Koss Model R/90 Over the Ear Stereo Headphones w/ 1/8" and 1/4" Jacks - Tested

The headphones are in good and working condition.  At first look they look very good, but the foam over the speakers is starting to disintegrate.  The foam that goes around the ear seems to be normal, it is just the foam going across the speaker that is at issue.  The ear pads also have a fabric over the foam that is protecting it.  The foam over the speaker does not have that.

The headphones sound nice and are very comfortable over the ear.  It has some decent sound range and I didn't feel like the bass and treble were wanting.
