Sony happens to have two new pairs of headphones designed for very particular segments of your life. If, say, you're a traveling music lover who doesn't happen to have the disposable income to obtain Sony's premium $300 MDR-NC300D noise canceling buds (which the company claims filter out 99 percent of noise), you'll find a cheaper alternative in the new $70 MDR-NC13, which only make a estimated 87.4 percent of background distractions go bye-bye. C'est la vie. If, on the other hand, you need to throw sound from one end of your mansion to the other for hours on end, the MDR-RF865RK wireless headphones might be the wide receiver you've been dreaming of -- Sony claims they'll play audio up to 100 meters away from their dock, which provides up to 25 hours of playtime after a 3.5 hour charge. No price or availability for the wireless cans, which were just announced in the UK, but you'll find the NC-13 on sale at Sony's online store right now. PR after the break.
