Koss audio products

Would appreciate some input on Koss audio products, I bought a Koss mp3/cd player that I play through my cassette deck with a converter, (sounds real good).my complaint is all the down time,when it should be playing, it flashes esp or volume 15 normal (or whatever volume is at time), mean while it seems to be searching or something.I just want to know if this is a poor product or is this normal?,the player is not being bounced around or anything, so I dont know why it's on skip protection so much. Thanks for any help.

Koss used to be known for excellent headphones and speakers about 20-25 years ago.

Their electronic products are all made by other manufacturers. I have 2 Koss car audio decks that are really Panasonics in drag.

Generally Koss stuff is fully featured yet inexpensive. My Koss portable CD player is pretty good, but the car decks will not read a CD unless I whack it on the side when I first load a disc. So their quality is not too good, IMO.
