Re: Koss-PRO-4AA (1975)

These headphones are very strong, which gives them a huge flaw: they are too heavy and quickly become very uncomfortable! When you tilt your head forward they fall ...
Also the sound is not heard of the best ...

These were a very good value for the money back in the day. I think I paid between $60 and 70 in 1975. Truly spectacular sounding headphones, AKG, Sennheiser, Beyerdynamic etc. were easily double the money. These were highly favorable to the rock-n-roll sound and could play at extremely high levels with rock solid bass. No doubt the die-cast frames helped in this regard but also added to considerable weight. I have bought several upgrades in the decades since buying these, but I still keep them around the work shop were I repair vintage hifi. I know exactly what music should like through them, which makes them a known standard in which to determine the health of the system under test.
