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’s exclusive ambient technology, you can hear from the audience, fellow performers and the stage, but still hear the incredible audio clarity, frequency response and power that only a Westone custom-fit in-ear monitor can provide. The EAS20 has the range and output for any stage condition, featuring a dual balanced-armature driver design that delivers a robust low end and crystal clear highs. Let the world in, and set the stage for the best performance of your life.
Westone 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 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’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.
