Video reviews
Additional features headphones Koss PRO 4AA:
  • THD (non-linear distortion factor): < 0.1%
  • Comfortable wide headband fits perfectly on head and distributes the entire weight of the earbuds over its entire area, which allows you to use them for several hours in a row
  • Headphone cups can be adjusted
From the press release:

The large membranes of these headphones are able to provide a good frequency response value, make the bass clearer, cleaner and deeper, and also minimize sound distortion. The magnetic cores of this model focus high energy, which allows you to enhance the bass and achieve good sensitivity.
