Founded around 2019-2020 in Shenzhen, China, HarmonicDyne is a relatively new audio company that emerged as the brainchild of Linsoul Audio, the Chinese headphone retail company founded in 2016 by the Crazy HiFi team. Operating under the umbrella of Shenzhen WeiLaiHao Science&Technology Co., Ltd., HarmonicDyne specializes in high-performance open-back headphones designed to deliver exceptional audio quality at accessible price points. The company gained recognition through successful crowdfunding campaigns for their flagship models: the Helios (their debut product), Zeus (featuring beryllium drivers), and Poseidon (incorporating maple accents and 50mm nickel diaphragm dynamic drivers). HarmonicDyne's philosophy centers on combining amazing acoustic performance, bespoke craftsmanship, and budget-friendly affordability to make high-end audio accessible to everyday music lovers. Their products are distributed globally through authorized retailers including Linsoul Audio and HiFiGo, with customer support handled through Linsoul's established infrastructure. The company continues designing and manufacturing headphones that deliver superior sound quality while maintaining accessibility for diverse audiences, establishing themselves within the competitive audiophile headphone market through innovative engineering and strategic crowdfunding launches.
