Design and Features
The MDR-3R continues the wired tradition of the MDR-3, with a USB-C connector. The headphones use 23 mm driver units. Sony says the new model has been engineered to reproduce a sound signature close to the original, with subtle refinements intended to suit modern listening preferences.
The headphones include an in-line remote control and an integrated microphone. There is no battery to charge, Bluetooth pairing to complete or firmware update to install. The MDR-3R supports USB Audio Class 1.0 devices, although Sony notes that compatibility and control functionality can vary depending on the connected hardware and software.
Sony says approximately 25% of the total plastic used in the MDR-3R is recycled material, with recycled plastic incorporated into the headphone body. The product also uses packaging designed to eliminate plastic packaging components, subject to Sony’s stated regional and material exclusions.
