      True high-end sound

      Trusted Reviews

      An assortment of eartips is provided in the package of the ER4-PT earphones. The triple-flange eartips reduce sound an average of 35dB, which is approximately 98% noise reduction. The foam eartips provide slightly more (42dB) sound reduction. Lowering outside sound allows you to hear the full dynamic range of the recording without having to play it at unsafe levels.

      Etymotic invented noise-isolating, in-ear earphones. Etymotic's original insert earphone design, developed for auditory research and medical diagnostics, used balanced armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.

      Decades of research and development.
