I used the last in 1992! Before I'd had the headphones has k7 Aiwa walkmans, etc. .. lol nothing to see what the akg K140 my father, not very comfortable .. this sony headphones was a revelation for me, I've still enjoy al use.
I have since 1992! at the base he served for stereo listening, especially rap, he served sometimes djing, polyvalent.les foams were comfortable, they are dead, I must replace the thin plastic layer imitating leather for a very long disappeared.
solid years saw use is always nice, good bass without exaggeration. his big jack Once released, and has seen the good service that I made him my headphone is put a good Neutrik.
al age j dared put on the bus to school and fesait me reflections of the kind it is big your headphone, you look like a mickey etc., in fact it was too far ahead of his time, al-age people wanted a headphone discrete, today the mid-dree beats headphones etc it goes unnoticed
the quality is very nice, very good balance of frequencies, stereo image too, sound quality is good, the isolation was good for the era, today it is better but it's okay. the only negative point of this headset is that it strains the ears after a few hours, so we listen to an entire album very nice way and then passes something else if need another headset whose sound is more neutral but less pleasant you can spend the night in general .. when I take the headphones to listen to c is a good rap album
