Noise-canceling headphones worth the price?

A little bit of silence. Sometimes that’s all we want. Whether it is halfway through a 10-hour flight with a crying baby or trying to sleep through the snoring from the hotel room next door, the     1     of noise-canceling headphones is one that every traveler probably finds charming. Yet are they worth it? These headphones are often expensive, and for some people, they don’t live up to the ads.

I’ve spent a     2     of the last five years traveling, taking dozens of flights and train journeys, and as someone who has reviewed noise-canceling headphones for even longer, I can definitely say maybe.

HOW THEY WORK? Noise-canceling headphones, also called active noise canceling headphones, use electronic processing to analyze nearby sound and attempt to     3     the opposite sound. The result is less noise, over all.

These headphones don’t create silence, nor are they able to     4     noise. The crests and troughs (波峰和波谷) do not perfectly cancel out. The absolute best noise-canceling headphones     5     reduce noise and work best with low-frequency droning sounds.

Two headphone sets could claim to reduce the same amount of noise but     6     completely differently. Only hands-on testing, ideally with objective measurements, can tell the difference.

Noise-canceling headphones require a battery to     7     their electronics. Noise-isolating headphones, which do not require electronics and therefore can be far cheaper, work by creating a seal in your ear canal to block noise. They are     8    like earplugs, but with earbuds. If you can get a good seal, these work reasonably well.

Getting a good seal can be a challenge, however, since everyone’s ears are different, and not all headphones will     9     correctly. And even if you do get a good seal, noise-isolating headphones will not be able to block low-frequency sounds as well as the best noise-canceling headphones. They will reduce a wide range of frequencies, which can help.

WHO REALLY NEEDS THEM? If you are a frequent traveler, good noise-canceling headphones will make any journey in a plane, train or automobile far more pleasant.

In-ear models are easier—though still slightly uncomfortable—to sleep with and are my     10    . Over-ear models reduce a little more noise, as they are able to passively block some sound because of their design. But they are always bulky on your head or in your bag. After I stopped reviewing these headphones for Wirecutter, I bought a pair of Bose QuiteComfort 20s, a long time Wirecutter pick, and I never fly without them.
