If you think there is no earphone that is good enough to deflect unwanted noise while you are listening to your songs, then you are wrong. Sony has just released their latest awesome noise reduction earphones and headphone dubbed as MDR-NC33, MDR-NC300D and MDR-N600D, with up to 99% noise cancellation!
The Sony MDR-NC300D earphone mainly has three interesting modes for noise cancellation. Starting from A mode for General Mode or Movie), B mode for Airplane environment, and C for busy environments (Trains Bus, Office, Pub, etc).
While Sony MDR-NC300D can suppress up to 98.4%, the lower end MDR-NC33 can only suppress 90% undesired noises. If you desire for the the most excellent performance in noise reduction, you may want to throw your sight to the Over-Head headphone MDR-N600D which capable of suppressing up to 99%.
No Price mentioned yet, but by judging from the past series, it should be available around $60 to $100.
