Sony have released a new active-noise cancellation ear-bud style headphones, model MDR-NC11. When the unit is switched on noise is reduced by 10dB. The specs on the website say that it cancels noise from 50Hz to 1,000 Hz, with a maximum of 10dB noise cancellation in the critical range from 100 to 400 Hz – where the human ear is super-sensitive.
