Using Your iHome Headphones The earpieces are marked L and R. Place the L earpiece in your left ear and the R earpiece in your right ear for proper fit and best sound. If the earpieces are inserted incorrectly they will not fit properly in your ears and the sound quality will not be satisfactory. For added stability the cables of these ear buds should be looped over your ears as shown in the following illustration. iHome iB12 Earphone is one of many Replacement Headset Parts available through Office Depot.
