From the makers of the very first in-ear headphones comes the Sony WF-C500 True Wireless In-Ear Headphones, a pair of earbuds that are made to feel like they are bespoke devices made just for you. Sony accomplished this by utilizing a huge amount of data on ear shapes from around the world, and crafting rounded, ergonomic earbuds that fit comfortably and securely. Use them to listen to your favorite music through 5.8mm dynamic drivers, and customize it to your specific tastes with the Sony Headphones Connect app.
