The Westone Audio ES70 Earphones: A Reference Level Audio Experience for Audiophiles and Musician

The Westone Audio ES70 Earphones are a high-end, custom-fit in-ear monitor (IEM) that are designed for audiophiles and musicians. They feature a 7-driver configuration, with a combination of Westone’s largest low-frequency driver used in the ES50 along with the masterfully tuned high frequency and mid-range drivers in their flagship ES80 IEM. This combination delivers a reference level audio experience, with shimmering detailed highs and harmonic content, while also delivering the low-frequency information required by today’s the most demanding music.

State-of-the-Art Features for Sound Perfection

  • 7-driver configuration: Delivers a reference level audio experience with shimmering detailed highs and harmonic content, while also delivering the low-frequency information required by today’s the most demanding music.
  • Balanced armature drivers: Significantly more compact and efficient than traditional dynamic drivers, which allows for a wider frequency range and better sound quality.
  • Flex Canal: Body temperature-reactive, semi-soft earpiece canal additive stays firm at room temperature for ease of insertion and then softens at body temperature, allowing for 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. This results in increased durability, a more controlled response, and a lustrous appearance.
  • Dual Bore: Technology channels high and low frequency sound components through separate passages in the sound port and sums 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: Robust cable is constructed of bifurcated, high-flex, ultra-low resistance tinsel wire, reinforced with a special aramid fiber, and braided for ultimate durability.


  • Frequency response: 20Hz – 20kHz
  • Sensitivity: 108dB SPL/mW
  • Impedance: 16 ohms
  • Weight: 6 grams per earpiece

    Fantastic Upgrade with the Westone ES70 In-Ear Monitors!

    The ES70s are a superb upgrade over the ES50s, with noticeably improved treble extension and detail. The soundstage is far more immersive and 3D compared to the already stellar ES50. Robust, deep bass response with great extension reaches subtly lower than prior Westone models.

    The smooth, non-fatiguing Westone sonic signature remains, with airy yet never harsh highs. The pleasing midrange is present but not overbearing. The low end provides impact without bloat. The ES70 excels with all genres from jazz to EDM without fatigue.

    Westone’s renowned quality and craftsmanship shines through in the ES70. The included case provides rugged protection, while the optional 2-pin or MMCX cables prevent noise. Excellent isolation allows safe, comfortable listening levels by blocking ambient noise.

    For musicians, engineers, or audiophiles seeking outstanding high-fidelity in-ear monitors, the ES70s are strongly recommended over the ES50s. The performance jump is noticeable and worth the price difference.
