Westone Technology

After many decades of in-ear and acoustic innovation, Westone has developed a sizable portfolio of exclusive technologies and incorporates only the most premium materials and optimal processes into all its products. Westone's Colorado Springs laboratories are the birthplace of these technologies and where engineers, designers, and technicians continue to pioneer new invention into the world of music and hearing. Find out why Westone is The In-Ear Experts®.


Westone True-Fit Technology
Fifty years experience with in-ear applications has yielded a low-profile, lightweight, universal earpiece with optimum ergonomics and fit. The True-Fit sound port delivers maximum comfort and in-ear coupling for dynamic transfer of sound.

Westone Custom-Fit Technology
Fully custom earpieces are cast, sculpted, and polished by hand from actual impressions of your ears. Since every ear is unique, Westone Custom-Fit tech offers the best comfort, fit, and acoustic seal to take your audio experience to an entirely new level.

Balanced Armature
Operating on different functional principles than traditional dynamic, moving coil drivers, balanced armature drivers are significantly more compact and efficient, allowing for a more comfortable, electronically sensitive, and sonically accurate end result. Westone implements sophisticated 2-way and 3-way multi-BA driver configurations to further enhance detail and extend the frequency response range well beyond typical in-ear solutions.

Flex Canal
A body temperature-reactive, semisoft earpiece canal additive, flex canal's unique properties allow the canal portion of the earpiece to remain firm at room temperature for ease of insertion and then soften at body temperature, allowing increased comfort and acoustic seal for incredible noise isolation.

Cold Pour Acrylic
As an alternative to most curing techniques, earpiece housings are cold-poured in acrylic which results in a thicker, more resilient and solid acoustic enclosure. Expect increased durability, a more controlled response, and a lustrous appearance from this Westone technology.

Acoustic Symmetry
Left and right earpiece responses are matched to an extraordinarily tight +/- 2dB tolerance, delivering unparalleled balance and accuracy of sound-stage reproduction.

Dual Bore
Typically, multi-driver in-ear monitors have a single-bored sound port, meaning the output from each driver will acoustically sum inside the earpiece housing. With Westone's Dual Bore technology, the high and low frequency sound components are individually channeled through two passages in the sound port. This allows high and low frequency material to sum within the ear canal, emulating the more natural phenomenon of live acoustic summation. The result is a more convincing transition between frequency ranges and is audibly more natural.

EPIC Removable Cable
Constructed of bifurcated, high-flexibility, ultra-low resistance tinsel wire and reinforced with a special aramid fiber usually reserved for ballistic-rated body armor, Westone's unique EPIC (Earphone Precision Interface Cable) cabling is second to none in audio quality, comfort, and durability. The robust, braided design resists tangles, while the integrated slider keeps your earphones in place during activity. EPIC's over-the-ear cable design also offers superior in-ear comfort and isolation from mechanical cable noise. Available MMCX Audio™, CX-Audio, and legacy 2-pin connectors.

EPIC Replaceable Cable with Apple Control
Stealth matte finish with Apple control, volume and mic for calls or Siri. Get the same benefits as the standard EPIC cable plus an added audiophile-grade, low profile connector system for a removable, user-replaceable cabling solution. Available on select products, EPIC Removable cables combine the performance of our exclusive cabling technology with the convenience and peace of mind of a fully removable cable architecture.

Made in the USA
Just as the best musical instruments are those constructed by hand, so are the best earphones which reproduce your music. Meticulously built by a staff of dedicated artisans and lab techs, Westone's USA products exhibit a level of craftsmanship that truly embodies America's rich history of handmade artistry.

SLED™ Technology
Westone’s exclusive SLED™ technology combines passive ambient sound with the monitor mix and gives you control of your musical environment. Enjoy full-range frequency response from your in-ear monitor signal, hear and feel your surroundings, and engage with fellow performers and your audience like never before.
