Check Which Speaker Is Right Which Is Left
This tip came me while listening to new Moby song called “Shot in the back of the head”, which is available to download for free here.
The song starts with swinging sounds from left to right speaker but I listened with my old headphones that has no marks of R (right) and L (side) left, so I couldn’t determine if the song starts on the right side or on the left.
So to quickly solve this problem use simple trick. Open your computer’s volume control panel and move “Volume Control” or “Wave” slider to the left or right direction while listening to some music. If you hear the sound on your right when the slider is moved to the right, then it means you have put headphones correctly. If not, just switch the sides and you’ll be fine.
