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 EAS30 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.

  • Westone Audio Custom-Fit Technology
    Fully custom earpieces are cast, sculpted, and polished by hand from actual impressions of your ears, resulting in the best fit and acoustic seal possible.

  • Replaceable Filter Technology
    Westone Audio puts you in control of your ambient experience. With replaceable filters, you can pick your level of attenuation with 10dB. 16dB, or 24dB filters as well as the included 27dB solid plug.

  • Balanced Armature
    Westone Audio’s proprietary balanced-armature drivers provide enhanced sonic detail and frequency range that extends well beyond typical in-ear solutions.

  • Flex Canal
    This body temperature reactive material provides increased comfort and acoustic seal.

  • Cold Pour Acrylic
    Earpiece shells are cold-poured in acrylic for a thicker, more robust acoustic enclosure. This process increases durability and provides a more luxurious appearance.

  • Deep Open Bore
    The Deep Open Bore design provides a smoother transition between the monitor mix and the ambient sound and also increases comfort and acoustic seal.

  • Precise Acoustic Symmetry
    Left and right earpiece responses are matched to an extraordinarily tight +/-2 dB tolerance.

  • Replaceable MMCX Audio™ Cable
    Durable, supple, light-weight cable features low resistance and minimal cable noise.

Review and Rating


I've been using in ear monitors for the past 10 years. I started with cheap single drivers that worked but sounded horrible. Moving to these customs has made the music experience so much better. They fit like a glove and after about a minute I forget they are even there. The Ambient port gives me just enough so I can interact with the audience and not feel completely isolated. I really wish I picked them up sooner. I feel like they allow me to perform at a much higher level because I can hear everything I need to and nothing that I don't want to. I couldn't say enough about these.
