Why is Sony Re-Launching a 1979 Headphone?
It’s a huge gamble for an electronics giant to relaunch a product it introduced nearly five decades ago. With the relaunched MDR-3R headphones (first launched in 1979), Sony blends the old and the new. It retains the form factor and components (earpads, drivers) of the original version (MDR-3) yet introduces modern-day features like USB-C connectivity and inline remote + mic.
