Sony headphones eliminate 75 percent of ambient noise

The whole point of wearing headphones is to be able to hear what’s coming through the ‘phones or ‘buds. If you hear too much from outside, you might as well be listening to exterior speakers.

Sony has taken that message to heart with the new MDR-NC22(JE) headphones, which the company claims can cut out up to 75 percent of outside noise.

That’s a big number. Here’s another: 50 hours of running time. That’s what you’ll get out of just one AAA battery, which is what the MDR-NC22(JE) headphones run on. One number that’s missing from the picture, however, is price. We still have to wait on that.
