final earpiece E type ALL size 10 pieces Black FI-EPEBLBL2A4

■Optimal shape and materials provide a comfortable fit. By using silicone with an appropriate aspect ratio for each size and different hardness for the umbrella and shaft, the ear canal is less likely to be forced into contact with the ear canal, resulting in a comfortable fit. Comfortable wearing makes it possible to improve the bass range, improve sound insulation, and reduce irritating sounds in the high range, bringing out the original sound of the earphones. ■ Comes with an original earpiece case that is convenient to carry. Comes with a newly developed earpiece case engraved with the final logo. ■ Comes with an adapter that allows adjustment of the shaft diameter. The included adapter also supports earphones with a narrow shaft diameter of the sound pipe.
