The SP51 sound preference in-ear headphone allows you to tune the sound to fit your preference with the simple change of the tuning ports. Switch from pounding bass to a relaxing, neutral sound, to a fun sound with a little enhanced bass any time you want without spending for three different headphones! Change the sound based on your preference that time, with specific music genres, or even with different media players. Sound tuning is achieved by changing the rear tuning ports with settings for enhanced bass (metallic, installed), extreme bass (black), and balanced (silver). The in-ear design provides passive sound isolation and the 10 mm driver provides dynamic full range sound. The SP51 housing is durable and comes with the standard MEE frustration-free cable you have grown to love.
