I was blown away by the sound of the Sennheiser HD 598 when I spent some time auditioning a dozen headphones at our local Crutchfield store. I started with the $400 HiFiMan and the Senn HD 600, and worked my way down to a set I own, the Sennheiser HD 280 Pro. They stock Grado, Beats, Monster, Denon, B&W, AKG, Yamaha, PSB, Bose, Klipsch, Koss, and others.
The HD 598 had to be among the ugliest there but they were also the most comfortable and had the most impressive audio experience, IMHO. I've been thinking about them ever since and noticed today that the price has dropped on
Amazon.
