About this deal
I have only had them a few days and occasionally I think I can notice a difference, but an hour later, that isn’t the case. More than 25dB, and you'll experience a lot of noise reduction and even silence depending on your hearing. Do bear in mind that some experts wouldn't recommend wearing them 24/7 as they're unsure of how this might affect your hearing and auditory sensitivity in the long run. As with virtually every new piece of audio gear, I did not care for the effect – at first – it feels like your ears have a cold, it’s stuffy and sort of murky.
If you're extremely sensitive to sound, you might be best suited to a pair of the best noise-cancelling headphones or the best over-ear headphones.
This is ideal if you want the best of both worlds – sound that you choose or total silence – with the push of a button.
Instead, they reduce certain frequencies that the company says people find most irritating and distressing. When choosing earplugs for sleeping, it’s important to consider the NRR and select earplugs with a high enough rating to effectively block out unwanted noise.Now, the Calmer system is small, and if you fit them the wrong way you could end up losing them down your ear canal a bit too easily. During the testing period, each set of earplugs was used for a minimum of one week (but sometimes longer) and evaluated based on how it impacted our nightly sleep and noise levels.
