This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.

I bought 2 from this site and they arrived about 2 weeks later. They are the same exact headphones as my branded ones. Very happy for paying $4 each. Thanks.
EDIT: I have determined that these headphones are not the same quality, the battery of both pairs I bought are about 1/5 the life of the branded ones. There are not of similar quality, but the price was still very good.
