User manual SONY MDR-EX76LP

[. . . ] To provide accurate sound and a fit designed for outdoor usage and portability without compromise, they are packed with technology that Sony has accumulated to date as well as Sony's own cutting edge technology. This pamphlet explains these technological components. Rich bass and expansive treble: Large caliber 16 mm diameter dynamic-type driver unit In the closed-body-type in-ear headphones, a large caliber dynamic driver unit that is the largest in the industry at 16 mm diameter was used. [. . . ] It enables a wide dynamic range available only with a dynamic driver unit and playback of a broad range of sound, providing a clear and accurate sound with incredible balance from the bass to treble range.

Liquid Crystal Polymer has already been identified for some time as a material that can provide a balanced combination of these two characteristics in high order. However, previously it could not be used to create diaphragms for headphones due to the inability of compositions and manufacturing methods to obtain sufficient heat resistance and the inability to achieve the thinness required for usage in headphones, caused by a low degree of film elongation and the difficulty of formation. To solve this problem, a highly stretchable Liquid Crystal Polymer was successfully developed for use as a casting film using polymer varnish. This made it possible to enable both rigidity and a high level of internal loss over a wide bandwidth, while also providing the level of strength required to stand up to the process of creating a thin film. This let us shave over 30% off the thickness compared to housings that use common resin material. Actualizing a highly stable fit for individual ear shapes: Flexible ear hanger using TEKNOROTETM For the hanger component, TEKNOROTETM, a plastic material that folds freely and maintains its shape was used. Because this material can alter the hanger shape to fit each individual ear, a superior fit stability is achieved. Also, TEKNOROTETM provides a comfortable and safe fit because it is lighter and more difficult to snap. Selectable by ear size: hybrid silicone rubber earbuds Newly developed, hybrid silicone rubber earbuds combine silicone of two different hardness levels. This new design maintains the shape of the earbud tips where sound exits by making the core firm, preventing sound quality deterioration via squeezing of the earbud tips. The outer portion is soft, and this improves fitting to the outer ear canal. Overall, the earbuds have increased enclosure and provide a more comfortable fit even during long usage periods.
