Yes, noise cancelling headphones can help you sleep. While there’s no guarantee that they’ll help you get a sound night of sleep, they can certainly help.
If you know that the main reason you struggle to get to sleep at night is due to ambient noise, then you could really benefit from noise cancelling headphones.
If you live in a busy city with sounds of traffic and footfall at night, or you’re even just disturbed by home appliance humming or weather sounds then it’s worth giving this type of headphones a go.
The difference between regular headphones and noise cancelling models is that the latter are specially designed to block out low-frequency sounds. As a result, you’d expect that they could help contribute to a great night’s sleep.
