Dan Clark Audio
MrSpeakers was founded with a simple goal in mind. To make great headphone products and have fun doing it. Founded by Dan Clark, an electrical engineer who has been working in and around the high-end audio market for more than twenty years.
Now after a realisation that they aren't a speaker company but a specialilsed personal audio company, they have rebranded to Dan Clark Audio. Still the same great sounding headphones but now number a different name.
