The cans of Pro4S are smaller and tighter than lower DJ100/200 model. That is strange to me. Also I don't understand so low popularity of them. I bought mine for 89$ on MassDrop.

Actually the DJ100 stock pads have an inner diameter of 45mm. The Pro4s are D-shaped—matching an ear shape—an have a height of 55mm and width of 36mm.

I find the Pro4s fit much more comfortably.

Obviously it is individual. I would have Pro4S sound in DJ100 cans. For DJ200 second-hand price, mine cost 25$ ha-ha.

Definitely; fit is always subjective. The Pro4s fit me like a glove.

I've heard Koss has some exciting new things coming, so I'm hopeful! Being a Wisconsinite, I want to see Koss succeed with more "studio" models

Just got mine open box for $60. Also got a pair of SP540’s which I’m SUPER eager to try tonight! If I like the SP540’s I was gonna grab the Pro4s’s next.

BTW what is the difference between Pro4S and SP540?

Testing DJ200 vs Pro4S for a week 3-4 hrs per day. It seems like DJ200 has more comfort sound for me. A little bit more "nasal" (darker?), treble greedy, but less exhausting. Bass quality and mids density are also on DJ200.
