Hi guys, I am looking for new earphones that have 'somewhat' the same quality as my AKG K701 for mainly classical pieces. Will be using with an iPhone 4. Microphone is a plus, but not necessary. Sound isolation is definitely a plus. A portable amp recommendation would also be nice. Budget is about 150 - more or less.
I've been recommended the Klipsch S4i. What's your take on it?
Thanks in advance.
