Excerpt: Sony has always liked the letter X. Who can forget Sony’s X-plod car amplifiers and the unfortunate connotations of X-plod when applied to automotive audio? Undaunted, Sony has introduced eleven new models of XBA headphones. XBA stands for “Experience Balanced Armature.” Who knew that experience began with an X?
Conclusion: The final words for Sony XBA-3 are that these headphones are really amazing and incorporate detailed higher frequencies. Moreover the quality gives a strong competition to already established leaders of markets like Shure and Etymotics. These earphones are offering something with which you can enjoy a rich, deep layered audio with quality noise isolation functionality.
Summary: Sony's high-end in-ear headphones are a surprising package. These headphones sound impressively musical, but could be slightly more detailed in higher frequencies. They're well constructed apart from an annoying cord design.
Pros: Good bass response, Clear treble, Well built
