Sony Twin Turbo Fontopia Earphones, model No. MDR-E535 - working!
Made in Japan in the late 80s. Features and includes the iconic wind-up case.
The packaging is open and slightly damaged; the earphones themselves are in excellent condition. There is no significant wear, and these work wonderfully. See video. They have the iconic Sony-stereo featuring a boosted bass that all products in this line carried in the 80s and 90s.
Both earphones work.
Note that this earphone set has an asymmetrical cord; it’s shorter on one side. This is also a classic Sony feature from this line.
The foam cushions are very fragile due to their old age (35+ years old).
You will want to remove them if using these as the foam is disintegrating. I’ve left them as is to preserve their original look.
Please reach out with any questions.
