Slicsound is a soft, precisely shaped ear piece designed and molded to fit most popular in-ear monitor buds or just ordinary personal stereo earphones. Made from a special FDA approved silicone, they are custom-fitted to be worn comfortably and safely for long time periods. Slicsound works by creating an acoustic chamber that is said to direct incoming sound correctly into the aural cavity thereby cutting out all ambient or background noise. This would make music more distinct and clearer but with less overall volume required.
