My boyfriend used them the day after they arrived and he wishes he had known about these before making such a big purchase on the others. 5 even th 9 I ordered was loose. Material chips too easily. glad I purchased! I was even able to whisper just to test it out & the other person could still hear me! Packaging:I am trying to understand idea behind the box. So, if you wear them out and get some funny glances, that might be why! Why dont you give me pass this time Amazon? My disgust isnt aimless. 1mm adapter in a small pouch velcroed to the back. I wear a size 7 1/8 hat, so I have a large/extra large head and these fit great.
