I managed to loose one of the ear tips for my S4, I use the largest size that comes packaged with the S4's, and so I'm wondering if the largest size that comes is equivalent to the "Large" here, http://www.klipsch.com/na-en/products/exclusive-oval-ear-tips-overview/ and if it is, does anyone know of a good foam replacement that is sized for ear canals too "large" for the S4 "large" size? thanks!
