Noise-Canceling Headphones Offer Silence

Summer means it's time to hit the road — but it also means the beginning of a long, noisy season of loud talkers, gum-snappers and cell-phone shouters. But luckily, there's a way to tune out other travelers in the minivan, the bus, the plane, or wherever the noise overwhelms you.

Noise-canceling headphones is your high-tech relief. While the name “noise-canceling” is a bit misleading (the noise is never really “canceled,” it’s just filtered or reduced), the positive effect of wearing them — the quiet on an airplane, the filtering of annoying outside distractions, the stress reducti -

on — is astounding. The technologies that create the “quiet” environment in your ears vary widely.

Skullcandy's Proletariat
One things about Skullcandy, is the price-to-value ratio. There may be slightly more effective noise-canceling headphones out there, but the SkullCandy Proletariat is easily the best value on the market — at least 70 percent less expensive than the most expensive option, and it works. Powered by two AAA batteries, the Proletariat headphones produce an audible “anti-sound” inside the headphones — a sound that effectively “cancels” the noise you’re hearing from outside. These reduce sound by about 18 decibels (a power lawnmower produces about 90 decibels) across the board without actually focusing on a particular frequency of sound. Plus, if you get a call, the headphone’s “LINK” technology mutes the music and takes the call. Combine that with a brilliant, even mind-boggling, pack-away hinge mechanism, and you have a low-cost winner. $99.95; skullcandy.com

Sony MDR-NC500D
Sony’s MDR-NC500D has a “feedback” microphone next to the ear, inside the earcup, which absorbs and calculates how much outside sound and what kind of sound (baby screaming, jet engine roaring, seatmate snoring) is getting in past the headphones, to your ear. The headphone’s digital software then cancels individually annoying frequencies of sound, even while it alllows the music - or movie you’re listening to sound great. There is even a button on the headphones that lets you recalibrate them for your situation. If the guy stops snoring, but the baby starts crying, you can adjust accordingly. $399; sonystyle.com

Sennheiser PXC 300
In between the low-cost Skullcandy and the high-end Sony is this option that has one undeniable advantage: These headphones are smaller than the other two and are more comfortable in hot weather. Plus, they sound great. The PXC 300’s quality is clear in the listening. It’s also a little different: Instead of “canceling” sound, Sennheiser’s internal “NoiseGard Advance” system cancels only some of the frequencies and boosts others — the so-called “mid-range” frequencies, f - or example — so it seems “clearer” and “quieter” to your ear. The small (1.75 inch) earpieces, the light weight and the comfort are great. A terrific mid-range choice for travelers. $219; sennheiserusa.com
