{"type":"firestarter.listing","listing":{"id":"lst_HJG5xuWv","product_name":"ES Lab EX-1a Electrostatic Headphones","category":"Headphone","description":"Note: Transit on these headphones generally ranges 2-3 weeks from order placement.\nHigh-Performance Electrostatic Design\nThe EX-1a represents ES Lab's latest innovative design, after the flagship ES series. It's engineered to deliver performance that approaches that of their flagship model, while also having its own strengths and characters. The EX- 1a caters to both electrostatic headphone enthusiasts and
 newcomers alike. \n\nUltra-thin 68mm driver with copper plate electrodes\n\nThe EX-la features a 68mm diameter electrostatic driver made of high-grade, ultra-thin Mylar film. The diaphragm is driven by a pair of OFC copper plate electrodes, which is only 0.5mm thick. This provides powerful propulsion for the diaphragm, delivering
exceptional bass reproduction 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 lower distortion\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\nCNC-machined metal chassis with vintage-inspired styling\n\nThe EX-1a employs an all-metal chassis comprised of CNC-machined aluminum alloy, stainless steel frames enclosed in genuine buffalo leather. Maximum comfort is achieved by reducing weight and creating a slim contour. The retro, classic, yet elegant design of the EX-1a closely resembles 
vintage audio gear.\nPremium lambskin earpads and PC-Triple-C cable options\nEach earpad is crafted through a complex assembly 
process using selected genuine lambskin leather.
\n\n\n\n\n\n\n\nPC-Triple-C Pro Bias cabling with upgrade options\n\n\n\n\n\n\n\nThe Pro Bias connection of the driver is linked via a 6- core PC-Triple-C copper cable with insulation","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-ex-1a-electrostatic-headphones-1204377248.avif?v=1770988799","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-ex-1a-electrostatic-headphones-1204377251.avif?v=1770988799","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-ex-1a-electrostatic-headphones-1204377250.avif?v=1770988799","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-ex-1a-electrostatic-headphones-1204377252.avif?v=1770988799","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-ex-1a-electrostatic-headphones-1204377249.avif?v=1770988799","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-es-lab-headphone-es-lab-ex-1a-electrostatic-headphones-1204377247.avif?v=1770988799"],"price":1050,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.015Z"},"share_url":"https://firestarter.network/l/lst_HJG5xuWv","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
