Unfortunately my EarSonics SM3s just wonked out after less than two years of careful use. I've narrowed down my next IEM to either the Westone Eilite Series or Ultimate Ears Pro models. My main use for these will be for drum performance and mixing purposes, so I prefer them to be as neutral as possible. Although I mainly play & listen to progressive styles of rock. My other main concern is which of the two is better durability wise... Any advice would be much obliged.
