Limitations
Noise-cancelling headphones have several limitations (that vary from vendor to vendor):
- They consume power, usually supplied by a USB port or a battery that must occasionally be replaced or recharged. Without power the headsets function like a regular headset, without active noise cancellation, or do not function at all.
- They may introduce additional noise, usually in the form of high-frequency hiss.
- The noise-cancelling circuitry required for them to operate inherently reduces audio quality.
- Early models were generally bulkier than traditional headphones. However, newer models tend to incorporate the batteries in pre-existing space. While this usually reduces the bulk, it does not reduce the extra weight of noise-cancelling headphones compared to traditional headphones.
- They are also more expensive than regular headphones

Famous quotes containing the word limitations:
“That all may be so, but when I begin to exercise that power I am not conscious of the power, but only of the limitations imposed on me.”
—William Howard Taft (1857–1930)
“The limitations of pleasure cannot be overcome by more pleasure.”

“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
