Etymotic Research ER-4PTPrice: $299


S. Andrea said: The Etymotic Research ER-4PT earphones -- and, even more, the ER-4 S model -- provide reference-quality sound in a vanishingly small package. Their level of transparency of detail is beyond what I thought possible from this type of device. They really are like having studio monitors that you can take with you wherever you go. Very highly recommended.
