Pioneer SE-20 Stereo Headphones

The Pioneer SE-20A headphones are stereo headphones that were produced from 1970–1973. They have double earpieces and 8 ohm impedance. Some say that they have a "Ye Olden Days of Headphones" charm. Others say that they are a budget-priced headphone set that produces virtually distortion-free sound.
