ESS has been in hi-fi audio since the 1970s, and now the company brings its expertise in speakers to the world of headphones. The 252 headphone is particularly eye-catching, with medium-density walnut ear cups and a shiny metal frame. It’s easy to travel with, too. The cables are removable, the frame collapses to fit in the included carrying case, and the 32-ohm impedance means you can drive this headphone with mobile sources. Built with custom 50-millimeter moving-coil drivers, the 252 aims to showcase the different traits of the amplifiers you pair it with, revealing the true nature of recordings while infusing them with its own personal sonic traits. Major Hi-Fi  praises the headphone’s warmth and richness, saying, “These cans sound great in almost every genre, especially rock. And for listeners with a softer temperament, the ESS 252 works perfectly for classical, too.”
