To those who prefer noise-canceling headphones without all the bulk, the Sony XBA-NC85D headphones are the perfect solution.
Normally, noise-cancellation headphones are large and bulky due to the need for batteries to activate the feature. Ear bud styles are OK for dealing with background noise, but it never fully blocks everything out. The Sony XBA-NC85D headphones deals with both problems. These are the world's smallest and lightest earphones on the market. Instead of the large battery unit commonly seen in headphones, Sony's managed to integrate this device inside the earphones. The quality of sound is also greatly improved thanks to the new Balanced Armatures. The batteries will last 20 hours on a single charge, allowing users to listen to music all day long.
