So to answer your question, yes they are worth it if you need them to reduce the background noise and allow you to hear the sounds you want to hear, but don’t expect high end sound quality from any of them, even though they might cost the same as high end headphones.
Is Noise Cancelling bad for you?
Unlike cell phones, noise-cancelling headphones do not emit low level radiation and do not pose any of the potential hazards that could stem from frequent use of a cell phone held next to the ear. Acute loud noises can damage hearing, interfere with sleep, raise blood pressure and stress levels and cause headaches.
Do you need noise Cancelling?
That’s because noise-canceling headphones do more than reduce noise. You can even use noise-canceling headphones if you don’t want to listen to another audio source but do want to cancel out background noise. And a little bit of quiet can be music to anyone’s ears.
Are cheap noise Cancelling headphones worth it?
Cheap earplugs, or perhaps noise-isolating earbuds, might work well enough. And it’s worth keeping in mind that for the same money, regular headphones will likely sound better than noise-canceling headphones. As earplugs are lower in cost, they might be worth trying first.
Why is noise Cancelling so expensive?
This occurs through the use of active noise control. Moreover, they also restrict high-frequency noise through the use of soundproofing. So, noise cancelling headphones are expensive than other headphones.
