INSERTING THE EARPHONES
If the earphone seems to be lacking in low frequency response (bass), check the tightness of the seal between the earphone and your ear, or try one of the other sleeve options.
Warning: Do not push the earphone sleeve beyond the ear canal opening.
To change earphone sleeve, twist and pull sleeve to remove it from the nozzle. Push new sleeve onto nozzle until you feel it slide completely over barb. If any part of the nozzle is exposed, sleeve is not properly installed. Replace sleeves if they do not grip the nozzle tightly
