Summary: It really has a unique design with the bass masq. The design (those big eyes) really improve the bass performance slightly from the other cheap Sony in-ear and earbuds headphones. The audio quality is really cool with its 13.5mm driver units.
Pros: Stays in the ear perfectly and steadily, thanks to the gas mask
Cons: The bass is only slightly better than the other cheap Sony headphones, not as exaggerated
