THE EARTIPS SHOULD BE INSERTED ONLY IN THE ENTRANCE OF THE EAR-CANALdBud is not designed to reach very far into the ear-canal – and with the correct choice of size of eartips, dBud will seal sufficiently, without having to be pushed in too far.Just push the eartip slightly into the ear, while you make a twisting movement of the plug.If you are using the memory foam eartips; squeeze and compress them before inserting them, and they will then expand to the shape of the inside of your ears.The two outer circles on the neck of the plug enables two different positions of the eartip, so that you can make small adjustments to how far into the ear you want the eartip to go. Do not push the eartip fully down to the most inner circle that is closest to the plug body, because then the end of the neck is close to sticking out from the eartip, which is probably not very comfortable for you. The eartip should fully cover and cushion the hard plastic neck.FOAM TIPSSqueeze the foam tips before insertion. Then gently push the plug to the entrance of the ear-canal, while at the same time twisting the plug slightly.The foam tips expand after insertion in the ear and provide a slightly better seal and attenuation than the silicone tips.
