I have yet to use this bone headphone tonight but for the price it cost me it rvle correct. Indeed I have been given (the headphone straight out of the 80's I think), the sound is well equilibrated (relative low, mid, treble) although a little aggressive on the highs and saturating but sometimes in the lower to feel both dsagrements, push the volume. A system that screwed jack lets you toggle between the Diameter of references. Finally, the headphone is nice (vintage and all!) But not suited for DJing trs.
