Founded in 2007 in Paris by Pierre-Emmanuel Calmel, Quentin Sannié, and Emmanuel Nardin, Devialet revolutionized high-end audio with its groundbreaking Analog Digital Hybrid (ADH) technology. Calmel invented ADH in 2004, creating the foundation for Devialet's distinctive sound engineering. The company launched its first amplifier, D-Premier, in 2010, followed by the iconic Phantom speakers in 2014. After raising over €17 million and establishing global leadership in premium audio, Devialet expanded under Frank Lebouchard's leadership (CEO since 2018). Today's product portfolio includes Phantom speakers, Mania portable speakers, Gemini in-ear headphones, Dione soundbars, and Astra amplifiers. Based in Paris, Devialet combines French acoustical engineering excellence with innovative design, creating extraordinary audio experiences that restore sound's rightful place in modern life.
