Westone Audio EAS30 Earphones


Westone Audio EAS30 Elite Ambient Series Custom Fit Earphones. Balanced-armature drivers offer comfort and detail.

Designed by musicians, for musicians, the custom-fit EAS 30 uses three balanced-armature drivers to deliver a crystal-clear sound, while still allowing listeners to take in a set amount of outside ambient noise from their surrounding environment.


Hearing is everything to a musician. Until now, musicians have had to choose between enjoying a dedicated in-ear monitor mix, or an ambient experience. With Westone Audio’s exclusive ambient technology, you can enjoy full-range frequency response from the monitor mix, hear your surroundings and engage with your fellow performers and audience like never before. The Westone Audio EAS30 In-Ear Monitor features three proprietary balanced-armature drivers with a three-way passive crossover, developed specifically to increase sonic detail and clarity. The soundstage features powerful lows, articulate mids and crystal-clear highs that are sure to meet the needs of any musician or music lover. Combine the performance of three balanced-armature drivers with our ambient technology, and the result is an in-ear monitor that has the performance, power and output for any stage, from a small venue to the world’s largest arenas. Let the world in, and set the stage for the best performance of your life.

Experience the Westone EAS-30 In-Ear Monitors

  • Westone Audio is the only company with a passive-ambient technology in their in-ear monitors which allows outside sound to filter in the monitors
  • Traditional monitors offer 40dB of sound isolation which is good but can cut user off from stage and audience feedback/sound
  • Provides a more natural feel by using the filter as a natural diaphragm which allows user to hear the artist the audience and bandmates in a more natural setting- Without this the musician is using a stage with microphones that can create artificial sound
  • Four different filters available (10dB, 15dB, 20dB, and 25dB) appropriate for each setting (small coffee house, stadium, etc.)
