Bose? Have a look at Sony's latest, the MDR-NC300D. These flashy earbuds boast an in-line noise-canceling module with three separate modes: a general mode, airplane mode and one for trains / buses / cars. Granted, we get the idea that those selections are a bit of marketing hype, but whatever the case, Sony asserts that these buds will eliminate up to 99 percent of undesired jibber jabber. All that's required is a single AA cell, which should provide right around 20 hours of noise suppression. Interested? Pony up ¥40,900 ($415) and prove it.
