Every so often you will find a great pair of ear buds with great frequency response. Get them home and then can't figure out which is Left and which is Right, since the manufacturer decided to let you find this out for yourself.
I bought some Maxell headphones that clasp behind the back, Ouchies on the ears after 30 minutes! Went to WalMart (gah!) and oicked up some nice Koss ear buds. But... not L or R designators!
Knowing some ear plugs have channels reversed, only one way a person can tell is to use audio files.
So... ran through my files, and found two from Creative Labs. No copyrights on em, so guess they can be posted.
So here they are, !
Left and Right Channel Wave Files
Enjoy! And mark them ear buds!
