Query: Some assembly required

I don't know what headphones you people are talking about, but I got the Altec lansing AHP-712 ones and both of the earphones fell off within 15 minutes of having them out of the package.They are taped in with 4 small bits of cheap double sided tape. This is an outward sign of poor crafstmanship that is an indication of what is inside as well. Sure it comes with some trinkets, but the audio isn't that great. I haven't tried it with a battery in though so I don't know what they sound like with that. I have a huge head and they do fit!
