As the successor to the ES-la, the ES-2a improves on all aspects, including driver technology, housing, tuning, and much more. ES Lab is proud to introduce the ES-2a to both existing ES-1a users and those striving for the best electrostatic headphones on the market.\n\nLarge 90mm electrostatic driver with ultra-thin diaphragm\n\nThe ES-2a features a 90mm diameter electrostatic driver made of high-grade, ultra-thin Mylar film that is much thinner than a human hair. The diaphragm is driven by a pair of OFC electrodes which is only 0.3mm thick. This design provides powerful propulsion to the diaphragm, delivering an exceptional soundstage and detail retrieval. Each driver is assembled in a clean room environment with hours of inspection work and the strictest contamination control.\n\nEmbossed dust screen for distortion control\n\nFor the first time in the industry, ES Lab adopts an embossing printing process for the ultra-thin film dustscreens. By applying ultra-light compressions to the film, a matrix of embossed patterns is printed onto the dust screen, which is less than a micrometer thick. This minimizes distortion while making the dust screen acoustically transparent.\n\nOmega-inspired CNC-machined housing and removable earpads\n\nThe ES-2a housing is crafted from CNC-machined aluminum alloy parts and a nylon arc, recreating the classic look of the Omega. The earpads are attached to the chassis using a screw fixation mechanism. Swapping them out is possible for personal preference or future maintenance.\n\nPremium PU leather earpads\n\nEach earpad is crafted through a complex assembly process using PU leather.\n\nPC-Triple-C Pro Bias cabling with upgrade options\n\nThe Pro Bias connection of the driver is linked via a","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-es-2a-90mm-electrostatic-headphones-1204451862.jpg?v=1762906844","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-es-2a-90mm-electrostatic-headphones-1204451863.jpg?v=1762906957","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-es-2a-90mm-electrostatic-headphones-1204451865.jpg?v=1762906959","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-es-2a-90mm-electrostatic-headphones-1204451864.jpg?v=1762906853","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-es-2a-90mm-electrostatic-headphones-1204451866.jpg?v=1762906856"],"price":2000,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.011Z"},"share_url":"https://firestarter.network/l/lst_VVz8Z5eZ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
