Item promptly delivered and condition as described. Unfortunately clearly damaged in transit although adequately packaged in original box. Very speedy and no fuss refund arranged. I would strongly recommend this seller for his handling of this frustrating issue.

Excellent on delivery and very pleased with purchase. Many thanks.
I remember back in the eighties my father having a pair of these headphones. Which prompted me recently to find a pair. Well I’m about 7 pairs in so far, and have finally found a fully working pair that the pads have not gone flat on.
You will read online that Koss will supply replacement pads for only $5.00!! Which is fine if you living in the USA, but equate to about £60 in the UK via a European spares supplier.
The biggest issue I have found with vintage pro 4aa’s is either open circuit drivers, faulty jack leads, and even the cable running through the headband.
The biggest and most painful fault is the fact that the ear cushions shrink, and go hard. To a degree you can split the pads open and fill with foam, but this is by no means ideal, as ear cushions on most headphones do have an effect on overall sound quality.
If you do get a good pair, you will be pleasantly surprised with the sound quality. They really are good, considering the design is over 40 years old.
They are not lightweight, and not the most comfortable headset, but I found this was easily made up by the neutral and controlled sound quality. Not as flat as a pair of DT-100’s, but certainly more suitable for studio and easy listening.
The impedance of 250 ohms does render them not the loudest phones for use with portable devices, and they are not exactly a fashion statement. But for home hifi, or I’m the studio, they will handle a pounding.
I have many pairs of vintage Koss headphones, and these certainly were the most pioneering model they made. However the pro 4aaa is more comfortable and sound marginally better, even though they have a similar driver configuration.
I’m not saying they beat modern helpings from Sennheiser, AKG or Beyer. But for the curious audiophile or collector, they are worth a go.

Just buy them!!!
Doesn’t matter whether your a sound engineer or not, they headphones are worth every penny. Personally I found the treble a little to bright. This however is is made up by the fact that despite being closed back, they do not sound encapsulated. But other than that, they are comfortable, and lightweight. You won’t be disappointed.
