High Fidelity Earphones are an excellent way to reduce sensory input without sacrificing on sound clarity! 

Noise reducing earphones not only lower damaging decibel levels by up to 22 decibels, but also significantly increase sound clarity. 

Unlike foam ear plugs, they never muffle sound, allowing you to carry on a conversation or listen to music without any problem. Enjoy clean, clear, and controlled sound.

They look like ear buds, so they don't draw attention; simply bring down the noise level.  If you opt for the clear variety, they are barely noticeable.

Many people with neurodiversity wish they could wear noise canceling headphones much of the day as auditory input can be especially overwhelming. However, noise canceling headphones are bulky, costly, socially awkward, and keep the user from  hearing critical information. 

Noise reducing earphones are ideal for school, public places, work, and play. They even provide enhanced protection for your ears. You can wear them all day and they are very comfortable. They range in price from $15-$40.

Noise reducing earphones can be a life changer, especially for people with sensory (auditory) issues. They can be purchased on Amazon and their are many different types to chose from. I believe Vibes was the originally manufacture.
