Sony has made the MDR XB-70AP with quality in its mind to satisfy the tradition of quality. The earphone has been made with the combination of soft fiber and plastic.
The plastic is strong and tightly attached to the body. Sony has attached soft plastic stress relief. The earbuds have an optimum length and it fits comfortably in the ear. The earphone features four ports - two small on driver housing and two big on the bass duct.
Good Sound Quality
The sound quality is really good. The bass quantity is good and it is capable of producing sub-bass sound too. The clarity at the higher end is decent. The high-quality aluminum housing reproduces dynamic and rich sound.
Note: These earphones are not originally manufactured Sony, These are the "A Copy" earphones. But the best part is, these are very similar to original Sony earphones in the aspect of built quality and sound.
