The ES70 is a combination of our largest low-frequency driver used in the ES50 along with the masterfully tuned high frequency and mid-range drivers in our flagship ES80. This combination features a new crossover, designed to deliver reference level audio, shimmering detailed highs and harmonic content, while delivering the low-frequency information required by todays most demanding music. Equally at home on the world’s largest stages, or in the most intimate listening situations, the ES70 delivers extraordinary sound that has to be heard!

  • 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.

  • Balanced Armature
    Westone Audio’s balanced armature driver is significantly more compact and efficient than a traditional dynamic driver. Westone Audio monitors provide enhanced sonic detail and frequency range that extends well beyond typical in-ear solutions.

  • Flex Canal
    A body temperature-reactive, semisoft earpiece canal additive that stays firm at room temperature for ease of insertion and then softens at body temperature, allowing increased comfort and acoustic seal for incredible noise isolation.

  • Cold Pour Acrylic
    Earpiece housings are cold-poured in acrylic for a thicker, more resilient acoustic enclosure. Expect increased durability, a more controlled response, and a lustrous appearance from this Westone Audio technology.

  • Dual Bore
    With Westone Audio’s Dual Bore technology, high and low frequency sound components are channeled through separate passages in the sound port and sum within your ear canal instead of the earpiece. The result is audibly more natural and provides a more convincing transition between frequency ranges.

  • EPIC Replaceable Cable
    Westone Audio’s robust EPIC cable is constructed of bifurcated, high-flex, ultra-low resistance tinsel wire, reinforced with a special aramid fiber, and braided for ultimate durability, acoustic transparency, and isolation from mechanical cable noise. The MMCX Audio™ connector makes this solution conveniently user replaceable.

  • Handcrafted in the USA
    Meticulously built by a staff of dedicated artisans and lab techs, Westone Audio’s USA products exhibit a level of craftsmanship that truly embodies America’s rich history of handmade artistry.
