I have a technician that has something like one of these and is absolute garbage

You cant hear nothing and it is so uncomfortable to use in your ear

I still have yet to figure out a use for the horn attachment because it is very hard to pinpoint a problem when the horn attachment is on

Posted by a reviewer on Amazon

I really do not know what you could use it for but anyone wanting to know that the horn attachment is actually made of a molded rubber as i thought it was made out of plastic which i do not think it good

Posted by a reviewer on Amazon

Rubber will absorb the noise which will muffle the symptom you are trying to diagnose and on the other hand plastic doesnt do that

Posted by a reviewer on Amazon

It bounces off the plastic which would send noise into the tube and into the ear but that is my personal preference and also so i have been told but i could be wrong

Just for the people wondering though that when you put it into your ear it isnt very comfortable to wear
