What King Sound does
King Sound, legally King's Audio Limited, is a Hong Kong-based manufacturer of electrostatic audio products founded in 2002. The company designs and produces a complete matched system spanning electrostatic and hybrid loudspeakers (PRINCESS III, Queen V, KS-17, KS-18, KS-31, KS-25 anniversary, KS-SUPER 2 tweeters, and the HT-series), electrostatic headphones (KS-H3, KS-H4), dedicated headphone amplifiers (portable M-03, solid-state M-10, tube OTL M-20), tube speaker amplifiers and pre-amplifiers (P-30, P-80, P-100, PP-10), and a CD source (CD-1). Its core technology uses thin-film electrostatic transducers driven by high-voltage bias, often combined with conventional dynamic woofers in hybrid configurations to extend bass response, with Mundorf M.Cap crossover components used in higher-end models.
The business model is hardware sales through a combination of a direct-by-appointment Hong Kong showroom and an international authorized dealer network spanning at least 10 countries including the UK, Italy, Canada, USA, China, Australia, France, Poland, Indonesia, and Japan. Pricing is not publicly disclosed, and revenue is not reported; sales are generated unit-by-unit through specialty high-end audio channels. Marketing is concentrated in high-end audio trade shows (High End Munich, SIAV Shanghai, HKAVPE, Audio & Visual Fiesta) and earned press in specialist publications (Stereophile, Fairaudio, ReMusic, Non Solo Audiofili, Hi-End Magazine Italy).
The company is privately held, founder/owner-operated (Simon Lai is identified as the public contact), with 11-50 employees and no external funding, M&A, or parent company structure disclosed. The customer base is concentrated in a single persona segment: audiophiles and high-end audio enthusiasts seeking low-distortion, high-transient-response sound reproduction. Recent strategic activity has centered on product innovation, including the 2024 global debut of the world's first hanging ultra-thin electrostatic speaker and the 2025 KS-25 25th anniversary edition.
