The MDR-1R Premium Headphones made by Sony are a pair of closed-back circumaural type headphones that feature 40mm liquid crystal polymer film drivers and a frequency response of 4Hz - 80kHz.
Their design is distinguished by red silicone rings located between the ear cups and headband, these work as silent joints made to reduce rattle. For listening precision and comfort, ear cushions wrap around the ears and have an acoustic seal.
In addition, the headphones come with an in-line microphone control located on the cord for hands-free communication with Apple devices such as the iPod, iPhone and iPad. The right-angled, gold-plated 1/8" (3.5mm) mini-stereo plug is located at the end of the cable for a secure connection. A carrying pouch is included for safety and protection while on the go.
