Question 1

How do I know if these fit? I feel like I have to work them in, and they don't go all the way in so they're flush with the end of my ear canal.

Accepted Answer

****  HOW DO I KNOW IF I HAVE ACHIEVED AN APPROPRIATE SEAL??***   You will need to insert both EARasers earplugs (Red is Right, Blue is Left - color side indicator stripes facing you, then bring straight back so line ultimately ends up facing towards the back of your head.)  Drop your jaw, and gently pull either up or down on your actual ear with one hand, while gently inserting your EARasers earplugs with the other hand.  The string with the ball is simply to help you remove it from your ear, so pressing on it won't hurt it.  Dropping your jaw will help to straighten your ear canal to achieve a better seal.  You will know you have an appropriate seal when YOU begin to speak.  While everything else will sound normal with EARasers inserted, your own voice, when speaking, should result in "a head voice" or "an occlusion when you speak".  Similar to you putting your fingers in your ears and speaking.  If you don't find that "head voice" when you speak, repeat the above steps to see if you can find that.  First, make sure you have Red in Right and Blue in Left and that the lines are positioned properly. (Often we see people rotate their hand while inserting and end up putting their earplug in Backwards. - Be certain you've not done this.)  EARasers should never hurt your ear canal, or be uncomfortable, however they do need to be able to seal your ear canal.  If you are certain that you've inserted both properly, and still have not achieved an appropriate seal so that your own speaking voice sounds muffled. (Remember everything else will sound normal - almost like there is only a slight volume different.) If you are unable to achieve your "head voice when speaking", then you many need to swap sizes.

Question 2

Are the little attennas visible while wearing them? Like if i look at myself in the mirror would i be able to see them?

Accepted Answer

Not likely, and they're not antennas.  They are utilized to be able to pull the device out of the ear.

Question 3

I think i was sent the wrong size - is there a way to measure to check?  packaging says both medium and extra-small in different places.

Accepted Answer

I would reach out to the seller or manufacture to see if they can help sort out which size you actually received.

Question 4

Are these the same as the ones listed as hi-fi high fidelity? if not, what is the difference?

Accepted Answer

Yes, I don't think there's any difference. The earplugs came in the box shown, which says "hi-fi."
