twisting the earbud inside. Long hour of use often results in discomfort.
That's all. Thanks.
