Gizmodo: Sony will begin selling headphones on April 21 that use digital technology to cancel roughly 99 per cent of ambient noise.
The MDR-NC500D headphones implement a new DNC software engine, which results in an impressive, 99% external noise cancellation.
With a maximum output of 100mW and a sensibility of 102dB/mW, expect these bad boys to pump some serious sounds.
Weighing in at 195g, they are a little on the heavy side, but if you’re a big traveller, these may be worth a look.
