9/1/2017, · If you feel ,dizziness, frequently after using earplugs I would recommend to change the brand you are using, or to use ,earmuffs, instead if you can, or to rest for a few days trying not to use earplugs (maybe weekend at home). As you see, no good solutions at any rate...
After prolonged use, the ear cushions of any ,earmuffs, will wear out and the ,insulation, foam inside the cups can get dirty or deteriorate. Both the ear cushions and the ,insulation, foam are user-replaceable and readily available for purchase in a hygiene kit.

Proper Fit: With ,ear muffs, over both ears while in a noisy environment, place the palms of your hands on both cups and push cushions towards head. If there is a perceptible difference in the noise level, ,ear muffs, are probably not fitted properly. The headband will take a set. If proper fit is not obtained, repeat fitting instructions.

Because the cranial bone also transmits vibrations to the eardrum, you will still hear louder noises. If you are looking for earplugs that attenuate ,sound,, you have various options.
Optimally inserted earplugs can provide better low-frequency noise reduction than ,earmuffs,. ,Earmuffs, and earplugs sold in the U.S. have to be accompanied by the NRR and a table that details attenuation by frequency octave band. Below is the table for a pair of NRR-30 rated ,earmuffs, (3M Peltor Optime 105) and a pair of NRR-30 foam earplugs (Howard Leight Max Lite).
