A:AnswerHello Anonymous!!!!!!!!! This set of earphones should be more than adequate. I play Steel Guitar and have no problem hearing the full spectrum of this instrument.

A:AnswerI didn't find anything on the Sony website, but they basically don't piece meal the parts (they want you to replace the whole thing). You can maybe try after market parts. Type in your model # and search that way (Amazon and eBay have a good variety). Hope that helps.
