New Delhi, Oct 4 (IANS): Extending its range of wireless headphones, Sony on Tuesday launched MDR-1000X, a noise cancelling headphone that comes with "Personal NC Optimiser" function and "Quick Attention" mode.

The Rs 30,990 device houses 40mm driver, has frequency response of 4Hz-40,000Hz, touch-enabled volume controls and has Bluetooth and Near Field Communication (NFC) features, the company said in a statement.
