I was immediately let down by them. I was taken aback by the number of rave testimonials. The sound quality is actually quite bad. It's artificial, there's no bass, and the "hump" about 3 kHz is unaffected by the most brutal equalization settings. It's like hearing the music amplified through a giant speaker. I spent a lot of time wrangling with the equalizer, hoping to find a way to vanquish this "humpback." There is no treatment, alas. Also, the bass isn't quite there yet, but there's some distortion near the tail end. After only 30 minutes of music on the drive to work, the want to toss them was overwhelming. Quickly, the ears became weary. The Panasonic "plugs" are outdated, and the Oklick is a cheap computer headset. They both sound fine and, unlike this Sennheiser model, won't bother your ears. The Sennheiser does not provide any form of soundproofing. The headphones fit loosely in the ears and can easily be knocked out. Don't buy them until you've given them a try! Blister, one-time use package. The problem arises with the following return.
