The black MDR-1000X from Sony are industry-leading adaptive noise-cancelling wireless headphones with a wide frequency response (4 Hz to 40 kHz) capable of reproducing high-resolution audio either wired or via Bluetooth. The large 40mm neodymium drivers are built into a circumaural design that covers the ears, while the personal noise-cancelling optimizer adapts to your environment and eliminates noise in all conditions.
The built-in lithium-ion rechargeable battery is fully charged in four hours and provides up to 20 hours of music playback. Enjoy noise- and hands-free calling thanks to the integrated microphone, while all the touch-controls are housed in the right earcup. The MDR-1000X ships with a wired audio cable, charging USB cable, and a carrying case.
