• The medium-size silicone ear pieces are attached when purchased. 

You may not enjoy the bass sound fully if the ear pieces do not fit your ears. To enjoy better sound while reducing sound leakage, choose the other pair 

of ear pieces (three sizes of silicone ear pieces) and adjust their positions to fit them to your ears.

• Attach the ear pieces firmly when replacing them; failure to do so may result in the ear pieces getting lodged in your ear canal when removed, thus 

becoming a possible health hazard.

• The ear pieces deteriorate with age even in normal use and maintenance.

• When this product gets dirty, clean the surface with a damp cloth. Do not wash with water
