Dan Clark Audio AEON Tuning Kit

Formerly known as MrSpeakers, Dan Clark's headphones are hand-assembled in the USA, and their intensive sound research has resulted in a number of patents for technologies like their V-planar driver and TrueFlow magnet array. The headphones are all tuned by Clark, who favors a signature quite close to the Harman Response Curve, that tends to results in a smooth, powerful sound.
