Pioneer SE-20A is a great stereo headphones for it's price. A true vintage Pioneer that sounds amazing! Great bass, no distortion and beautiful ambiance. It's not as top as the Monitor 10's but delivers a pleasant and warm sound beating any new headphones in the same price range. Definitely a keeper!
Boy, the separation is better than any of my modern mics. Only neg is that it is heavy. I always test the headphone =s with Gergiev's Bolero on YT and this set is fabulous.
