Sony XBA-4IP 4-Driver Balanced Armature in-ear headphones includes a full range driver, two added woofers and an extra tweeter - all micro-sized and tuned to perfection by Sony engineers. Marvel at the super smooth frequency response made possible by the double layer design that encloses the special magnesium inner housing inside an ABS outer housing that makes unwanted vibrations a thing of the past.
Select from 7 pairs of comfortable ear cushions and listen for longer since the natural noise blocking design discourages annoying distractions. Controlling your iPod, iPad or iPhone on the go is a breeze when you can switch tracks, turn down the volume, take calls and more with the in-line remote and built-in mic. Handy travel carrying pouch included.
