Summary: The night I was invited to play my records and got interviewed for one hour on a local radio station, my friend who presents this program brought five of these headphones with him. These headphones were meant as a support for this small regional radio station in the Netherlands called Radio Voorst. My friend's name is Huub Boel, owner of the Bo-El Guitar Company. Before starting the radio show I helped him unboxing and installing the headphones in the radio room.
Pros: Great sound / comfortable head fit / reasonable price
Summary: I purchased a Koss Pro4AAA while a freshman in college in the mid 1970's. I was about to throw it away as one of the speakers stopped working. I recently purchased several headphones from Amazon (great deals of the days), and read about Koss' lifetime warranty. I sent my old headphones to Koss and they repaired them like new for only a $9 shipping fee. These are still the best headphones I have ever had.
Absolut empfehlenswert, ein kleiner / großer Kraftprotz

Summary: Der Pro-4AA Titanium ist für mich persönlich das Maß, an dem sich alle anderen Kopfhörer messen lassen müssen. Mit ca. 1,2 Kg ist er zwar relativ schwer, und durch den engen aber komfortablen Sitz fangen die Ohren auch schon mal das Schwitzen an, aber der Klang entschädigt für alles!
