At no point should someone considering buying these headphones think that they have anything to do with the old K-141 model, even though they look much alike.
These headphones have a decent sound quality and response. They are great for use as a backup when recording, or as a "second opinion" when mixing. You can also listen to music or watch movies.
Being supra-aural, they get uncomfortable to wear after a while, but that's expected. The self adjusting headband provides a perfect fit, but the earpads tend to get sticky and gummy after a few months, to the point of staining your clothes and your furniture with black goo, so you have to replace them, which costs more than you would think. You can't do anything to prevent this, except maybe wipe them before storing them, especially if you sweat much. But this will only postpone the damage.
Their power output is medium, you can't crank them up much, but that's not what they were made for.
Overall, they look good, they sound pretty good, but that's as far as it gets. Also, consider buying velour earpads.
