7. Califone Hearing Safe Hearing Protector
Price: $12.15
Smaller ear cups of these headphones are designed specifically to completely cover the ears of the students. They are a great tool for autistic children with hyper-reactivity to audio stimuli because they block external noise. The noise is muted enough to keep the child comfortable and at the same time able to hear instructions and engage in conversation. These headphones can only be used for blocking the noise which is usually enough for most children. If you want headphones which block the noise and are used for listening to music as well, then these are not the best choice. Some users also noted that these headphones are not as durable as the very expensive ones but the price compensates for such a design and they are easily replaceable with a new pair.
