Oval shaped Earbuds .. Comfort, Fit, Noise Isolation When Klipsch started studying 3-dimensional ear impressions, it was discovered that nearly everyone has an oval-shaped ear canal. The company couldn't believe that no one else had considered the anatomical shape of the ear canal when designing in-ear headphones. The usual round earbuds squeezes itself unnaturally into your ear canal and exert extra pressure to the walls of your ear canal. Klipsch's oval earbuds fits easily and comfortably into the oval contours of your ear canals. This natural oval fit gives a perfect acoustic seal. A good seal minimizes outside noise, also known as noise isolation, and allows you to enjoy your music at lower, safer volumes. To make it comfortable for you to wear for extended period, Klipsch carefully selected a silicone material that is softer than most earbuds out there. Klipsch's earbuds are light and flexible to the touch, yet hardy and long lasting. It is washable and replaceable.
